1.所用到的jar包，千万别少，否则报错。

2.重点的配置文件：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" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="  
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

  <!--本示例采用DBCP连接池，应预先把DBCP的jar包复制到工程的lib目录下。 --> 
 
  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 
     <property name="url" value="jdbc:mysql://127.0.0.1:3306/mybatis?characterEncoding=utf8"/> 
     <property name="username" value="root"/> 
     <property name="password" value="password"/> 
  </bean> 
 
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 
     <!--dataSource属性指定要用到的连接池--> 
     <property name="dataSource" ref="dataSource"/> 
     <!--configLocation属性指定mybatis的核心配置文件--> 
     <property name="configLocation" value="config/Configuration.xml"/> 
  </bean> 
 
  <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean"> 
     <!--sqlSessionFactory属性指定要用到的SqlSessionFactory实例--> 
     <property name="sqlSessionFactory" ref="sqlSessionFactory" /> 
     <!--mapperInterface属性指定映射器接口，用于实现此接口并生成映射器对象--> 
     <property name="mapperInterface" value="com.mybatis.interfaces.IUserOperation" /> 
  </bean> 
 
</beans>

建一个测试类进行测试：

package com.mybatis.test;
import com.mybatis.model.*;
import com.mybatis.interfaces.*;
import java.util.List; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class myBatisSpringTester {

	private static ApplicationContext ctx; 
	static { 
		ctx = new ClassPathXmlApplicationContext("config/applicationContext.xml"); 
	} 
	
	public static void main(String[] args) 
	{ 
		IUserOperation mapper = (IUserOperation)ctx.getBean("userMapper"); 
	    User user = mapper.selectUserByID(24); 
	    System.out.println(user.getUserAddress()); 
	    List<Article> articles = mapper.getUserAticles(24); 
	    for(Article article:articles){ 
	    	System.out.println(article.getContent()+"--"+article.getTitle()); 
		} 
	}
}
