Spring3MVC+Mybatis快速使用

1.项目结构：

2.代码：

1.User.xml   Article.java    User.javaI    UserOperation.java：参考mybatis快速使用

2.UserController.java：请求处理

package com.spring3.controller;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.mybatis.bean.Article;import com.mybatis.service.IUserOperation;@Controller@RequestMapping("/article")public class UserController {@Autowired//类型注入IUserOperation userMapper;@RequestMapping("/list")public ModelAndView listall(HttpServletRequest requset,HttpServletResponse response){List<Article> articles = userMapper.getUserArticles(1);ModelAndView mav = new ModelAndView("list");mav.addObject("articles", articles);return mav;}}

3.Configuration.xml：可以不再导入mapper

<?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><typeAlias alias="User" type="com.mybatis.bean.User"/><typeAlias type="com.mybatis.bean.Article"/></typeAliases><environments default="development"><environment id="development"><transactionManager type="JDBC"></transactionManager><dataSource type="POOLED"><property name="driver" value="com.mysql.jdbc.Driver"/><property name="url" value="jdbc:mysql://127.0.0.1:3306/mybatis?useUnicode=true&characterEncoding=UTF-8"/><property name="username" value="root"/><property name="password" value="root"/></dataSource></environment></environments><!-- <mappers><mapper resource="com/mybatis/bean/User.xml"/></mappers> --></configuration>

4.applicationContext.xml：配置数据源、sqlsessionfactory、事务、实例化接口类mapper bean

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:p="http://www.springframework.org/schema/p"    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-4.2.xsd        http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-4.2.xsd        http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">       <!-- 加载数据库配置文件 -->        <!-- <context:property-placeholder location="classpath:/config/database.properties"/>  -->        <!-- 配置数据源 -->        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"        destroy-method="close"         p:driverClassName="com.mysql.jdbc.Driver"        p:url="jdbc:mysql:///mybatis?characterEncoding=utf8"        p:username="root" p:password="root"        p:maxActive="20" p:maxIdle="5">        </bean>        <!-- 注册事务管理 -->        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource"></property>        </bean>                <!--注册spring管理sessionfactory  -->        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <!-- 配置数据源 -->        <property name="dataSource" ref="dataSource"></property>        <!-- 指定factory配置文件 -->        <property name="configLocation" value="classpath:config/Configuration.xml"></property>        <!-- 导入所有mapper配置文件 -->        <property name="mapperLocations" value="classpath*:com/mybatis/bean/*.xml"></property>        </bean>                <!-- 通过扫描包，实例化所有的接口bean，这是一个bean集合  扫描实例化MapperScannerConfigurer        实例化调用MapperFactoryBean        注入是可使用@Autowired 类型装配-->        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <!-- 扫描包 使用分号或逗号 作为分隔符设置多于一个的包路径-->        <property name="basePackage" value="com.mybatis.service"></property>        </bean>        </beans>

5.web.xml:配置：

<?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" id="WebApp_ID" version="3.0">  <display-name>Spring3Mybatis</display-name>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list>  <!-- 加载spring配置文件 -->  <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath*:config/applicationContext.xml</param-value>  </context-param>  <!-- 启动监听加载spring容器 -->  <listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <!-- 注册servlet,加载dispatcher配置文件 -->  <servlet>  <servlet-name>mvc-dispatcher</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <load-on-startup>1</load-on-startup>  <!-- 默认加载mvc-dispatcher-servlet.xml 的servlet配置 -->  </servlet>  <servlet-mapping>  <servlet-name>mvc-dispatcher</servlet-name>  <url-pattern>/</url-pattern>  </servlet-mapping>  </web-app>

6.mvc-dispatcher-servlet.xml：驱动注解、一些全局配置

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:mvc="http://www.springframework.org/schema/mvc" 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-3.0.xsd        http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">        <!-- 包扫描,spring解析驱动 -->        <context:component-scan base-package="com.spring3.controller"></context:component-scan>        <!-- mvc注解驱动 -->        <mvc:annotation-driven/>               <!-- 静态资源控制 -->        <mvc:resources location="/WEB-INF/static" mapping="/static/**"/>        <mvc:default-servlet-handler/>               <!-- 注册请求视图处理器  前后缀配置-->        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix">        <value>/WEB-INF/pages/</value>        </property>        <property name="suffix">        <value>.jsp</value>        </property>        </bean></beans>

7.测试：

<body><c:forEach items="${articles }" var="item">${itme.id}--${item.title }--${item.content }<br/></c:forEach></body>

3.总结：

1.configuration.xml文件中的数据库配置可以不用

2.其他配置和spring+mybatis一样，唯有spring配置文件在 实例化mapper时配置略有不同，不过都是通过MapperFactoryBean去实例化接口mapper。

@Autowired类型注入
