Maven 搭建SpringMVC+Hibernate項目詳解

更新時間：2016年09月06日 16:52:41 作者：Andyzty

本文主要介紹Maven 搭建SpringMVC+Hibernate的知識，這里整理了詳細的資料，并附示例代碼，有興趣的小伙伴可以參考下

前言

今天復習一下SpringMVC+Hibernate的搭建，本來想著將Spring-Security權(quán)限控制框架也映入其中的，但是發(fā)現(xiàn)內(nèi)容太多了，Spring-Security的就留在下一篇吧，這篇主要搭建SpringMVC4.1.4和Hibernate4.3.8，之前也打了好多SpringMVC的，這部分已經(jīng)非常的熟悉了，畢竟業(yè)開發(fā)過一年多SpringMVC的，這次持久層采用Hibernate，數(shù)據(jù)源采用c3p0，數(shù)據(jù)庫暫采用MySQL，主要是想復習一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：

1、設計數(shù)據(jù)庫：設計好表結(jié)構(gòu)，最好符合3NF，采用Hibernate tools將設計好的表自動生成對應的實體entity。

1、創(chuàng)建Maven項目，按需映入Maven包依賴。

2、搭建Spring：配置Spring對控件層Bean的注入。

3、搭建Hibernate：配置數(shù)據(jù)源，配置SessionFactory，配置事務，以及二級緩存ehcache的配置。

4、測試Spring+Hibernate的框架搭建，寫單元測試JUnit，測試事務配置等。

5、映入SpringMVC：配置SpringMVC配置信息。

6、配置web.xml容器

7、測試三個框架的整合：Maven編譯打包部署服務器，測試。

1、數(shù)據(jù)庫設計

設計一個權(quán)限、角色、用戶的表。自然如果一個用戶可以有多個角色，一個角色多個用戶所擁有；一個角色擁有多個權(quán)限，一個權(quán)限對應多個角色。所以按照數(shù)據(jù)庫表結(jié)構(gòu)設計，符合3NF的話我們需要5張表進行存在。表的具體信息就不列出了（可以下在源碼，里面還有數(shù)據(jù)庫），表關(guān)系如下：

這里面ID才用到是java的UUID（36位）

2、創(chuàng)建Maven項目，編寫pom.xml文件

創(chuàng)建一個Maven的webapp項目，編寫pom.xml文件，引入所需的包依賴，我這里就將所需的全部的映入了。

pom.xml文件內(nèi)容如下:

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3、引入Spring配置

編寫配置文件，配置文件放在src/main/resources資源目錄下（下同）。

項目所需的配置信息config.properties

 

#application configs

#jdbc c3p0 config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 12345

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-4.1.xsd">
 <!-- 加載配置文件 -->
 
 <context:property-placeholder location="classpath:config.properties"/>
 <!-- 掃描service自動注入為bean -->
 <context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" />

</beans>

上面spring配置了對應包下組件bean自動注入管理，我們需要將dao,service的實現(xiàn)類交由spring管理，如（@Repository，@Service）。

3.2、引入日志文件配置Log4j

 log4j.properties的配置文件如下：

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

4、Hibernate配置

Hibernate的配置主要包括：配置數(shù)據(jù)源c3p0，配置SessionFactory，配置事務管理器，配置事務管理，其spring-hibernate.xml文件如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xsi:schemaLocation="
 http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
 http://www.springframework.org/schema/tx 
 http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
 http://www.springframework.org/schema/aop 
 http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

 <!-- 配置數(shù)據(jù)源 c3p0 -->
 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
 destroy-method="close">
 <property name="driverClass" value="${jdbc.driver}" />
 <property name="jdbcUrl" value="${jdbc.url}" />
 <property name="user" value="${jdbc.username}" />
 <property name="password" value="${jdbc.password}" />

 <!-- 請求超時時間 -->
 <property name="checkoutTimeout" value="30000" />
 <!-- 每60秒檢查所有連接池中的空閑連接。默認值: 0，不檢查 -->
 <property name="idleConnectionTestPeriod" value="30" />
 <!-- 連接數(shù)據(jù)庫連接池最大空閑時間 -->
 <property name="maxIdleTime" value="30" />
 <!-- 連接池初始化連接數(shù) -->
 <property name="initialPoolSize" value="5" />
 <property name="minPoolSize" value="5" />
 <property name="maxPoolSize" value="20" />
 <!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數(shù)。默認值: 3 -->
 <property name="acquireIncrement" value="5" />
 </bean>

 <!-- 配置hibernate的SessionFactory -->
 <bean id="sessionFactory"
 class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
 <!-- 注入數(shù)據(jù)源 相關(guān)信息看源碼 -->
 <property name="dataSource" ref="dataSource" />
 <!-- hibernate配置信息 -->
 <property name="hibernateProperties">
 <props>
 <prop key="hibernate.dialect">${hibernate.dialect}</prop>
 <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
 <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
 <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

 <!-- 開啟二級緩存 ehcache -->
 <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>
 <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
 <prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop>
 <prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}
 </prop>
 </props>
 </property>
 <!-- 掃描hibernate注解配置的entity -->
 <property name="packagesToScan" value="org.andy.work.entity" />
 </bean>

 <!-- 配置事務管理器 -->
 <bean id="transactionManager"
 class="org.springframework.orm.hibernate4.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" />
 </bean>

 <!-- 配置事務增強處理Bean，指定事務管理器 -->
 <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
 <!-- 配置詳細事務處理語義 -->
 <tx:attributes>
 <tx:method name="insert*" propagation="REQUIRED" />
 <tx:method name="update*" propagation="REQUIRED" />
 <tx:method name="delete*" propagation="REQUIRED" />

 <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
 <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
 <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
 <tx:method name="load*" propagation="SUPPORTS" read-only="true" />

 <!-- 其他采用默認事務方式 -->
 <tx:method name="*" />

 </tx:attributes>
 </tx:advice>

 <!-- Spring aop事務管理 -->
 <aop:config>
 <!-- 配置切入點 -->
 <aop:pointcut id="transactionPointcut"
 expression="execution(* org.andy.work.service..*Impl.*(..))" />
 <!-- 指定在txAdvice切入點應用txAdvice事務增強處理 -->
 <aop:advisor pointcut-ref="transactionPointcut"
 advice-ref="transactionAdvice" />
 </aop:config>

</beans>

上面配置了二級緩存，ehcache，相關(guān)的具體信息查看上一篇Hibernate二級緩存以及ehcache的搭建配置，下面是二級緩存的配置。

4.1、ehcache.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
 <diskStore path="D:/ehcache" />
 <!-- DefaultCache setting. -->
 <defaultCache
 maxElementsInMemory="1000"
 eternal="false"
 timeToIdleSeconds="120"
 timeToLiveSeconds="120"
 maxElementsOnDisk="1000000"
 overflowToDisk="true" 
 memoryStoreEvictionPolicy="LRU">
 
 </defaultCache>

 <!-- Special objects setting. -->

 <cache 
 name="org.andy.work.entity.AcctUser"
 maxElementsInMemory="2"
 memoryStoreEvictionPolicy="LRU" 
 eternal="true" 
 diskPersistent="false"
 overflowToDisk="false" 
 maxElementsOnDisk="1000000" /> 



</ehcache>

上面Hibernate二級緩存ehcache存放磁盤是D:/ehcache

5、生成業(yè)務entity實體

設計好數(shù)據(jù)表后，Hibernate的實體有工具Hibernate tools自動生成，Eclipse需要安裝Hibernate tools插件（我在線安裝過幾次都不成功，推薦使用links離線安裝，附錄將介紹），所以不需要手工的書寫，下面就貼一個用戶信息的實體，AcctUser.java

 

package org.andy.work.entity;

// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0

import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

/**
 * AcctUser generated by hbm2java
 */
@Entity
@Table(name = "acct_user", catalog = "work")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class AcctUser implements java.io.Serializable {

 /**
 * 
 */
 private static final long serialVersionUID = 6980093847795726310L;
 private String id;
 private String nickName;
 private String telephone;
 private Date registerTime;
 private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0);

 public AcctUser() {

 }

 public AcctUser(String id, String nickName) {
 this.id = id;
 this.nickName = nickName;
 }

 public AcctUser(String id, String nickName, String telephone,
 Date registerTime, Set<AcctRole> acctRoles) {
 this.id = id;
 this.nickName = nickName;
 this.telephone = telephone;
 this.registerTime = registerTime;
 this.acctRoles = acctRoles;
 }

 @Id
 @Column(name = "id", unique = true, nullable = false, length = 36)
 public String getId() {
 return this.id;
 }

 public void setId(String id) {
 this.id = id;
 }

 @Column(name = "nick_name", nullable = false)
 public String getNickName() {
 return this.nickName;
 }

 public void setNickName(String nickName) {
 this.nickName = nickName;
 }

 @Column(name = "telephone")
 public String getTelephone() {
 return this.telephone;
 }

 public void setTelephone(String telephone) {
 this.telephone = telephone;
 }

 @Temporal(TemporalType.TIMESTAMP)
 @Column(name = "register_time", length = 19)
 public Date getRegisterTime() {
 return this.registerTime;
 }

 public void setRegisterTime(Date registerTime) {
 this.registerTime = registerTime;
 }

 @JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})
 @ManyToMany(fetch = FetchType.LAZY)
 @Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
 @JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })
 public Set<AcctRole> getAcctRoles() {
 return this.acctRoles;
 }

 public void setAcctRoles(Set<AcctRole> acctRoles) {
 this.acctRoles = acctRoles;
 }

}

上面有幾個需要注意的：

上面大多數(shù)都是Hibernate tools自動生成的，但是有幾個需要手動添加：

1、如果這個實體使用二級緩存的話，需要添加@cache注解；

2、如果該實體里面還有集合元素（set， map，list），如果實體要采用二級緩存，那么這些集合元素必須也添加@cache注解。

3、@JsonIgnoreProperties注解是為了防止SpringMVC在json返回時產(chǎn)生循環(huán)輸出使用，如果不配置的話就會出現(xiàn)json死循環(huán)（還有多對多，一對多的屬性時）。

4、@JsonIgnore這個是在轉(zhuǎn)換成json是忽略該屬性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})則是忽略acctRoles里面的acctUsers和acctAuthorites屬性。

6、創(chuàng)建Dao層

6.1Dao接口

Dao層和Service層我們肯定采用的是面相接口編程的思想，所以，我們先定義一個通用的Dao接口，GenericDao.java

 

package org.andy.work.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 創(chuàng)建時間：2015-2-6 下午2:26:42
 * 
 * @author andy
 * @version 2.2
 * 
 * Dao通用接口
 */

interface GenericDao<T, PK extends Serializable> {
 
 T load(PK id);
 
 T get(PK id);
 
 List<T> findAll();
 
 void persist(T entity);
 
 PK save(T entity);
 
 void saveOrUpdate(T entity);
 
 void delete(PK id);
 
 void flush();
}

在定義具體的UserDao.java接口

package org.andy.work.dao;

import org.andy.work.entity.AcctUser;

/**
 * 創(chuàng)建時間：2015-2-6 下午2:43:50
 * 
 * @author andy
 * @version 2.2
 * 
 * 用戶Dao接口
 */

public interface UserDao extends GenericDao<AcctUser, String> {

}

6.2、Dao層實現(xiàn)類

我們需要將Dao層的實現(xiàn)類注入為bean，所以需要添加@Repository注解，UserDaoImpl如下：

package org.andy.work.dao.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

/**
 * 創(chuàng)建時間：2015-2-6 下午2:45:14
 * 
 * @author andy
 * @version 2.2
 */
@Repository("userDao")
public class UserDaoImpl implements UserDao {

 @Autowired
 private SessionFactory sessionFactory;

 private Session getCurrentSession() {
 return this.sessionFactory.getCurrentSession();
 }

 @Override
 public AcctUser load(String id) {
 return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);
 }
 
 @Override
 public AcctUser get(String id) {
 return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);
 }

 @SuppressWarnings("unchecked")
 @Override
 public List<AcctUser> findAll() {
 List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();
 return acctUsers;
 }

 @Override
 public void persist(AcctUser entity) {
 this.getCurrentSession().persist(entity);

 }

 @Override
 public String save(AcctUser entity) {
 return (String) this.getCurrentSession().save(entity);
 }

 @Override
 public void saveOrUpdate(AcctUser entity) {
 this.getCurrentSession().saveOrUpdate(entity);
 }

 @Override
 public void delete(String id) {
 AcctUser entity = this.load(id);
 this.getCurrentSession().delete(entity);
 }

 @Override
 public void flush() {
 this.getCurrentSession().flush();

 }

}

7、創(chuàng)建Service層

7.1、Service層接口

package org.andy.work.service;

import java.util.List;

import org.andy.work.entity.AcctUser;

/**
 * 創(chuàng)建時間：2015-2-6 下午3:18:57
 * 
 * @author andy
 * @version 2.2
 * userService接口
 */

public interface UserService {
 AcctUser load(String id);

 AcctUser get(String id);

 List<AcctUser> findAll();

 void persist(AcctUser entity);

 String save(AcctUser entity);

 void saveOrUpdate(AcctUser entity);

 void delete(String id);

 void flush();
}

7.2、service層實現(xiàn)類

UserServiceImpl就需要注入上面定義的Dao層bean。

package org.andy.work.service.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 創(chuàng)建時間：2015-2-6 下午3:24:16
 * 
 * @author andy
 * @version 2.2 UserService 的實現(xiàn)
 */
@Service("userService")
public class UserServiceImpl implements UserService {

 @Autowired
 private UserDao userDao;

 @Override
 public AcctUser load(String id) {
 return userDao.load(id);
 }

 @Override
 public AcctUser get(String id) {
 return userDao.get(id);
 }

 @Override
 public List<AcctUser> findAll() {
 return userDao.findAll();
 }

 @Override
 public void persist(AcctUser entity) {
 userDao.persist(entity);
 }

 @Override
 public String save(AcctUser entity) {
 return userDao.save(entity);
 }

 @Override
 public void saveOrUpdate(AcctUser entity) {
 userDao.saveOrUpdate(entity);
 }

 @Override
 public void delete(String id) {
 userDao.delete(id);
 }

 @Override
 public void flush() {
 userDao.flush();
 }

}

8、測試Spring和Hibernate的整合

我們可以在src/test/java編寫測試類，測試上面的配置，如果測試成功已經(jīng)基本大功告成。

package org.andy.work.service;

import java.util.Date;
import java.util.List;
import java.util.UUID;

import org.andy.work.entity.AcctUser;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**
 * 創(chuàng)建時間：2015-2-6 下午3:31:07
 * 
 * @author andy
 * @version 2.2
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
 "classpath:spring-hibernate.xml" })
public class TestUserService {

 private static final Logger LOGGER = Logger
 .getLogger(TestUserService.class);

 @Autowired
 private UserService userService;

 @Test
 public void save() {
 AcctUser acctUser = new AcctUser();
 acctUser.setId(UUID.randomUUID().toString());
 acctUser.setNickName("andy");
 acctUser.setRegisterTime(new Date());
 acctUser.setTelephone("13022221111");
 String id = userService.save(acctUser);
 LOGGER.info(JSON.toJSONString(id));
 }

}

9、引入SpringMVC

添加spring-mvc.xml文件

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
 xsi:schemaLocation="http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
 http://www.springframework.org/schema/context 
 http://www.springframework.org/schema/context/spring-context-4.1.xsd 
 http://www.springframework.org/schema/mvc 
 http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

 <!-- 自動掃描@Controller注入為bean -->
 <context:component-scan base-package="org.andy.work.controller" />

 <!-- 以下為SpringMVC配置 -->
 <mvc:annotation-driven>
 <!-- 返回json數(shù)據(jù)，@response使用 -->
 <mvc:message-converters register-defaults="true">
 <bean
 class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
 <property name="supportedMediaTypes">
 <list>
 <value>text/html;charset=UTF-8</value>
 <value>application/json;charset=UTF-8</value>
 </list>
 </property>

 </bean>
 </mvc:message-converters>
 </mvc:annotation-driven>

 <!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前后綴 -->
 <bean
 class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="viewClass"
 value="org.springframework.web.servlet.view.JstlView" />
 <property name="prefix" value="/WEB-INF/views" />
 <property name="suffix" value=".jsp" />
 </bean>

</beans>

上面配置了包掃描Controller，[email protected]��，和視圖層的配置。

10、配置web.xml容器

web容器是web項目的大腦，所以web容器，首先需要引入spring，讓spring管理各個框架，并將其注入為bean。然后配置控制層的filter信息。并且配置了springmvc攔截的url為以.hmls結(jié)尾的請求。

web.xml文件如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
 id="WebApp_ID" version="2.5">

 <display-name>springmvc_demo</display-name>

 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
 </context-param>

 <filter>
 <filter-name>encodingFilter</filter-name>
 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
 <init-param>
 <param-name>encoding</param-name>
 <param-value>utf-8</param-value>
 </init-param>
 <init-param>
 <param-name>forceEncoding</param-name>
 <param-value>true</param-value>
 </init-param>
 </filter>
 <filter-mapping>
 <filter-name>encodingFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

 <!-- openSessionInView配置 作用是延遲session關(guān)閉到view層 -->
 <filter>
 <filter-name>openSessionInViewFilter</filter-name>
 <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
 <init-param>
 <param-name>singleSession</param-name>
 <param-value>true</param-value>
 </init-param>
 </filter>

 <!-- 監(jiān)聽servletContext，啟動contextConfigLocation中的spring配置信息 -->
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <!-- 防止spring內(nèi)存溢出監(jiān)聽器 -->
 <listener>
 <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
 </listener>

 <servlet>
 <description>spring mvc servlet</description>
 <servlet-name>rest</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <init-param>
 <param-name>contextConfigLocation</param-name>
 <!-- 此處配置的是SpringMVC的配置文件 -->
 <param-value>classpath:spring-mvc.xml</param-value>
 </init-param>
 <load-on-startup>1</load-on-startup>
 </servlet>

 <servlet-mapping>
 <servlet-name>rest</servlet-name>
 <url-pattern>*.htmls</url-pattern>
 </servlet-mapping>

 <filter-mapping>
 <filter-name>openSessionInViewFilter</filter-name>
 <url-pattern>*.htmls</url-pattern>
 </filter-mapping>

 <!-- 配置session超時時間，單位分鐘 -->
 <session-config>
 <session-timeout>30</session-timeout>
 </session-config>

 <welcome-file-list>
 <welcome-file>/index.jsp</welcome-file>
 </welcome-file-list>
</web-app>

11、創(chuàng)建控制層Controller

控制層UserController

package org.andy.work.controller;

import java.util.List;

import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/** 
 * 創(chuàng)建時間：2015-2-7 上午11:49:00 
 * @author andy 
 * @version 2.2 
 * 描述： 用戶Controller
 */
@Controller
@RequestMapping("/user")
public class UserController {

 private static final Logger LOGGER = Logger.getLogger(UserController.class);
 
 @Autowired
 private UserService userService;
 
 @RequestMapping("/showInfo/{userId}")
 public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
 LOGGER.info("查詢用戶：" + userId);
 AcctUser userInfo = userService.load(userId);
 modelMap.addAttribute("userInfo", userInfo);
 return "/user/showInfo";
 }
 
 @RequestMapping("/showInfos")
 public @ResponseBody List<AcctUser> showUserInfos(){
 LOGGER.info("查詢用戶全部用戶");
 List<AcctUser> userInfos = userService.findAll();
 return userInfos;
 }
}

12、創(chuàng)建視圖層

在src/main/webapp/WEB-INF/views下創(chuàng)建user/showInfo.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%
 String path = request.getContextPath();
 String basePath = request.getScheme() + "://"
 + request.getServerName() + ":" + request.getServerPort()
 + path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<base href="<%=basePath%>" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
<title>userInfo</title>
</head>
<body>
 用戶信息 昵稱： ${userInfo.nickName} 用戶id：${userInfo.id} 用戶電話:${userInfo.telephone } 注冊時間：
 <fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" />
 角色：[
 <c:forEach items="${ userInfo.acctRoles}" var="role">
  ${role.name } 權(quán)限[
  <c:forEach items="${ role.acctAuthorities}" var="authority">
  ${authority.name } 
  </c:forEach> ]
  </c:forEach>
 ]

 <br /> ajax顯示全部用戶信息：
 <div id="show_all_user"></div>
</body>
<script type="text/javascript">
 $.ajax({
 type : "get",
 url : "user/showInfos.htmls",
 dataType : "json",
 success : function(data) {
 $(data).each(
 function(i, user) {
 var p = "<p>昵稱:" + user.nickName + " 電話:"
 + user.telephone + " 注冊時間:"
 + user.registerTime + " id:" + user.id +
 "</p>";
 $("#show_all_user").append(p);
 });
 },
 async : true
 });
</script>
</html>

13、部署服務器測試

使用Maven打包部署：clean compile package

部署到tomcat，測試
主要測試上面的 http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls （json數(shù)據(jù)返回）
上面視圖層就包含了這兩條url請求的測試：
