在spring里配置mybatis

     首先在spring配置proxool数据源这些不说, 我们先在src/main/resources/spring-config/下建立spring-mybatis.xml.把sqlSession放在spring容器里管理:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.1.xsd 
        http://www.springframework.org/schema/mvc         
        http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">
	<!-- 配置sqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath:test/mybabitsmapping/*.xml" />
    </bean>
    <!-- 配置扫描器 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="test.ssm.mapper" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">    
            <constructor-arg index="0" ref="sqlSessionFactory" />    
    </bean>    
</beans>

现在测试一下, 用mybatis生成工具生成如下文档:

开一个junit 测试,因为这个是脱离web环境的测试,所以之前需要手动加载proxool的连接池:

package test.testmybatis;

import java.io.File;

import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.logicalcobwebs.proxool.ProxoolException;
import org.logicalcobwebs.proxool.ProxoolFacade;
import org.logicalcobwebs.proxool.configuration.JAXPConfigurator;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import test.ssm.mapper.TaUserMapper;
import test.ssm.model.TaUser;

public class Test1 {
	ApplicationContext context ; 
	public void loadProxool() throws ProxoolException{
		try {
			// 获取配置文件句柄
			String lvsPath=Class.class.getClass().getResource("/").getPath() ;
			lvsPath=lvsPath+"../../src/main/webapp/WEB-INF/proxool.xml";
			File file = new File(lvsPath);
			//单元测试未启动web service,所以要自已加载proxool configurator
			JAXPConfigurator.configure(lvsPath, false);
			
		} catch (ProxoolException e) {
			throw e;
		}
	} 
	@Before
	public void setUp() throws Exception {
		loadProxool();
		context =new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
	}

	@After
	public void tearDown() throws Exception {
		ProxoolFacade.shutdown(0);
	}
	@Test
	public void test() {		
		org.mybatis.spring.SqlSessionTemplate lvSqlSession=(SqlSessionTemplate) context.getBean("sqlSession");
		TaUserMapper lvUserMapper= lvSqlSession.getMapper(TaUserMapper.class);		 
	    TaUser lvUserItem=lvUserMapper.selectByPrimaryKey("admin");//update from desktop
	    Assert.assertNotNull(lvUserItem);
	}

}
