Java static proxy instance analysis

Explanation

1. If the agent already exists before the program is run, then this agent method becomes a static agent.

In this case, the proxy is usually defined by us in Java code.

2. Generally speaking, the proxy class and the delegate class in the static proxy will implement the same interface, or generate the same parent class.

Example

/**
 * 委托类和代理类都实现了Sell接口
 */
public interface Sell {
    void sell();
    void ad();
}
