Dynamic proxy in Java is a powerful programming technology that allows us to dynamically generate proxy classes and objects at runtime to implement proxy operations on target objects. In dynamic proxy, the InvocationHandler interface and Proxy class are the two core components. This article will explain the concepts of InvocationHandler and Proxy in detail and provide corresponding sample code.
InvocationHandler interface
The InvocationHandler interface is one of the key interfaces of Java dynamic proxy. It defines a single method invoke()for handling method calls on proxy objects. The following is the definition of the InvocationHandler interface:
public interface InvocationHandler {
public Object invoke(Object proxy, Method method,
