First, the agent modeProxy mode is a common Java design pattern, characterized by proxy class and delegate class have the same interface, Agent class is mainly responsible for the delegation class preprocessing messages, filtering messages, forwarding messages to the delegate class, and afterwards processing messages.There is usually an association between a proxy class and a delegate class, the object of a
What is a static proxy.
As is known in the week, there is a proxy pattern in the 23 commonly used design patterns. It is defined as follows:
Provides a proxy for other objects to control access to this object. In some cases, an object may not fit or directly refer to another object, and the proxy object can act as a mediator between the client and the target object.
The idea of Agent mode is to insert a proxy object between the actual object and the

In java design patterns, a design pattern is very important, namely the proxy pattern. The proxy pattern generally involves the role

Problem Description::I now have a tricky problem, to save the object through the spring managed service class, which is obtained through reflection, and it is experimentally discovered that the class can only reflect the method that Sservice implements the interface, and the methods of the extends class do not appear. Debug found that this Servie instance was replaced by spring with the Jdkdynmicproxy class, rather than the original object, it is only the service inherited interface method, and

Generally, the following steps are required for proxy:
1. Develop an agreement. The protocol can be declared in. h of the delegate object, or in a separate. h. After the protocol is developed, the method that requires proxy objects is declared in the Protocol.
2. Set proxy properties. After the protocol is set, you need to set a proxy attribute for the delegate

The concept of an agent: a simple understanding is that by creating a proxy object for an object, we do not directly reference the original object, but rather the proxy object created to control the reference to the original object.Dynamic Proxy: refers to the dynamic generation of the Java reflection mechanism when the program is running, without having to write code manually. Dynamic proxies not only simplify programming, but also improve the scalab
