Spring与mybatis的整合实践

今天第一次整合spring和mybatis，可谓是历程坎坷，前后历时3个小时才整合完成，各种错误加起来恐怕有几十个，尤其是导包的环节。

现在吧今天的成果贴出来，也算是对得起自己的这五个小时了，下面是整体的结构

这是spring的控制文件applicationContext.xml（悲剧的事情就是居然把有关数据的配置都放到了这里，这不是抢mybatis的饭碗吗，搞得我花了三个小时才想到！）

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsd">      <!--创建jdbc数据源 -->        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">                  <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />                   <property name="url" value="jdbc:oracle:****:@***.***.**.**:1521:*****" />                   <property name="username" value="******" />                    <property name="password" value="******" />          </bean>      <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">    <property name="dataSource" ref="dataSource" />    <property name="configLocation" value="classpath:configuration.xml" />   </bean>       <bean id="sqlSession"     class="org.mybatis.spring.SqlSessionTemplate">          <constructor-arg index="0" ref="sqlSessionFactory" />    </bean>     <bean id="customerTest" class="com.test.Test">    <!--注入SqlSessionTemplate实例 -->    <property name="sqlSessionTemplate" ref="sqlSession" />   </bean>  </beans>

这是mybatis的配置文件configuration.xml，没办法，饭碗被spring抢了，就只剩这点了

<?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="Customer" type="com.test.Customer" />        </typeAliases>        <mappers>            <mapper resource="com/test/Customer.xml" />        </mappers>    </configuration>      

这是数据映射文件customer.xml

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE mapper PUBLIC         "-//mybatis.org//DTD Mapper 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">   <mapper namespace="Customer">        <select id="selectCustomer" parameterType="int" resultType="Customer">          select * from tcor_crm_customer where CUSTID = #{id}        </select>    </mapper>  

customer的POJO类就省了，setter，getter方法，超简单，记着重写toString方法就可以了

这是测试方法

package com.test;    import org.mybatis.spring.support.SqlSessionDaoSupport;  import org.springframework.beans.factory.BeanFactory;  import org.springframework.context.support.ClassPathXmlApplicationContext;  public class Test extends SqlSessionDaoSupport{   public static void main(String[] args) {    // TODO Auto-generated method stub    new Test().firstTest();   }   public void firstTest() {    BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");    Test test = (Test)factory.getBean("customerTest");    Customer cus = (Customer)test.getSqlSession().selectOne("selectCustomer",10696);    System.out.println(cus);   }  }
