SpringMVC 整合SSM框架詳解

更新時(shí)間：2021年08月30日 11:01:38 作者：秦疆狂神說(shuō)

這篇文章主要介紹了SpringMVC 整合SSM框架詳解,本篇文章通過(guò)簡(jiǎn)要的案例,講解了該項(xiàng)技術(shù)的了解與使用,以下就是詳細(xì)內(nèi)容,需要的朋友可以參考下

整合SSM

環(huán)境要求

環(huán)境：

IDEA
MySQL5.7.19
Tomcat9
Maven3.6

要求：

需要熟練掌握MySQL數(shù)據(jù)庫(kù)，Spring，JavaWeb及MyBatis知識(shí)，簡(jiǎn)單的前端知識(shí)；

數(shù)據(jù)庫(kù)環(huán)境

創(chuàng)建一個(gè)存放書(shū)籍?dāng)?shù)據(jù)的數(shù)據(jù)庫(kù)表

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '書(shū)id',
`bookName` VARCHAR(100) NOT NULL COMMENT '書(shū)名',
`bookCounts` INT(11) NOT NULL COMMENT '數(shù)量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'從入門(mén)到放棄'),
(2,'MySQL',10,'從刪庫(kù)到跑路'),
(3,'Linux',5,'從進(jìn)門(mén)到進(jìn)牢');

基本環(huán)境搭建

1、新建一Maven項(xiàng)目！ssmbuild ，添加web的支持

2、導(dǎo)入相關(guān)的pom依賴！

       <artifactId>spring-jdbc</artifactId>
       <version>5.1.9.RELEASE</version>
   </dependency>
</dependencies>

3、Maven資源過(guò)濾設(shè)置

<build>
   <resources>
       <resource>
           <directory>src/main/java</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
       <resource>
           <directory>src/main/resources</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
   </resources>
</build>

4、建立基本結(jié)構(gòu)和配置框架！

com.kuang.pojo
com.kuang.dao
com.kuang.service
com.kuang.controller
mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

applicationContext.xml

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

</beans>

Mybatis層編寫(xiě)

1、數(shù)據(jù)庫(kù)配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2、IDEA關(guān)聯(lián)數(shù)據(jù)庫(kù)

3、編寫(xiě)MyBatis的核心配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   
   <typeAliases>
       <package name="com.kuang.pojo"/>
   </typeAliases>
   <mappers>
       <mapper resource="com/kuang/dao/BookMapper.xml"/>
   </mappers>

</configuration>

4、編寫(xiě)數(shù)據(jù)庫(kù)對(duì)應(yīng)的實(shí)體類(lèi) com.kuang.pojo.Books 使用lombok插件！

package com.kuang.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
   
   private int bookID;
   private String bookName;
   private int bookCounts;
   private String detail;
   
}

5、編寫(xiě)Dao層的 Mapper接口！

package com.kuang.dao;

import com.kuang.pojo.Books;
import java.util.List;

public interface BookMapper {

   //增加一個(gè)Book
   int addBook(Books book);

   //根據(jù)id刪除一個(gè)Book
   int deleteBookById(int id);

   //更新Book
   int updateBook(Books books);

   //根據(jù)id查詢,返回一個(gè)Book
   Books queryBookById(int id);

   //查詢?nèi)緽ook,返回list集合
   List<Books> queryAllBook();

}

6、編寫(xiě)接口對(duì)應(yīng)的 Mapper.xml 文件。需要導(dǎo)入MyBatis的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
       PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.kuang.dao.BookMapper">

   <!--增加一個(gè)Book-->
   <insert id="addBook" parameterType="Books">
      insert into ssmbuild.books(bookName,bookCounts,detail)
      values (#{bookName}, #{bookCounts}, #{detail})
   </insert>

   <!--根據(jù)id刪除一個(gè)Book-->
   <delete id="deleteBookById" parameterType="int">
      delete from ssmbuild.books where bookID=#{bookID}
   </delete>

   <!--更新Book-->
   <update id="updateBook" parameterType="Books">
      update ssmbuild.books
      set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
      where bookID = #{bookID}
   </update>

   <!--根據(jù)id查詢,返回一個(gè)Book-->
   <select id="queryBookById" resultType="Books">
      select * from ssmbuild.books
      where bookID = #{bookID}
   </select>

   <!--查詢?nèi)緽ook-->
   <select id="queryAllBook" resultType="Books">
      SELECT * from ssmbuild.books
   </select>

</mapper>

7、編寫(xiě)Service層的接口和實(shí)現(xiàn)類(lèi)

接口：

package com.kuang.service;

import com.kuang.pojo.Books;

import java.util.List;

//BookService:底下需要去實(shí)現(xiàn),調(diào)用dao層
public interface BookService {
   //增加一個(gè)Book
   int addBook(Books book);
   //根據(jù)id刪除一個(gè)Book
   int deleteBookById(int id);
   //更新Book
   int updateBook(Books books);
   //根據(jù)id查詢,返回一個(gè)Book
   Books queryBookById(int id);
   //查詢?nèi)緽ook,返回list集合
   List<Books> queryAllBook();
}

實(shí)現(xiàn)類(lèi)：

package com.kuang.service;

import com.kuang.dao.BookMapper;
import com.kuang.pojo.Books;
import java.util.List;

public class BookServiceImpl implements BookService {

   //調(diào)用dao層的操作，設(shè)置一個(gè)set接口，方便Spring管理
   private BookMapper bookMapper;

   public void setBookMapper(BookMapper bookMapper) {
       this.bookMapper = bookMapper;
  }
   
   public int addBook(Books book) {
       return bookMapper.addBook(book);
  }
   
   public int deleteBookById(int id) {
       return bookMapper.deleteBookById(id);
  }
   
   public int updateBook(Books books) {
       return bookMapper.updateBook(books);
  }
   
   public Books queryBookById(int id) {
       return bookMapper.queryBookById(id);
  }
   
   public List<Books> queryAllBook() {
       return bookMapper.queryAllBook();
  }
}

OK，到此，底層需求操作編寫(xiě)完畢！

Spring層

1、配置Spring整合MyBatis，我們這里數(shù)據(jù)源使用c3p0連接池；

2、我們?nèi)ゾ帉?xiě)Spring整合Mybatis的相關(guān)的配置文件；spring-dao.xml

<?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.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">

   <!-- 配置整合mybatis -->
   <!-- 1.關(guān)聯(lián)數(shù)據(jù)庫(kù)文件 -->
   <context:property-placeholder location="classpath:database.properties"/>

   <!-- 2.數(shù)據(jù)庫(kù)連接池 -->
   <!--數(shù)據(jù)庫(kù)連接池
       dbcp 半自動(dòng)化操作 不能自動(dòng)連接
       c3p0 自動(dòng)化操作（自動(dòng)的加載配置文件 并且設(shè)置到對(duì)象里面）
   -->
   <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
       <!-- 配置連接池屬性 -->
       <property name="driverClass" value="${jdbc.driver}"/>
       <property name="jdbcUrl" value="${jdbc.url}"/>
       <property name="user" value="${jdbc.username}"/>
       <property name="password" value="${jdbc.password}"/>

       <!-- c3p0連接池的私有屬性 -->
       <property name="maxPoolSize" value="30"/>
       <property name="minPoolSize" value="10"/>
       <!-- 關(guān)閉連接后不自動(dòng)commit -->
       <property name="autoCommitOnClose" value="false"/>
       <!-- 獲取連接超時(shí)時(shí)間 -->
       <property name="checkoutTimeout" value="10000"/>
       <!-- 當(dāng)獲取連接失敗重試次數(shù) -->
       <property name="acquireRetryAttempts" value="2"/>
   </bean>

   <!-- 3.配置SqlSessionFactory對(duì)象 -->
   <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       <!-- 注入數(shù)據(jù)庫(kù)連接池 -->
       <property name="dataSource" ref="dataSource"/>
       <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
       <property name="configLocation" value="classpath:mybatis-config.xml"/>
   </bean>

   <!-- 4.配置掃描Dao接口包，動(dòng)態(tài)實(shí)現(xiàn)Dao接口注入到spring容器中 -->
   <!--解釋 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       <!-- 注入sqlSessionFactory -->
       <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
       <!-- 給出需要掃描Dao接口包 -->
       <property name="basePackage" value="com.kuang.dao"/>
   </bean>

</beans>

3、Spring整合service層

<?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.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd">

   <!-- 掃描service相關(guān)的bean -->
   <context:component-scan base-package="com.kuang.service" />

   <!--BookServiceImpl注入到IOC容器中-->
   <bean id="BookServiceImpl" class="com.kuang.service.BookServiceImpl">
       <property name="bookMapper" ref="bookMapper"/>
   </bean>

   <!-- 配置事務(wù)管理器 -->
   <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       <!-- 注入數(shù)據(jù)庫(kù)連接池 -->
       <property name="dataSource" ref="dataSource" />
   </bean>

</beans>

Spring層搞定！再次理解一下，Spring就是一個(gè)大雜燴，一個(gè)容器！對(duì)吧！

SpringMVC層

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
        version="4.0">

   <!--DispatcherServlet-->
   <servlet>
       <servlet-name>DispatcherServlet</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
           <param-name>contextConfigLocation</param-name>
           <!--一定要注意:我們這里加載的是總的配置文件，之前被這里坑了！-->  
           <param-value>classpath:applicationContext.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
       <servlet-name>DispatcherServlet</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>

   <!--encodingFilter-->
   <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>
   </filter>
   <filter-mapping>
       <filter-name>encodingFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>
   
   <!--Session過(guò)期時(shí)間-->
   <session-config>
       <session-timeout>15</session-timeout>
   </session-config>
   
</web-app>

2、spring-mvc.xml

<?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"
      xmlns:mvc="http://www.springframework.org/schema/mvc"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/mvc
   https://www.springframework.org/schema/mvc/spring-mvc.xsd">

   <!-- 配置SpringMVC -->
   <!-- 1.開(kāi)啟SpringMVC注解驅(qū)動(dòng) -->
   <mvc:annotation-driven />
   <!-- 2.靜態(tài)資源默認(rèn)servlet配置-->
   <mvc:default-servlet-handler/>

   <!-- 3.配置jsp 顯示ViewResolver視圖解析器 -->
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
       <property name="prefix" value="/WEB-INF/jsp/" />
       <property name="suffix" value=".jsp" />
   </bean>

   <!-- 4.掃描web相關(guān)的bean -->
   <context:component-scan base-package="com.kuang.controller" />

</beans>

3、Spring配置整合文件，applicationContext.xml

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

   <import resource="spring-dao.xml"/>
   <import resource="spring-service.xml"/>
   <import resource="spring-mvc.xml"/>
   
</beans>

配置文件，暫時(shí)結(jié)束！Controller 和視圖層編寫(xiě)

1、BookController 類(lèi)編寫(xiě) ，方法一：查詢?nèi)繒?shū)籍

@Controller
@RequestMapping("/book")
public class BookController {

   @Autowired
   @Qualifier("BookServiceImpl")
   private BookService bookService;

   @RequestMapping("/allBook")
   public String list(Model model) {
       List<Books> list = bookService.queryAllBook();
       model.addAttribute("list", list);
       return "allBook";
  }
}

2、編寫(xiě)首頁(yè) index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<html>
<head>
   <title>首頁(yè)</title>
   <style type="text/css">
       a {
           text-decoration: none;
           color: black;
           font-size: 18px;
      }
       h3 {
           width: 180px;
           height: 38px;
           margin: 100px auto;
           text-align: center;
           line-height: 38px;
           background: deepskyblue;
           border-radius: 4px;
      }
   </style>
</head>
<body>

<h3>
   <a href="${pageContext.request.contextPath}/book/allBook" rel="external nofollow" >點(diǎn)擊進(jìn)入列表頁(yè)</a>
</h3>
</body>
</html>

3、書(shū)籍列表頁(yè)面 allbook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
   <title>書(shū)籍列表</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="stylesheet">
</head>
<body>

<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>書(shū)籍列表 —— 顯示所有書(shū)籍</small>
               </h1>
           </div>
       </div>
   </div>

   <div class="row">
       <div class="col-md-4 column">
           <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook" rel="external nofollow" >新增</a>
       </div>
   </div>

   <div class="row clearfix">
       <div class="col-md-12 column">
           <table class="table table-hover table-striped">
               <thead>
               <tr>
                   <th>書(shū)籍編號(hào)</th>
                   <th>書(shū)籍名字</th>
                   <th>書(shū)籍?dāng)?shù)量</th>
                   <th>書(shū)籍詳情</th>
                   <th>操作</th>
               </tr>
               </thead>

               <tbody>
               <c:forEach var="book" items="${requestScope.get('list')}">
                   <tr>
                       <td>${book.getBookID()}</td>

                           <a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}" rel="external nofollow" >更改</a> |
                           <a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}" rel="external nofollow" >刪除</a>
                       </td>
                   </tr>
               </c:forEach>
               </tbody>
           </table>
       </div>
   </div>
</div>

4、BookController 類(lèi)編寫(xiě) ，方法二：添加書(shū)籍

@RequestMapping("/toAddBook")
public String toAddPaper() {
   return "addBook";
}

@RequestMapping("/addBook")
public String addPaper(Books books) {
   System.out.println(books);
   bookService.addBook(books);
   return "redirect:/book/allBook";
}

5、添加書(shū)籍頁(yè)面：addBook.jsp

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

<html>
<head>
   <title>新增書(shū)籍</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="stylesheet">
</head>
<body>
<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>新增書(shū)籍</small>
               </h1>
           </div>
       </div>
   </div>
   <form action="${pageContext.request.contextPath}/book/addBook" method="post">
      書(shū)籍名稱(chēng)：<input type="text" name="bookName"><br><br><br>
      書(shū)籍?dāng)?shù)量：<input type="text" name="bookCounts"><br><br><br>
      書(shū)籍詳情：<input type="text" name="detail"><br><br><br>
       <input type="submit" value="添加">
   </form>

</div>

6、BookController 類(lèi)編寫(xiě) ，方法三：修改書(shū)籍

@RequestMapping("/toUpdateBook")
public String toUpdateBook(Model model, int id) {
   Books books = bookService.queryBookById(id);
   System.out.println(books);
   model.addAttribute("book",books );
   return "updateBook";
}

@RequestMapping("/updateBook")
public String updateBook(Model model, Books book) {
   System.out.println(book);
   bookService.updateBook(book);
   Books books = bookService.queryBookById(book.getBookID());
   model.addAttribute("books", books);
   return "redirect:/book/allBook";
}

7、修改書(shū)籍頁(yè)面 updateBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
   <title>修改信息</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="stylesheet">
</head>
<body>
<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>修改信息</small>
               </h1>
           </div>
       </div>
   </div>

   <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
       <input type="hidden" name="bookID" value="${book.getBookID()}"/>
      書(shū)籍名稱(chēng)：<input type="text" name="bookName" value="${book.getBookName()}"/>
      書(shū)籍?dāng)?shù)量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>
      書(shū)籍詳情：<input type="text" name="detail" value="${book.getDetail() }"/>
       <input type="submit" value="提交"/>
   </form>

</div>

8、BookController 類(lèi)編寫(xiě) ，方法四：刪除書(shū)籍

@RequestMapping("/del/{bookId}")
public String deleteBook(@PathVariable("bookId") int id) {
   bookService.deleteBookById(id);
   return "redirect:/book/allBook";
}

配置Tomcat，進(jìn)行運(yùn)行！

到目前為止，這個(gè)SSM項(xiàng)目整合已經(jīng)完全的OK了，可以直接運(yùn)行進(jìn)行測(cè)試！這個(gè)練習(xí)十分的重要，大家需要保證，不看任何東西，自己也可以完整的實(shí)現(xiàn)出來(lái)！

項(xiàng)目結(jié)構(gòu)圖

小結(jié)及展望

這個(gè)是SSM整合案例，一定要爛熟于心！

SSM框架的重要程度是不言而喻的，學(xué)到這里，大家已經(jīng)可以進(jìn)行基本網(wǎng)站的單獨(dú)開(kāi)發(fā)。但是這只是增刪改查的基本操作?？梢哉f(shuō)學(xué)到這里，大家才算是真正的步入了后臺(tái)開(kāi)發(fā)的門(mén)。也就是能找一個(gè)后臺(tái)相關(guān)工作的底線。

或許很多人，工作就做這些事情，但是對(duì)于個(gè)人的提高來(lái)說(shuō)，還遠(yuǎn)遠(yuǎn)不夠！

我們后面還要學(xué)習(xí)一些 SpringMVC 的知識(shí)！
