spring拦截器中的事务管理

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。

  3.     private int order = 1;

  29.         return service;   
  30.     }   
  31.     public void setService(EventLogService service) {   
  32.         this.service = service;   
  33.     }   
  34. }  
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。

从中可以看出,log异常拦截器在用户登录的事务回滚之前截获异常,在记录日志时,日志记录的service方法也在spring的事务管理之下,用户登录的事务还没有结束,根据REQUIRES_NEW特性,spring会新开一个事务,这时原来的数据库连接已经在一个事务中,一个连接不可能同时有两个事务,所以同时新创建一个session连接(虽然我使用了OpenSessionInViewFilter,并且session是单例的),日志记录就在新建的事务和session中进行,完了提交,并且会把新建的session连接关闭。
然后继续进行被中断的用户登录的事务管理操作,由于抛异常spring将用户登录的事务回滚。
这样能够实现预想的功能,但是如果我去掉指定的REQUIRES_NEW,那么log记录的操作会继续在用户登录的事务中进行,最后会被一起回滚。

如果我把事务管理的order设为2,log拦截器的order设为1,也就是log拦截器在事务管理拦截器的外面,会在事务管理拦截器前后执行完了再执行log的异常拦截器,打印信息如下:

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。
