The bad side of dynamic proxy ip (how dynamic proxies are implemented)

The bad side of dynamic proxy ip

Alas, partners, today I'll give you a dynamic proxy ip bad, as if we were playing hide and seek as a child, a small partner is always moving around, catching that is called a laborious ah!

First of all, we have to understand what is a dynamic proxy ip. oops, it's like a thief stealing something, he will change around, hiding in different places, running around, so that the police who catch him a good headache.

When it comes to the bad side of dynamic proxy ip, oops, just like the hide-and-seek in childhood, the little partner who moves around is always elusive, and it is hard for us to take action against him. Sometimes, dynamic proxy ip will bring hidden danger to our network security, making our network data threatened. It's like a thief stealing our precious belongings by constantly changing identities and avoiding surveillance.

How dynamic proxies are implemented

Let's talk about how to implement a dynamic agent, oops, it's as if the locks on my house have been changed by a thief, we have no idea what the thief looks like or when he will come to steal.

There are many ways to implement dynamic proxies, one of the more common is to use the Proxy class in the Java language. Through the Proxy class, we can dynamically create a proxy object, this proxy object can proxy the behavior of other objects, as if there is an outside spokesperson to replace the real stars and fans to communicate. Let me show you how dynamic proxies can be realized!

"`java
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.
import java.lang.reflect.Proxy;

public class DynamicProxyDemo {
public static void main(String[] args) {
RealSubject realSubject = new RealSubject();
InvocationHandler handler = new DynamicProxy(realSubject);
Subject subject = (Subject) Proxy.newProxyInstance(handler.getClass().getClassLoader(),
realSubject.getClass().getInterfaces(), handler);
subject.request();
}
}

interface Subject {
void request().
}

class RealSubject implements Subject {
@Override
public void request() {
System.out.println("RealSubject: Handling request.");
}
}

class DynamicProxy implements InvocationHandler {
private Object object.

public DynamicProxy(Object object) {
this.object = object;
}

@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
System.out.println("Before request handled.");
Object result = method.invoke(object, args);
System.out.println("After request handled.");
return result;
}
}
“`

Oops, seeing this code, doesn't it feel a bit like a thief sneaking into our home without our knowledge? Dynamic proxy is through a similar way to achieve the real object before and after the execution of the method to insert some of their own logic, as if we came home to an outsider, in the case of the owner does not know, for him to make some choices.

Ahem, guys, today I will give you here, I hope you can avoid the bad dynamic proxy ip, to protect our network security oh!
