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

If there is such a scenario, how long does it take to count the time a method executes ? The typical idea is to record the time before the method executes, and then record it again after the method executes, to get the run time. With spring AOP, it is impossible to use only the pre-and post-methods, because they cannot share variables. This can be achieved quickly by wrapping notifications. The wrapping notification class is declared first in the Slice notification class: P

Detailed description of the non-zero surround principle when HTML5 Canvas is used to draw irregular images. html5canvas Path direction and non-zero surround PrincipleWe usually draw well-organized images. If we use a line bar to draw an abstract work, just like the figure below, how do we use fill () to dye our shoes? Here we need to use a mathematical method-the non-zero

Principle of non-zero surround rules in Canvas Non-zero surround rule: for a specified range area in a path, draw a long enough line segment from the area so that the line segment completely falls out of the path range.Non-zero surround rule counter: Then, the counter is initialized to 0. Whenever the line segment and the straight line or curve in the path inter

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

Spring AOP surround enhancement Demo I wrote a demo of pre-enhancement and post-enhancement. The pre-enhancement is the method enhancement before the method call, and the post-enhancement is the method enhancement after the method call. Surround enhancement allows the cross-cutting logic to be woven before and after the call of the target class method. It combines the functions of the front and back sides

Diligence neglect, journeys by chance ruin in the following.Create a surround notification　　Surround notification is the most powerful type of notification that allows you to write logic that wraps the target method that is being notified, and it is like writing both a pre-notification and a post-notification in a notification method.Spring uses @around annotations to declare

1) AABB bounding box: AABB bounding box is aligned with the axis of the bounding box, the simplicity of good, poor tightness (especially in the diagonal direction of the elongated shape of the object, the use of AABB, will leave a very large corner gap, resulting in a large number of not required bounding box intersection test). When the object rotates, the AABB should be rotated and updated. Once the object is deformed, it is only necessary to calculate the bounding box of the deformed basic ge

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:
