Maven 搭建SpringMVC+Hibernate項(xiàng)目詳解
更新時(shí)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(shí)，這里整理了詳細(xì)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(fù)習(xí)一下SpringMVC+Hibernate的搭建，本來(lái)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(kāi)發(fā)過(guò)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(kù)暫采用MySQL，主要是想復(fù)習(xí)一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：
1、設(shè)計(jì)數(shù)據(jù)庫(kù)：設(shè)計(jì)好表結(jié)構(gòu)，最好符合3NF，采用Hibernate tools將設(shè)計(jì)好的表自動(dòng)生成對(duì)應(yīng)的實(shí)體entity。
1、創(chuàng)建Maven項(xiàng)目，按需映入Maven包依賴。
2、搭建Spring：配置Spring對(duì)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(wù)，以及二級(jí)緩存ehcache的配置。
4、測(cè)試Spring+Hibernate的框架搭建，寫(xiě)單元測(cè)試JUnit，測(cè)試事務(wù)配置等。
5、映入SpringMVC：配置SpringMVC配置信息。
6、配置web.xml容器
7、測(cè)試三個(gè)框架的整合：Maven編譯打包部署服務(wù)器，測(cè)試。
1、數(shù)據(jù)庫(kù)設(shè)計(jì)
設(shè)計(jì)一個(gè)權(quán)限、角色、用戶的表。自然如果一個(gè)用戶可以有多個(gè)角色，一個(gè)角色多個(gè)用戶所擁有；一個(gè)角色擁有多個(gè)權(quán)限，一個(gè)權(quán)限對(duì)應(yīng)多個(gè)角色。所以按照數(shù)據(jù)庫(kù)表結(jié)構(gòu)設(shè)計(jì)，符合3NF的話我們需要5張表進(jìn)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(kù)），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(xiàng)目，編寫(xiě)pom.xml文件
創(chuàng)建一個(gè)Maven的webapp項(xiàng)目，編寫(xiě)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:

3、引入Spring配置
編寫(xiě)配置文件，配置文件放在src/main/resources資源目錄下（下同）。
項(xiàng)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(dòng)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(duì)應(yīng)包下組件bean自動(dòng)注入管理，我們需要將dao,service的實(shí)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(wù)管理器，配置事務(wù)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"

xsi:schemaLocation="

<!-- 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(dāng)連接池中的連接耗盡的時(shí)候c3p0一次同時(shí)獲取的連接數(shù)。默認(rèn)值: 3 -->
<property name="acquireIncrement" value="5" />
</bean>
<!-- 配置hibernate的SessionFactory -->
<bean id="sessionFactory"

</props>
</property>
<!-- 掃描hibernate注解配置的entity -->

</bean>
<!-- 配置事務(wù)管理器 -->

<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config>
</beans>
上面配置了二級(jí)緩存，ehcache，相關(guān)的具體信息查看上一篇Hibernate二級(jí)緩存以及ehcache的搭建配置，下面是二級(jí)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(jí)緩存ehcache存放磁盤(pán)是D:/ehcache
5、生成業(yè)務(wù)entity實(shí)體
設(shè)計(jì)好數(shù)據(jù)表后，Hibernate的實(shí)體有工具Hibernate tools自動(dòng)生成，Eclipse需要安裝Hibernate tools插件（我在線安裝過(guò)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(shū)寫(xiě)，下面就貼一個(gè)用戶信息的實(shí)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 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(gè)需要注意的：
上面大多數(shù)都是Hibernate tools自動(dòng)生成的，但是有幾個(gè)需要手動(dòng)添加：
1、如果這個(gè)實(shí)體使用二級(jí)緩存的話，需要添加@cache注解；
2、如果該實(shí)體里面還有集合元素（set， map，list），如果實(shí)體要采用二級(jí)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(shí)產(chǎn)生循環(huán)輸出使用，如果不配置的話就會(huì)出現(xiàn)json死循環(huán)（還有多對(duì)多，一對(duì)多的屬性時(shí)）。
4、@JsonIgnore這個(gè)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(gè)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(shí)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(shí)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(shí)現(xiàn)類
我們需要將Dao層的實(shí)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(shí)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(shí)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(shí)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;

@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public AcctUser load(String id) {
return userDao.load(id);
}
@Override

8、測(cè)試Spring和Hibernate的整合
我們可以在src/test/java編寫(xiě)測(cè)試類，測(cè)試上面的配置，如果測(cè)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(shí)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(dòng)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(duì)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(xiàng)目的大腦，所以web容器，首先需要引入spring，讓spring管理各個(gè)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(qǐng)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(tīng)servletContext，啟動(dòng)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(tīng)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(shí)時(shí)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(shí)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:${userInfo.telephone } 注冊(cè)時(shí)間：
<fmt:formatDate value="${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(cè)時(shí)間:"
+ user.registerTime + " id:" + user.id +
"</p>";
$("#show_all_user").append(p);
});
},
async : true
});
</script>
</html>
13、部署服務(wù)器測(cè)試
使用Maven打包部署：clean compile package
部署到tomcat，測(cè)試
主要測(cè)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(qǐng)求的測(cè)試：
ok，到此Spring+SpringMVC+Hibernate搭建完畢。
