inside the class, and spring cannot intercept the method call.That's one step further, and spring provides us with AOP, aspect-oriented functionality. His principle and the principle of asynchronous annotations are similar:When spring starts the container, it scans the class defined by the slice. When these classes are injected, the surrogate class is injected, and when you call these methods, it is essentially the proxy class that is called.By executing the corresponding method of the parent c
