Introduce spring AOP before introducing three common proxy methods: Static agent, dynamic agent, Cglib agentAgent Overview:Proxy is a design pattern that provides additional access to the target object, which is accessed through the proxy. The benefit is that additional functionality can be enhanced based on the target object implementation. (extends the capabilities of the target object).Example: Star (Den

I found that one article is suitable.Summary: JDK's dynamic proxy is actually a combination of reflection and dynamic bytecode generated during execution; for Spring AOP, JDK dynamic proxy is also used (cglib is also used ).The following blogs are from the Internet:I.

here is simply a brief introduction to the use of the most basic agents. Agent, Popular Point said: is a person or an organization on behalf of another person or another agency to take action. In some cases, a customer does not want to or cannot refer directly to an object, and the proxy object can be End and target objects before they act as intermediaries.The proxy mode provides a

The graphical proxy settings of the new software manager are clear. Here we will introduce the network proxy settings of the terminal command line, so that you can perform apt-Get through the proxy.

Winsock provides two methods for HTTP proxy to submit HTTP requests.1. Direct Request2. Connect to the remote server and submit an HTTP request like a common request. Let's talk about the first method:Let's talk about the common process of submitting an HTTP request: After connecting to the remote server directly, submit the HTTP header to the server when the connection is successful. Check the approximate format. Get, HTTP, 1.1 Accept :*/* Accept-lan

Java reflection and dynamic proxy, java reflection dynamic proxy The two things that have been unclear are recorded today, java reflection and dynamic proxy Java reflection: 1. The ability to analyze classes at runtime 2. view the object during running 3. array operation code 4. Use the Method object In java. lang. the reflect package contains three classes: Fiel

1.Concept of forward proxy Forward proxyIsOrigin server)To get content from the original server, the client sends a request to the proxy and specifies the target (original server ), then the proxy transfers 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

1.1.view various information about the dynamic proxy classthrough the reflection mechanism can obtain Proxy creates a variety of information about the dynamic proxy class, including implemented interfaces, constructors, methods, and so on. Once you see this information, you can better understand why dynamic proxies are used. /*** @Title: proxytest.java* @Package

Dynamic proxy is such a class: it is the class generated at runtime, you must provide a set of interfaces to it when generating it, then the class declares that it implements these interfaces. Of course, you can use the class instance as any of these interfaces. Of course, this dynamic proxy is actually a proxy, it will not do substantive work for you, you must p

In the previous article, I wrote how to enable scrapy to Support HTTP proxy. But scrapy does not support socks proxy by default. Sometimes the pure HTTP proxy is easily intercepted by g f w, and proxy is required to collect websites blocked from abroad. Okay, capability is forced by demand. The following describes a s

Proxy refers to a role that represents another role to take action. Just like in life, a wine manufacturer does not directly sell wine to retail customers, they all use agents to complete their sales business. The customer does not need to look for factories to drink red wine. He only needs to find the agent of the manufacturer in the local area. The specific wine factory is there, and the customer does not need to care about it. The agent will help h

The forward proxy, the legendary agent, works like a springboard.
