Definition of proxy mode: Provide a surrogate or placeholder for another object to controlaccess to it (Provides a proxy for other objects to control access to this object.). Create a proxy object in proxy mode to allow the proxy object to control access to the target object (the target object can be a remote object, an overhead object can be created, or an object requiring security control ), in addition, some additional functions can be added without changing the target object.

Here we record the static proxy, UML class diagram:

Public interface Subject {public void operatetion ();}

 

Public class RealSubject implements Subject {@ Override public void operatetion () {// core business Implementation }}

 

Public class Proxy implements Subject {private Subject subject; public Proxy (Subject subject) {this. subject = subject ;}@ Override public void operatetion () {doSomeThing (); // enhance the business subject. operatetion (); doSomeThing ();} private void doSomeThing (){}}

 

The static proxy mode is simple and clear at a glance.
