To put it simply, the forward direction

Dynamic Proxy)JDK5 is a new feature. The feature is that the agent class and its objects are dynamically created at the runtime of the program, unlike the proxy class that must be defined before compilation when we use static proxy. At runtime, the framework helps us dynamically create a proxy class that implements mul
