1. The overall purpose of the agency : to expand the functions of the target object. Does not change its own function;
2. Common proxy modes : static, dynamic, Cglib proxy. The first two are suitable for the target object that implements the interface, and the latter is suitable for the target object that does not implement the interface;
3. The proxy idea of the target object with interface: Based on the idea of copy + extension, create a proxy class: In order to better expand on the original basis, the proxy class and the target class can realize the same interface (similar to copy, then Expand);
4. Based on different "copy" methods, it is divided into static and dynamic agents : the following are mainly used for understanding and memory, and the specific code refers to the article.
- The static is as follows:
- The dynamics are as follows:
Skip generating proxy classes and directly generate proxy objects.
