Spring整合Ibatis事务实现

  最近看《Spring实战》的书，每看一章写一个简单的例子记录一下，这次是Spring事务实现，我在Spring配置文档里面通过Spring的Aop切面编程，给业务逻辑的所有方法配置了事务，使用默认的隔离和传播机制，具体是什么机制后续作答。然后测试业务逻辑方法如果遇到运行期异常是否会回滚sql语句，通过测试都符合预期。

Dao接口

package com.dao;import com.common.Person;public interface IPerson {public boolean insertPerson(Person person);}

Dao实现类

package com.dao.impl;import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;import com.common.Person;import com.dao.IPerson;public class PersonImpl extends SqlMapClientDaoSupport implements IPerson{@Overridepublic boolean insertPerson(Person person) {this.getSqlMapClientTemplate().insert("insertPerson",person);return false;}}

业务接口

package com.service;import com.common.Person;public interface IPersonService {public void testTX1(Person person);public void testTX2(Person person) throws Exception;public void testTX3(Person person) throws Exception;}

业务实现类

package com.service.impl;import com.common.Person;import com.dao.IPerson;import com.service.IPersonService;public class PersonServiceImpl implements IPersonService{IPerson personDao;public void setPersonDao(IPerson personDao) {this.personDao = personDao;}@Overridepublic void testTX1(Person person){personDao.insertPerson(person);}//测试遇到运行时异常是否RollBack@Overridepublic void testTX2(Person person) throws Exception{personDao.insertPerson(person);throw new Exception();}//测试被testTX3里面的方法是否在一个事务@Overridepublic void testTX3(Person person) throws Exception {this.testTX1(person);this.testTX2(person);}}

ibatis文档配置【sqlMapConfig.xml】

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE sqlMapConfig          PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"          "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"><sqlMapConfig><settings cacheModelsEnabled="false" enhancementEnabled="true"lazyLoadingEnabled="false" errorTracingEnabled="true"useStatementNamespaces="true" /><sqlMap resource="config/sqlmap/person.xml" /></sqlMapConfig>

具体ibatis配置【person.xml】

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE sqlMap  PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"  "http://www.ibatis.com/dtd/sql-map-2.dtd">   <sqlMap>      <typeAlias alias="person" type="com.common.Person" />            <insert id="insertPerson" parameterClass="person">         <![CDATA[            insert into person values (#id#,#name#)        ]]>      </insert>  </sqlMap>  

测试类

package test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.common.Person;import com.service.IPersonService;public class TestSpringTran {public static void main(String[] args) throws Exception {ApplicationContext context = new ClassPathXmlApplicationContext("classpath:config/spring/applicationContext.xml");Person person = new Person("1","xuxh");IPersonService personService = (IPersonService) context.getBean("personService");//这个方法会抛出异常，然后sql语句回滚personService.testTX3(person);}}
