Spring AOP intercepts business methods and implements rights control

Difficulty: The AOP class is the common Java class, the session is unable to inject, then how to obtain the user related information in the stateful system, the session is the only way, ah, access to the session becomes very important. Thinking for a long time no way, later on the Internet to see the solution.

The idea is:

I. SYSCONTEXT member Variable Request,session,response
II. Filter to assign a value to a member in Syscontext
III. Then use the value of this syscontext in AOP

To use well, you need to understand the threadlocal and the filter execution order
