This article is mainly about the rapid learning Spring Dynamic Agent principle, more Java technical knowledge, please visit the Crazy Software Education website.First, why to use dynamic proxyWhen an object or multiple objects implement the N method, there are three ways to add the object and the N methods of multiple objects to a common method, such as adding all the methods of all objects to the transaction at this time:Method One: An object one met

What is HTTP proxy: www for every person who is familiar with the internet, WWW connection request is the HTTP protocol used, so we browse the Web page, download data (also can use FTP protocol) is the use of HTTP proxy. It is usually bound to the proxy server on the 80, 3128, 8080 ports.
What is SOCKS Agent: Accordingly, the proxy server that uses SOCKS protocol is SOCKS server, it is a kind of universal proxy server. Socks is a circuit-level low-l

The following Python code captures the contents of the specified URL by urllib2, and uses a custom user-agent to prevent the site screen collector

I recently found that when I set up IE as an internet agent, "there are no pages to show" When browsing the IIS local site, I started to think that I had IIS again, and for that matter I had to reload several operating systems (really rookie ^_^), but after reloading the operating system, it still failed to solve the problem.

Agent design mode
Definition: Provides a proxy for other objects to control access to this object.
The structure of the proxy pattern is shown in the following illustration.
Dynamic proxy Use
The Java dynamic proxy mechanism realizes the design concept of Agent mode in a clever way.

That is, proxy pattern,23 one of the common object-oriented software design patterns. Proxy mode definition: 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. composition: abstract Role: A business method that declares a true role implementation through an interface or abstract class.
The main tasks to be accomplished are:
1. Periodic (periodic) backups of the database
2. Perform certain actions (work) at regular intervals
For example: The job that needs to be done is to test the database 1:00 every day, backup a copy of D:\fullbak, and name the backup database Test+yyymmdd (back up time). bak.
--Database automatic backup (SQL Server Agent-> job-> right key new job-> general inside write name and owner-> step inside code-> plan ins
proxy class Proxy and realsubject should implement the same function interface, in object-oriented programming, if you want two objects to achieve the same functionality, there are two ways:
1) Define a function interface, then the proxy class proxy and the real class Realsubject all implement this interface.
2) proxy class proxy inherits Realsubject, so proxy has the function of Realsubject, proxy can also be overridden by the method in Realsubject to achieve polymorphism.
The mechanism provide
