实战（五）：与spring联合使用

1. 首先对前面的工程结构做一点改变，在src_user源代码目录下建立文件夹config ,并将原来的 mybatis 配置文件 Configuration.xml 移动到这个文件夹中,

并在config 文家夹中建立 spring 配置文件：applicationContext.xml ，这个配置文件里最主要的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="false" default-autowire="byName"
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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans">
<!--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 class="org.apache.commons.dbcp.BasicDataSource" id="dataSource">
<property value="com.mysql.jdbc.Driver" name="driverClassName" />
<property value="jdbc:mysql://127.0.0.1:3306/mybatis?characterEncoding=utf8"
name="url" />
<property value="root" name="username" />
<property value="123456" name="password" />
</bean>
<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
<!--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 value="config/Configuration.xml" name="configLocation" />
</bean>
<bean class="org.mybatis.spring.mapper.MapperFactoryBean" id="userMapper">
<!--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 value="com.yihaomen.mybatis.inter.IUserOperation"
name="mapperInterface" />
</bean>
</beans>

2.然后写测试程序package com.yihaomen.test;import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MybatisSprintTest {
    private static ApplicationContext ctx;  
    static 
    {  
        ctx = new ClassPathXmlApplicationContext("config/applicationContext.xml");  
    }        
    public static void main(String[] args)  
    {  
        IUserOperation mapper = (IUserOperation)ctx.getBean("userMapper"); 
        //测试id=1的用户查询，根据数据库中的情况，可以改成你自己的.
        System.out.println("得到用户id=1的用户信息");
        User user = mapper.selectUserByID(1);
        System.out.println(user.getUserAddress()); 
        
        //得到文章列表测试
        System.out.println("得到用户id为1的所有文章列表");
        List<Article> articles = mapper.getUserArticles(1);
        
        for(Article article:articles){
            System.out.println(article.getContent()+"--"+article.getTitle());
        }
    }  
}
