Mybatis3.2和Spring3.x整合----Myb…

1.     工程主要文件

有了spring我们就不需要MybatisUtil.java了。SqlSessionFactory和SqlSession直接由spring提供。

2. 主要jar包

spring-core-3.0.0.RELEASE.jar  spring-context-3.0.0.RELEASE.jar  spring-beans-3.0.0.RELEASE.jar  spring-asm-3.0.0.RELEASE.jar  log4j-1.2.14.jar  commons-logging-1.1.1.jar  spring-expression-3.0.0.RELEASE.jar   persistence.jar spring-jdbc-3.0.0.RELEASE.jar spring-orm-3.0.0.RELEASE.jar spring-tx-3.0.0.RELEASE.jar   c3p0-0.9.1.2.jar commons-dbcp.jar commons-pool.jar jotm.jar xapool.jar   spring-aop-3.0.0.RELEASE.jar aopalliance-1.0.jar aspectjweaver-1.6.2.jar aspectjlib-1.6.2.jar aspectjrt-1.6.2.jar cglib-nodep-2.2.jar spring-aspects-3.0.0.RELEASE.jar spring-instrument-3.0.0.RELEASE.jar spring-instrument-tomcat-3.0.0.RELEASE.jar   mybatis-3.2.0.jar mybatis-spring-1.1.1.jar mysql-connector-java-3.1.13-bin.jar log4j-1.2.11.jar

除了后面的四个jar包之外其他所有jar都是通过编译器添加的。

3. 主要文件 applicationContext.xml

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" xsi:schemaLocation="http://www.springframework.org/schema/beans            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd            http://www.springframework.org/schema/context            http://www.springframework.org/schema/context/spring-context-2.5.xsd            http://www.springframework.org/schema/aop            http://www.springframework.org/schema/aop/spring-aop-2.5.xsd            http://www.springframework.org/schema/tx             http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">   class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> classpath:resources/jdbc.properties   class="org.apache.commons.dbcp.BasicDataSource"> value="${jdbc.driverClassName}" />           transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >   expression="execution(public * com.edu.mybatis_spring.dao.*.*(..))" /> advice-ref="txAdvice" />   txAdvice" transaction-manager="transactionManager">     userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean"> mapperInterface" value="com.edu.mybatis_spring.mapper.UserMapper" />

4. Mybatis-config.xml

为了配置简洁还是使用了这个配置文件，当然这些配置都是可以全都放在spring的配置文件里的。

"http://mybatis.org/dtd/mybatis-3-config.dtd">

5. UserDaoImpl.xml

package com.edu.mybatis_spring.dao.impl;   import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;   import com.edu.mybatis_spring.mapper.UserMapper; import com.edu.mybatis_spring.model.User; import com.edu.mybatis_spring.util.MybatisUtil; public class UserDaoImpl implements UserMapper {     @Override public void addUser(User user) { //UserMapper userMapper = (UserMapper) MybatisUtil.getBean(UserMapper.class); ApplicationContext ctx = new ClassPathXmlApplicationContext("resources/applicationContext.xml"); UserMapper userMapper = ctx.getBean(UserMapper.class); userMapper.addUser(user); }     @Override public User getUserByName(String username) { return ((UserMapper) MybatisUtil.getBean(UserMapper.class)).getUserByName(username); }   }

6. 结果

 

可以看到这两个方式测试通过了，我们在看数据库。

 

在数据库中看到了我们测试添加的数据。可以说整个过程是成功的。
