mybatis与spring整合事务管理

1.最重要的spring配置文件

<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>${driverClassName}</value>
</property>
<property name="password">
<value>${password}</value>
</property>
<property name="username">
<value>${username}</value>
</property>
<property name="url">
<value>${url}</value>
</property>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis.xml" />
<property name="plugins">
<array>
<ref bean="pagePlugin" />
</array>
</property>
<property name="mapperLocations">
<list>
<!-- 事务配置 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<aop:config>
<aop:pointcut
expression="execution(public * com.test.service.*.*(..))"
id="pointcutExtend" />
<aop:pointcut
expression="execution(public * com.test.frame.service.impl.*.*(..))"
id="pointcutBase" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcutExtend" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcutBase" />
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="query*" propagation="REQUIRED" read-only="true" />
<tx:method name="expand*" propagation="REQUIRED" read-only="true" />
<tx:method name="save*" propagation="REQUIRED"  rollback-for="Exception"/>
<tx:method name="insert*" propagation="REQUIRED"  rollback-for="Exception" />
<tx:method name="delete*" propagation="REQUIRED"  rollback-for="Exception"/>
<tx:method name="update*" propagation="REQUIRED"  rollback-for="Exception"/>
</tx:attributes>
</tx:advice>

service中方法：

public String insertEntity(BaseEntity entity) throws Exception {
if (null == entity.getId() || "".equalsIgnoreCase(entity.getId())) {
entity.setId(CreateUuid.getID());
}
this.dao.insertEntity(entity);
int i=1/0;//测试spring事务
return entity.getId();
}

注意事项：

//1.直接<aop:pointcut

/*expression="execution(public * com.test.service.*.*(..))"

id="pointcut" />

达不到事务的目的，必须

<aop:pointcut

expression="execution(public * com.ssm.core.frame.service.impl.*.*(..))"

id="pointcut1" />

才可以，如果在子类ProviderServiceImpl中的方法可以使用上面第一句话来进行事务控制。一遍情况下子类为空，用的都是继承的BaseService中方法，只切面子类ProviderServiceImpl是不行的。

*/

测试代码：

Provider provider4 = new Provider();
//ProviderID,BH,MC,LXR,DH,DZ,YX,CZ,BZ1,BZ2
//provider4.setId(CreateUuid.getID());
provider4.setBh("bh4");
provider4.setMc("mc4");
provider4.setLxr("lxr4");
provider4.setDh("dh4");
provider4.setDz("dz4");
provider4.setYx("yx4");
provider4.setCz("cz4");
provider4.setBz1("bz1");
provider4.setBz2("bz2");
String insertResult4 = providerService.insertEntity(provider4);

正确输出日志为：

注意日志中的有关事务的描述。

假如事务没起作用，比如pointcut指向的类不对，那么日志信息为：

DEBUG 2016-03-03 21:13:57,732 org.mybatis.spring.SqlSessionUtils.main Creating a new SqlSession

注意日志信息中的Closing non transactional SqlSession ，表明这个是没有事务控制的，因此可以成功插入记录，而没有进行回滚。
