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!)

[html] 
<span style="font-size:14px;"><?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> 
</span> 
 

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


[html] 
<span style="font-size:14px;"><?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>  
 
 </span> 
这是数据映射文件customer.xml

[html] view plaincopy
<span style="font-size:14px;"><?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>  </span> 


 

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

[java] 
<span style="font-size:14px;">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); 
 } 

</span>
