1. Forward proxy The forward proxy is located between the original server and the client, and its role is to send requests in place of the client, for example, to protect the client, or to flip the wall (the condition is that the proxy server must not be limited by GFW, currently, most VPs instances outside China are purchased.

Protocol and proxy, protocol proxy ====================================== Protocols and Proxies ====================================== [Agreement] @ Protocol [Role of the Protocol]: Specifies the interface method to be implemented.

the original object. It is usually used when the object should have different access permissions. The protection proxy checks whether the caller has the required access permissions for the request. If the caller does not have the required permissions, the proxy does not call the target object to protect the target object.2. Proxy 2.1 static

Java proxies include jdk dynamic proxies and cglib proxies. Here we only talk about jdk dynamic proxies. jdk dynamic proxies mainly use java reflection mechanisms (both java. lang. reflect packages) The principle is (examples of singers and agents ): Create a public interface, such as the Singer public interface Singer; Use a specific class to implement the interface. For example: Jay Chou, he is a Singer, so he implements the Singer class. class MySinger implements Singer Create a
