Spring (17): Spring AOP (ii): Notification (front, back, return, exception, surround)

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: Surround notification, which is performed around the method.

@Before: Front-facing notifications

@After: Post Notification

@AfterRunning: Return notification

@AfterThrowing: Exception Notifications

@Around: Surround Notifications
