Then the agent will always know what the agent (Real customer) can do and what it cannot do, that's two people.Same interfaceAlthough the agent cannot work, the agent can work.

Therefore, the running on the server is called dynamic, and the opposite is static. Static resources can be returned to the client intact. The web server page consists of many resources. Each resource requires a separate request from the browser. The Browser needs multiple requests to load the resource locally. The server shoul

You can extend the target function without modifying the function of the target object.2. Disadvantages: Because the proxy object needs to implement the same interface as the target object, there are many

proxy object itself, and the delegate proxy is set to the proxy property pointer pointing to the proxy object, it is equivalent that the proxy object only calls its own method in the delegate. If the method is not implemented, it will cause a crash. From the crash informati

This is actually the meaning of Before and After notifications in AOP. Add the t

A friend of yours asked this question today.Talk for a long, do not understand. At that time, I gave an example: all the computers in our company internal domain to go to the external network, is to go through a computer, he can control we can not mess up some sites, so that we can not go to work on some entertainment, video site, this server is a common agent, that is, the forward proxy. (The famous gfw!!! ）The client wants to visit our company's web

The way to implement the proxy is to install the proxy Server software on the server, so that it becomes a proxy server, open source software is more popular is squid and nginx.First, the forward agentA forward proxy is a server between client A and the original Server B, in order to get content from the server, the us

Java: static proxy and dynamic proxy, java static and dynamic The proxy mode is a common design mode. It features that the proxy class has the same interface as the delegate class. In specific implementation, there are static proxy and dynamic

[Java] 13: proxy mode-dynamic proxy! In the previous blog, we talked about a form of proxy mode-static proxy. At the end of this article, we mentioned the shortcomings of static proxy, one of them is that when there are many business classes, it is obviously a very bad choic

AOP is one of the core of the spring framework, and it plays a very important role in the application and is the foundation of other components of spring. It is a facet-oriented programming idea. On the basic knowledge of AOP, I believe most of the children's shoes are already at hand, we skip this part to explain the underlying implementation mechanism of the core functions of AOP: How to use dynamic proxy to achieve cut-plane interception. The block
