Spring AOP -- Return notification, exception notification, and surround notification, springaop --
In the previous article, I learned Spring AOP and pre-notifications and post-notifications. Address: http://www.cnblogs.com/dreamfree/p/4095858.html
In this article, we will continue to learn about the previous article and continue to learn about return notifications, exception notifications, and surround noti

A pre-enhancement, post-enhanced small demo was written in front of it, and the pre-enhancement was enhanced for the method before the method call, and the post-enhancement was enhanced on the method after the method call. Surround enhancement allows the cross-cutting logic to be woven before and after the target class method invocation, which synthesizes the functions of both pre-and post-enhancement.Also continue to follow the previous code, which d
The framework used is spring mvc+springRecently want to take advantage of spring AOP surround notification to handle the Web log problem, in general, if the controller layer to make a cut, it is difficult to monitor the actual operation, in the service layer to cut into the service layer can only monitor the situation, Logging is logged by capturing the exception that is thrown by the service, which is sufficient for the current application to be logg
Surround view is a non-capturing grouping that matches other patterns based on what was before or after a pattern. Surround look is also called a 0-width assertion .Surround look includes:

ASPECTJ supports 5 types of notification annotations:
@Before: A pre-notification, executed before the method is executed;
@After: Post notification, executed after the method is executed;
@AfterRunning: Returns a notification that executes after the method returns the result (so the notification method cannot be executed when the method throws an exception);
@AfterThrowing: Exception notification, executed after the method throws an exception;
@Around:

Method One: Apply Overflow:hidden to the parent elementIn fact, the real purpose of the Overflow:hidden declaration is to prevent the inclusion element from being large by the oversize content. After applying Overflow:hidden, the containing element retains its set width, while the oversized child content is cut off by the container. In addition, Overflow:hidden has another effect, that is, it reliably forces the parent element to contain its floating child elements.Method Two: Floating the paren
