探讨一下spring拦截器中的数据库操作和事务管理。
大家知道spring中的事务管理是通过AOP代理来实现的，对被代理对象的每个方法进行拦截，在方法执行前启动事务，方法执行完后根据是否有异常和异常的种类进行提交或回滚。 如果要在方法执行前或后或抛出异常后加上一个自己的拦截器，或者一个环绕拦截器，在拦截器中执行一些操作，比如执行一些数据库操作，记录一些信息，这些操作通过调用一个服务类的方法来执行，这个方法也在spring事务管理拦截器的管理之下，那么这个记录方法需要在另一个事务中进行，而不是与被拦截方法在同一个事务中，不然如果被拦截方法抛出异常需要回滚时，所作的记录也会被回滚，当然有时候确实需要同时回滚，那就要放在同一个事务中。 这和自己的拦截器和事务管理的拦截器的执行顺序有一定关系，spring事务管理拦截器是一个环绕通知，在被拦截方法执行前启动事务，执行后完成事务，如果自己的拦截器被spring事务管理拦截器包围在里面，那么在自己的拦截器运行时，spring已经启动了一个事务，如果你的记录信息方法需要与被拦截方法同在一个事务中，将你的记录信息方法的事务传播属性设为默认的REQUIRED就可以了； 如果你记录信息的方法需要单独的一个事务环境，那就要把事务传播属性设为REQUIRES_NEW了，这样spring事务管理器会新建一个事务，并且新建一个session连接，因为一个数据库连接不可能同时有两个事务，记录信息完了提交事务并且把新建的session连接关闭，自己的拦截器退出后继续执行被拦截的方法或它的事务处理。 相反如果自己的拦截器在spring事务管理拦截器的外面，那么记录信息的方法会在一个单独的事务中执行，并提交，不管它的事务传播属性是REQUIRES_NEW还是REQUIRED，因为与被拦截方法的事务处理没有交叉，并且可以使用同一个session连接如果是OpenSessionInViewFilter。 所以如果记录信息和被拦截方法要在不同事务中执行，分别提交，那么最好将自己的拦截器设在spring事务管理器拦截器的外面；如果需要将记录信息和被拦截方法在同一个事务中处理，必须将自己的拦截器被包围在spring事务管理拦截器中，并且记录信息方法的事务传播属性为默认的REQUIRED。 设置拦截器的执行顺序可以让拦截器处理类实现org.springframework.core.Ordered接口，在spring配置文件的AOP设置中设定自己的拦截器和spring事务管理拦截器的执行顺序，将自己的拦截的序号排在spring事务管理的前面，就可以将该拦截器放到事务管理拦截器的外面执行了，对于before通知方式会先于事务管理拦截器执行，对于after returning和after和after throwing通知方式会后于事务管理拦截器的执行，对于arount通知方式会包围事务管理拦截器执行。 下面是一个异常拦截器的例子。 有位朋友提到在spring异常拦截器中更新数据不能够提交，做了一下测试，测试环境基本是这样：一个用户登录的功能，spring对service中的每个方法进行事务管理，在用户检测的service方法上同时加上一个异常拦截器，当用户不存在或密码不正确时用户检测方法会抛出异常，异常拦截器捕获到该异常，同时记录一些日志。 spring配置文件相关： <!-- 事务管理 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 事务通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="*" propagation="REQUIRES_NEW" rollback-for="Exception"/> </tx:attributes> </tx:advice> <!-- aop代理设置 --> <aop:config proxy-target-class="true"> <aop:pointcut id="txPointcut" expression="execution(* com.hbs..*Service.*(..))"/> <aop:pointcut id="logPointcut" expression="execution(* com.hbs.customer..*Service.*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" order="1"/> <aop:aspect id="logAspect" ref="logInterceptor" order="2" > <aop:after-throwing pointcut-ref="logPointcut" method="serviceIntercept" /> </aop:aspect> </aop:config> <!-- log拦截器类 --> <bean id="logInterceptor" class="com.hbs.eventlog.EventLogInterceptor"> <property name="service" ref="logService"></property> </bean> 拦截器类： public class EventLogInterceptor implements Ordered {
private int order = 1;
private EventLogService service;
public Object serviceIntercept(ProceedingJoinPoint point) throws Throwable{
if(point instanceof MethodInvocationProceedingJoinPoint){
MethodInvocationProceedingJoinPoint mpoint = (MethodInvocationProceedingJoinPoint)point;
//
}
try {
System.out.println("记录日志开始");
service.eventLog();
System.out.println("记录日志结束");
}catch(Exception ex) {
ex.printStackTrace();
}
return null;
}
public void setOrder(int order){
this.order = order;
}
public int getOrder() {
return order;
}
public EventLogService getService() {
return service;
}
public void setService(EventLogService service) {
this.service = service;
}
}
service方法中的事务传播属性都设为要求新建事务，spring事务管理切面拦截器的order设为1，而log拦截器的order设为2，这意味着这两个要同时执行时，先执行事务拦截器，后执行log拦截器，由于事务管理是一个环绕通知（around），实际上是log拦截器被包围在事务管理拦截器中。 一个不正确的用户登录时，打印的日志： 03:35:16,562 DEBUG OpenSessionInViewFilter:253 -

Closing single Hibernate Session in OpenSessionInViewFilter 03:53:46,875 DEBUG SessionFactoryUtils:781 - Closing Hibernate Session 可以看出，用户登录的事务和日志记录的事务是前后两个不相关的事务，并且在日志记录事务中并不需要新建session连接，而是直接用在OpenSessionInViewFilter中创建的session。实际上这时也并不需要将propagation设为REQUIRES_NEW，使用默认的REQUIRES也照样能够正常工作。 所以应该将该异常拦截器设在事务管理拦截器的外面，即使用Order接口排在前面。 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。
