Agent Mode in software design mode; Agent Mode in Design Mode
It seems that I have stopped the service for nearly half a month. It's really not the case. In the new year, I should keep myself at zero.
Back To Zero. Let's start from this article.
This article will introduce the basic concepts of proxy mode and the advantages and disadvantages of static proxy and dynamic proxy and how to use it (including th
Proxy is a design pattern, it provides additional access to the target object, through the proxy access to the target object, you can add additional functionality on the basis of the target object implementation, expand the function of the target object.1.Dynamic Agent1) Proxy object, do not need to implement interface;2) The generation of proxy objects is the use of JDKAPI to dynamically build proxy objects in memory (the type of interface that we specify to create a proxy object/target object
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 learning the spring framework, there is an important idea of AOP, aspect-oriented programming, using the idea of AOP combined with some of the spring's API to achieve the separation of core business and ancillary services, that is, in the execution of the core business, some ancillary business can be added, and ancillary services (such as logs, Permissions control, etc.) is generally a public business, so that the separation of the two, so that the core business code is more pure, and ancilla

Proxy mode (1) proxy mode is one of the commonly used design patterns, and the agents we use in software design generally refer to static proxies, which are explicitly specified in code.
(2) Static agent consists of two parts: Business implementation class and business proxy class. The Business implementation class is responsible for implementing the main business methods, and the business prox

JDK Dynamic Agent
A class that can only be proxied to implement an interface
A class that does not implement an interface cannot implement a dynamic proxy for the JDK

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

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

Real role: the final object to be accessed by the user, which is the real object represented by the proxy role.
