SSM框架下聲明式事務管理（注解配置方式）

一、spring-mybatis.xml文件中加入事務管理配置

<?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.xsd
http://www.springframework.org/schema/aop 
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
">

    <!-- 數據源設置 -->
    <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" />
        <!-- 自動掃描entity目錄, 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>

    <!-- 配置事務管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 注解方式配置事務 -->
    <tx:annotation-driven transaction-manager="transactionManager" />

    <!-- 攔截器方式配置事物 -->
    <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監控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>

要加入的配置代碼

 <!-- 配置事務管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 注解方式配置事務 -->
    <tx:annotation-driven transaction-manager="transactionManager" />

 

二、在調用的方法上加上@Transactional注解（必須為public方法才行,不要捕捉異常，要讓異常自動拋出，否則不能進行事務回滾。方法要寫在服務層中在controller中無效）

    @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;//產生異常 
             }else{
                 tuserMapper.insertSelective(list.get(i));
             }
         }
    }

三、測試方法（用JUnit進行測試）

@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);
    }

簡單記錄下，僅供參考。
