I have always had no idea how to understand the reverse direction of the reflection proxy. After Baidu knows it, I finally figured out a little bit by combining the following figure. To put it simply, the forward direction is from a LAN to the server, and the reverse direction is from the client to a LAN.
Concept:
The reverse proxy method is to u

Note: The Proxy-target-class property value determines whether an interface based or a class-based proxy is created. If the value of the Proxy-target-class property is set to True, the class based proxy will work (this requires a cglib library).

In some cases, a client does not want or cannot refer directly to an object, whereas a proxy object can act as an intermediary before the client and the

It's probably like this:
