spring、springMVC和mybatis的集成

1、关于三大框架的介绍我在这就不多说了，既然要学三大框架的集成，那说明已经掌握了他们各自的用法了并能够单独使用了，下面我来讲一下三大框架的集成

1.1 其实ssm的集成比ssh的集成简单很多，spring和springMVC的无缝结合给我们省了很多配置，首先我们创一个web项目，我这里用的是myeclipes没有用maven搭建，然后导入项目所需jar包,关于jar的话，spring和springMVC并不需要额外的jar包，只需要额外加入mybatis-spring.jar包，该包由mybatis提供，关于jar包在此不做跟多的说明。

下面给出本项目所用的spring4.0.2的jar包下载连接：http://download.csdn.net/detail/hing2008/6940551

mybatis3.2.6+mybatis-spring1.2.2 的链接：http://download.csdn.net/detail/aaa5438438/9586717

1.2 首先我们在项目中配置如下目录结构，为了之后配置文件中配置和最后的测试，再在项目中创建一个与src同级的包，在这个包下的文件在发布时也是在classes文件夹下和放在src目录下没有区别，这样做是为了方便配置，得到的结构如下图：

图 1.1

2、接下来我们要在在config包下书写配置文件

2.1 首先我们先配置一下我们连接数据库所需文件，在config包下创建jdbc.properties文件如下图：

图1.2

2.2 然后我们创建一个springmvc.xml文件（三个框架整合没有它什么事，先配了再说），这个配置文件只负责生成各种handler，映射路径什么的，为了管理起来更加轻松我把spring和springmvc的配置文件都放在config/spring目录下

<?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:p="http://www.springframework.org/schema/p"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-4.0.xsd                          http://www.springframework.org/schema/context                          http://www.springframework.org/schema/context/spring-context-4.0.xsd                          http://www.springframework.org/schema/mvc                          http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!--自动扫描，里面填你的controller所在的包 --><context:component-scan base-package="com.ssm.controller"/><!-- 处理静态资源 和解放MVC的原有功能--><mvc:default-servlet-handler/><mvc:annotation-driven></mvc:annotation-driven><!--文件上传配置 --><bean id="multipartResolver"            class="org.springframework.web.multipart.commons.CommonsMultipartResolver">         <!-- 默认编码 -->          <property name="defaultEncoding" value="utf-8" />            <!-- 文件大小最大值 -->          <property name="maxUploadSize" value="10485760000" />            <!-- 内存中的最大值 -->          <property name="maxInMemorySize"  value="40960" />        </bean>       <!-- 视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsps/"/><property name="suffix" value=".jsp" />  </bean></beans>

2.2 然后我们来配一下spring和mybatis整合文件applicationContext-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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:task="http://www.springframework.org/schema/task"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"><!-- 引入配置文件 --><bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="location" value="classpath:jdbc.properties" /></bean><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="${driver}" /><property name="url" value="${url}" /><property name="username" value="${username}" /><property name="password" value="${password}" /><!-- 连接池最大数量 --><property name="maxActive" value="30"></property><!-- 连接池最大空闲 --><property name="maxIdle" value="5"></property></bean><!--spring与mybatis整合--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 自动扫描mapping.xml文件 --><!--<property name="mapperLocations" value="classpath:com/ssm/mapping/*.xml"></property>--><!-- 全局配置 --><!-- 若不保留mybatis配置文件用上面那条替换这一条 --><property name="configLocation" value="classpath:mybatis/sqlMapConfig.xml"/></bean><!-- DAO接口所在包名，Spring会自动查找其下的类 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!-- 扫描包路径，需要扫描多个包中间用逗号隔开 --><property name="basePackage" value="com.ssm.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean></beans>

2.3 然后我们在配一下事务的文件applicationContext-transaction.xml，这个文件其实可以和上面一个文件写在一起，为了跟简单的管理配置，我把他写开了

<?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:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:task="http://www.springframework.org/schema/task"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"><!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 数据源dataSource在applicationContext-dao.xml中配置了--><property name="dataSource" ref="dataSource" /></bean><!-- 启用事务 --><tx:annotation-driven transaction-manager="transactionmanager" /></beans>

2.4 下一步是配置业务层的文件applicationContext-services.xml,这个文件也可以直接写在applicationContext-dao.xml中，为了。。。。。同上

<?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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:task="http://www.springframework.org/schema/task"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"><!-- 自动扫描 --><context:component-scan base-package="com.ssm.service.impl"/></beans>

2.5 最后我们再配置mybatis的配置文件sqlMapConfig.xml如果你在applicationContext-dao.xml中没有采用全局配置，这个文件就可以不用写，当然在这里我们还是要写的

<?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>       <mappers>        <!-- 注册userMapper.xml文件 -->        <mapper resource="com/ssm/mapping/UserMapper.xml"/>     </mappers>  </configuration>

自此我们三大框架集成所要配的容器文件配置完了，我们应该有如下目录结构

2.6 最后一步，在web.xml文件中配置spring和springmvc的容器，就是上面的那些配置文件

<?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"      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"      version="3.0">      <display-name>Archetype Created Web Application</display-name>          <!-- Spring容器和mybatis的配置文件 -->      <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>/WEB-INF/classes/spring/applicationContext-*.xml</param-value>      </context-param>        <!-- Spring监听器 -->      <listener>          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>      </listener>      <!-- 防止Spring内存溢出监听器 -->      <listener>          <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>      </listener>        <!-- 加载springMVC容器 -->      <servlet>          <servlet-name>SpringMVC</servlet-name>          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>          <init-param>             <param-name>contextConfigLocation</param-name>           <param-value>classpath:spring/springmvc.xml</param-value>          </init-param>          <load-on-startup>1</load-on-startup>          <async-supported>true</async-supported>      </servlet>      <servlet-mapping>          <servlet-name>SpringMVC</servlet-name>          <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->          <url-pattern>/</url-pattern>      </servlet-mapping>        <!-- 编码过滤器 -->      <filter>          <filter-name>encodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>          <async-supported>true</async-supported>          <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>           <welcome-file-list>          <welcome-file>/index.jsp</welcome-file>      </welcome-file-list>    </web-app>

好了，到这里我们是真的真的配完了。。。。

3、测试集成是否成功

3.1、在数据库中创建表user_t

/*Navicat MySQL Data TransferSource Server         : localhost_3306Source Server Version : 50536Source Host           : localhost:3306Source Database       : ssmTarget Server Type    : MYSQLTarget Server Version : 50536File Encoding         : 65001Date: 2016-07-26 10:30:37*/SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for user_t-- ----------------------------DROP TABLE IF EXISTS `user_t`;CREATE TABLE `user_t` (  `id` int(11) NOT NULL AUTO_INCREMENT,  `user_name` varchar(40) NOT NULL,  `password` varchar(255) NOT NULL,  `age` int(4) NOT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=202 DEFAULT CHARSET=utf8;-- ------------------------------ Records of user_t-- ----------------------------INSERT INTO `user_t` VALUES ('2', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('3', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('4', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('5', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('6', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('7', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('8', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('9', '测试1', '123456', '18');INSERT INTO `user_t` VALUES ('10', '测试1', '123456', '18');

3.2在com.ssm.pojo创建User类

package com.ssm.pojo;public class User {private Integer userid;private String username;private String password;private Integer age;public Integer getUserid() {return userid;}public void setUserid(Integer userid) {this.userid = userid;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}@Overridepublic String toString() {return "User [userid=" + userid + ", username=" + username+ ", password=" + password + ", age=" + age + "]";}}

3.3 创建Usermapper.xml和UserDao接口

UserMapper.xml

<?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.ssm.dao.UserDao" ><resultMap id="userMap" type="com.ssm.pojo.User"><id column="id" property="userid" jdbcType="INTEGER"/><result column="user_name" property="username" jdbcType="VARCHAR"/>    <result column="password" property="password" jdbcType="VARCHAR"/>    <result column="age" property="age" jdbcType="INTEGER"/></resultMap><!-- 查询所有 --><select id="getAll" resultMap="userMap">select * from user_t</select></mapper>

UserDao.java

package com.ssm.dao;import java.util.List;import com.ssm.pojo.User;public interface UserDao {public List<User> getAll();}

3.3创建UserService 和UserServiceImp

UserService.java

package com.ssm.service;import java.util.List;import com.ssm.pojo.User;public interface UserService {public List<User> getAll();}

UserServiceImp.java

package com.ssm.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.ssm.dao.UserDao;import com.ssm.pojo.User;import com.ssm.service.UserService;@Service("userService")public class UserServiceImpl implements UserService{@Autowiredprivate UserDao userDao;@Overridepublic List<User> getAll() {// TODO Auto-generated method stubreturn userDao.getAll();}}

3.4 创建控制层UserController.java

package com.ssm.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.ssm.service.UserService;@Controllerpublic class UserController {        <span><span class="annotation">@Autowired</span></span>       private UserService userService;@RequestMapping("/getAll")public ModelAndView getAll(ModelAndView mv){mv.addObject("userList",  userService.getAll());mv.setViewName("list");return mv;}}

3.4在WEB-INF/jsps/下创建list.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>        <title>userList</title>      </head>    <body>  <table border="2" align="center">      <tr>          <th>ID</th>          <th>用户名</th>          <th>密码</th>          <th>年龄</th>      </tr>    <c:forEach items="${requestScope.userList}" var="user">        <tr>            <td>${user.userid}</td>            <td>${user.username}</td>            <td>${user.password}</td>            <td>${user.age}</td>        <tr>    </c:forEach>     </table>  </body></html>

4、测试，测试之前记得改下数据库密码，在地址栏输入：http://localhost:8080/ssmtest/getAll

若出现下图，恭喜

若没有，继续努力吧，累死了。。。。。。
