Spring與mybatis的整合實踐
今天第一次整合spring和mybatis，可謂是歷程坎坷，前后歷時3個小時才整合完成，各種錯誤加起來恐怕有幾十個，尤其是導包的環節。
現在吧今天的成果貼出來，也算是對得起自己的這五個小時了，下面是整體的結構
這是spring的控制文件applicationContext.xml（悲劇的事情就是居然把有關數據的配置都放到了這里，這不是搶mybatis的飯碗嗎，搞得我花了三個小時才想到！）
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=";
<!--創建jdbc數據源 -->
<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實例 -->
<property name="sqlSessionTemplate" ref="sqlSession" />
</bean>
</beans></span></pre>
這是mybatis的配置文件configuration.xml，沒辦法，飯碗被spring搶了，就只剩這點了
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC
"-//mybatis.org//DTD Config 3.0//EN"
";
<configuration>
<typeAliases>
<typeAlias alias="Customer" type="com.test.Customer" />
</typeAliases>
<mappers>
<mapper resource="com/test/Customer.xml" />
</mappers>
</configuration>
</span></pre>
這是數據映射文件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類就省了，setter，getter方法，超簡單，記著重寫toString方法就可以了
這是測試方法
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);
}
}</span></pre>來自：http://blog.csdn.net/thinkpadshi/article/details/8124693
