文件框架：

spring的配置文件（mybatis配置文件里面为空，全部在spring中配置，但要保留mybatis配置文件，例如添加 mybatis 拦截器时）

<?xml version="1.0" encoding="UTF-8"?><beans      xmlns="http://www.springframework.org/schema/beans"      xmlns:tx="http://www.springframework.org/schema/tx"      xmlns:p="http://www.springframework.org/schema/p"      xmlns:aop="http://www.springframework.org/schema/aop"       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/tx       http://www.springframework.org/schema/tx/spring-tx-3.0.xsd       http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">         <!-- spring读取配置文件   ，以下读取多个文件 --><bean id="common.propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="ignoreResourceNotFound" value="true" /><property name="ignoreUnresolvablePlaceholders" value="true" /><property name="fileEncoding" value="UTF-8" /><property name="locations"><list><value>classpath:jdbc.properties</value><!-- <value>classpath:log4j.properties</value> --></list></property></bean>  <!-- 配置数据源-->      <bean id="DataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">    <property name="driverClassName" value="${jdbc.driver}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /></bean>  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">      <property name="dataSource" ref="DataSource" />     <!-- 添加mybatis配置文件 -->     <property name="configLocation" value="classpath:mybatis-config.xml"></property>      <!-- 自动扫描mapping.xml文件 -->          <property name="mapperLocations" value="classpath:com.test.dao.*.xml"></property></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">          <property name="basePackage" value="com.test.dao" />          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>      </bean><!-- 单个DAO接口手动租入 <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">      <property name="mapperInterface" value="com.test.dao.UserMapper"></property>      <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>  </bean> --> </beans>

测试文件：

package com.test.test;import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.test.dao.UserMapper;import com.test.model.User;import com.test.service.UserService;public class TestUser {private UserMapper userDao; @Before    public void setUp() throws Exception { ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-commons.xml"); userDao= ctx.getBean(UserMapper.class);    }  @Test public void run(){ System.out.println("-------------------------------------"); User user = this.userDao.queryUserById(3); System.out.println(user); System.out.println("-------------------------------------"); }}

其他和mybatis整合mysql相同
