一、spring-mybatis.xml文件中加入事务管理配置

<?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:tx="http://www.springframework.org/schema/tx"    xmlns:aop="http://www.springframework.org/schema/aop"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">    <!-- 数据源设置 -->    <bean id="dataSource"        class="org.springframework.jdbc.datasource.DriverManagerDataSource">        <property name="driverClassName" value="${driverClassName}" />        <property name="url" value="${jdbc_url}" />        <property name="username" value="${jdbc_username}" />        <property name="password" value="${jdbc_password}" />    </bean>         <!-- myBatis文件 -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->        <property name="mapperLocations" value="classpath:xy/mapping/*.xml" />    </bean>    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="xy.dao" />        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />    </bean>    <!-- 配置事务管理器 -->    <bean id="transactionManager"        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>    <!-- 注解方式配置事务 -->    <tx:annotation-driven transaction-manager="transactionManager" />    <!-- 拦截器方式配置事物 -->    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="add*" propagation="REQUIRED" />            <tx:method name="append*" propagation="REQUIRED" />            <tx:method name="insert*" propagation="REQUIRED" />            <tx:method name="save*" propagation="REQUIRED" />            <tx:method name="update*" propagation="REQUIRED" />            <tx:method name="modify*" propagation="REQUIRED" />            <tx:method name="edit*" propagation="REQUIRED" />            <tx:method name="delete*" propagation="REQUIRED" />            <tx:method name="remove*" propagation="REQUIRED" />            <tx:method name="repair" propagation="REQUIRED" />            <tx:method name="delAndRepair" propagation="REQUIRED" />            <tx:method name="get*" propagation="SUPPORTS" />            <tx:method name="find*" propagation="SUPPORTS" />            <tx:method name="load*" propagation="SUPPORTS" />            <tx:method name="search*" propagation="SUPPORTS" />            <tx:method name="datagrid*" propagation="SUPPORTS" />            <tx:method name="*" propagation="SUPPORTS" />        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut id="transactionPointcut" expression="execution(* xy.service..*Impl.*(..))" />        <aop:advisor pointcut-ref="transactionPointcut"            advice-ref="transactionAdvice" />    </aop:config>    <!-- 配置druid监控spring jdbc -->    <bean id="druid-stat-interceptor"        class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor">    </bean>    <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut"        scope="prototype">        <property name="patterns">            <list>                <value>xy.service.*</value>            </list>        </property>    </bean>    <aop:config>        <aop:advisor advice-ref="druid-stat-interceptor"            pointcut-ref="druid-stat-pointcut" />    </aop:config></beans>

要加入的配置代码

 <!-- 配置事务管理器 -->    <bean id="transactionManager"        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>    <!-- 注解方式配置事务 -->    <tx:annotation-driven transaction-manager="transactionManager" />

二、在调用的方法上加上@Transactional注解（必须为public方法才行,不要捕捉异常，要让异常自动抛出，否则不能进行事务回滚。方法要写在服务层中在controller中无效）

    @Transactional    @Override    public void transactionalTest(List<Tuser> list) {         for(int i=0;i<list.size();i++){            /* if(i==0){                 tuserMapper.insertSelective(list.get(i));             }else{                 throw new RuntimeException();             }*/                         if(i==0){                 tuserMapper.updateByPrimaryKeySelective(list.get(i));             }else if(i==1){                 //int j=1/0;//产生异常              }else{                 tuserMapper.insertSelective(list.get(i));             }         }    }

三、测试方法（用JUnit进行测试）

@Test    public void test4(){        List<Tuser> list = new ArrayList<Tuser>();        Tuser tuser = new Tuser();        tuser.setId("0ce64eea-98d6-462b-9982-4b0816126495");        tuser.setName("name1edit");        tuser.setPwd("0");        tuser.setSjh("111");        list.add(tuser);        //int l = userService.insertSelective(tuser);        //int i=1/0;         Tuser tuser1 = new Tuser();        tuser1.setId(UUID.randomUUID().toString());        tuser1.setName("name2");        tuser1.setPwd("1");        tuser1.setSjh("222");        list.add(tuser1);        Tuser tuser2 = new Tuser();        tuser2.setId(UUID.randomUUID().toString());        tuser2.setName("name3");        tuser2.setPwd("2");        tuser2.setSjh("333");        list.add(tuser2);        //int l2 = userService.insertSelective(tuser1);        userService.transactionalTest(list);    }
