通过 sqlSessionTemplate 整合 Spring 和 MyBatis 的方法

http://blog.csdn.net/thinkpadshi/article/details/8129034

     今天用SqlSessionTemplate持久化模板来整合spring和mybatis，其实差别不大，就是spring的配置文件里改一下，测试类改一下就可以了，如下

 

这是spring控制文件的主要内容，需要注意的就是不要忘了把sqlsession注入测试类

<span style=“font-size:14px;”>
      <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:com/Template/configuration.xml” />
      bean>

      <bean id=“sqlSession”     class=“org.mybatis.spring.SqlSessionTemplate”>
          <constructor-arg index=“0” ref=“sqlSessionFactory” />
      bean>

      <bean id=“customerTest” class=“com.Template.Test”>
          <property name=“sqlSession” ref=“sqlSession” />
      bean>span>

这是测试类，由于这是SqlSessionTemplate，所以不需要继承

“font-size:14px;”>import javax.annotation.Resource;

import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test{
    @Resource
    public SqlSessionTemplate sqlSession;

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        new Test().firstTest();
    }

    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
   }

    public void firstTest() {
        BeanFactory factory = new ClassPathXmlApplicationContext(“com/Template/applicationContext.xml”);
        Test test = (Test)factory.getBean(”customerTest”);
        Customer cus = (Customer)test.sqlSession.selectOne(”selectCustomer”,10696);
        System.out.println(cus);
    }
}

import javax.annotation.Resource;

import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test{
    @Resource
    public SqlSessionTemplate sqlSession;

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        new Test().firstTest();
    }

    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
   }

    public void firstTest() {
        BeanFactory factory = new ClassPathXmlApplicationContext("com/Template/applicationContext.xml");
        Test test = (Test)factory.getBean("customerTest");
        Customer cus = (Customer)test.sqlSession.selectOne("selectCustomer",10696);
        System.out.println(cus);
    }
}

总结：用抽象类和模板的区别就是，测试类中由于SqlSessionTemplate不需要继承，所以传值时需要手动写setter方法传值，而抽象类由于是继承的，所以自动赋值。手动赋值的时候需要特别注意的是，这里的name就是属性名，写setter方法的时候就是参照它写的，所以setter方法的命名就好办了。
