SSM框架下声明式事务管理（注解配置方式）

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.xsd http://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*" propagatio
e729
n="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);
}
