AOP proxy analysis and aop proxy I. Proxy The proxy class and the target class implement the same interface and the same method. If you use the factory mode and configuration file for management, you do not need to modify the client program. In the configuration file, configure the target class or the

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

The JDK dynamic proxy is introduced at 1.3, and its underlying need relies on a tool class Java.lang.reflect.Proxy and an interface Java.lang.reflect.InvocationHandler JDK Dynamic proxy must be agent based on interface code example:Jdkproxyutils.java Package com.my.jdkproxy; Import Java.lang.reflect.InvocationHandler; Import Java.lang.reflect.Method; Import Java.lang.reflect.Proxy; Create JDK dynamic

When it comes to proxy servers, most people should be more familiar with it. Remember when in school because the campus network can not access foreign sites, so often use agents to visit foreign sites.

According to the proxy and invocationhandler described above, it is difficult to see the advantages of this dynamic proxy. The following describes a more practical dynamic proxy mechanism. As long as we develop a software system in actual use, the same code will always repeat. In this case, the most common practice is: select the code to "copy" and "Paste" to imm

Proxy ?? Proxy refers to a person who works on behalf of others. The proxy actually uses the delegate mechanism. During the proxy process, you can do something else and then execute the code of the proxy object. Knowledge reserve 1. When to use: The gof book (see Appendix

1, forward agent (forward) is a server between the client and the original server (Origin server), in order to obtain content from the original server, the client sends a request to the agent and specifies the target (the original server), The agent then forwards the request to the original server and returns the obtained content to the client. The client must make some special settings to use the forward proxy. 2, reverse
