How to use Java dynamic proxy?

1. When using dynamic proxy, you need to define an intermediary class between the proxy class and the delegate class.

This intermediary class is required to implement the InvocationHandler interface.

/**
 * 调用处理程序
 */
public interface InvocationHandler {
    Object invoke(Object proxy, Method method, Object[] args);
}

2. In dynamic proxy mode, the delegate class must implement a certain interface.

public class Vendor implements Sell {
    public void sell() {
        System.out.println("In sell method");
    }
 
    public void ad() {
        System,out.println("ad method");
    }
}
