可以从另一个插件调用重写的方法吗？

Question

I'm coding two plugins for a program, one of this plugin is a "library plugin" and contains a lot of classes used by the other plugins, the other is one of the plugin based on this library. All works well except one thing. In my library plugin I wrote a socket class sintetized to this:

public class MServerSocket {
    public void initServer(int port) {
        //Code to receive message from client
        execute(input, clientOutput);
    }

    public void execute(String input, DataOutputStream clientOutput) {
        System.out.println(input);
        send(clientOutput, input);
    }

    public void send(DataOutputStream clientOutput, String output) {
        //Code to send message to client
    }
}

In the other plugin I extend this class and override the execute method to do something, like this:

public class MySocketServer extends MServerSocket {
    @Override
    public void execute(String input, DataOutputStream clientOutput) {
        //Do something
        MServerSocket.send(clientOutput, input)
    }
}

Now my second plugin should override my library plugin class but it doesn't. In the second plugin I call it in the main like this:

public class Main {
    public void onEnable() { //method called to load plugin
        private static MServerSocket socket = new MServerSocket();
        socket.initServer(12980);
    }
}

When I send a socket message to my socket it is printed to the console as said in the library execute method.

So here I am, can someone give me an answer and possibly a solution? Thanks in advance

Answer 1

Your code currently constructs a MServerSocket object but if you want the behaviour of your MySocketServer to be executed, you need to construct one of those.

You should also change (at a minimum):

MServerSocket.send(clientOutput, input)

...to

super.send(clientOutput, input)

...as that's the proper way to delegate to a method from the parent class.
