Explain the static and dynamic agents in Java!
Agent is a design pattern In proxy pattern, one class represents the functions of another class. This type of design pattern belongs to structural pattern. In proxy mode, we create objects with existing objects to provide functional interfaces to the outside world. Purpose: to provide a proxy UTF-8...

Agent model of structured model
proxy pattern 1. What is the agent model Without changing the original class (proxy class), add some additional functions to the original class through the proxy class. Example 1: rent a house.

Spring boot learning solves the problem caused by the loss of annotations caused by the use of cglib proxy in aop in spring boot
When aop is used in spring boot, dynamic proxy will be used. If the annotation on the proxy class is obtained at this time, the acquisition will fail. For example, when using websocket, there will be problems if aop is used on the method. 1. Problem recurrence The following websocket class usesUTF-8...

A brief talk on dynamic agent
A brief talk on dynamic agent What is the agent model? Provide a proxy for other objects to control access to an object. Proxy mode is a commonly used java design mode. Its feature is that the proxy class has the same interface with the delegate class. The proxy class is mainly responsible for UTF-8...
