Java Design pattern Learning 06--static agent and dynamic proxy First, the agent mode Provides an agent for an object to control access to this agent. The proxy class and the delegate class have a common parent or parent interface, so that proxy class object substitution ca

the two methods in our subject interface, which proves that when I invoke a method through a proxy object, it is actually called by the Invoke method of the handler object to which the delegate is associated, not by itself, but by proxy.This is our Java Dynamic Agent mechanism.This essay explains in detail the dynamic agent mechanism in

The previous blog is the most basic implementation of the dynamic agent principle, because it fixed the interface, fixed the proxy method, and fixed the type of Agent ,The next blog class will step into the depth introduction of the implementation of Java Dynamic Agent principle*****************************************

rent houseMethod:rentI want to rent my houseafter rent housebefore charge houseMethod:chargeYou get : 10000 RMB HouseCharge.I will get 100 RMB ProxyCharge.after charge houseProcess finished with exit code 0The output has before rent house and after rent, which shows that we can add operations before and after the method. Then look at the output I will get the RMB proxycharge. The intermediary charged a 100 block fee, stating that we can not only increase the operation, can even replace the meth

The first agent is the dynamic proxy mode of Java has been analyzed, here no longer introduced, now we first understand the next gclib agent is what? How is it implemented? What is the difference between a Java dynamic agent?Cglib (code Generation Library) is a powerful, hig

method Target.save (); The above example can be seen that the JDK dynamic proxy in the proxy object does not need to implement the interface, but the target object must implement the interface, otherwise it can not implement dynamic proxy. What is this, the problem is still there, but less. Of course, there is another dynamic proxy mode: Cglib dynamic agent. 1.2 Cglib Dynamic Agent Cglib dynamic Proxy

always have to use proxy mode for some purpose, or because of some limitations.OK, let's show you how to use proxy mode in the Java world through abstraction in a more common example.As we all know, the iphone has become a very popular mobile phone brand, some years ago even someone to buy an iphone and sell kidney, can think its brand has long been deeply rooted.The latest sale of Iphonex is also a very hot mess, so Xiao Ming students can not resist
