java制作socket的客户端和服务器

问题背景：在win7上安装了ubuntu的虚拟机，mac的虚拟机，现在需要在win7上直接调用ubuntu或mac系统中的shell脚本，因此使用socket来解决

问题解决方案：在win7上运行socket的客户端，在ubuntu或mac系统中运行socket服务器

下面贴出我的代码，并做简单的解释

socket客户端

SocketClient.java

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class SocketClient {
    public static final String ANDROIDIP = "192.168.26.131";
    public static final String IOSIP = "192.168.26.132";
    public static final String SYMBIANIP = "127.0.0.1";
    
    public static final String ANDROIDCMD = "A";
    public static final String IOSCMD = "I";
    public static final String SYMBIANCMD = "S";
    
    public static final int SOCKETPORT = 8888;
    
    static Socket socket;
    BufferedReader in;
    PrintWriter out;
    
    public SocketClient(String sendCommand)
    {
        try{
            if(sendCommand.equals(ANDROIDCMD))
            {
                socket = new Socket(ANDROIDIP,SOCKETPORT);
            }
            else if(sendCommand.equals(IOSCMD))
            {
                socket = new Socket(IOSIP,SOCKETPORT);
            }
            else if(sendCommand.equals(SYMBIANCMD))
            {
                socket = new Socket(SYMBIANIP,SOCKETPORT);
            }
            
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream(),true);
            out.println(sendCommand);
            
            System.out.println(sendCommand);
            
        }catch(Exception e)
        {
            return;
        }
    }
    

}

CompileClient.java

public class CompileClient {

    public static void main(String[] args)  {
        new SocketClient(SocketClient.ANDROIDCMD);
        System.out.println("compile client start");
    }
}

socket服务端(以客户端发送A命令为例)

SocketServer.java

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketServer implements Runnable{
    public static final int SERVERPORT = 8888;
    public String acceptedCommand= null;
    public static final String command = "A";

    @Override
    public void run() {
        ServerSocket serverSocket = null;
        
        try {
            serverSocket = new ServerSocket(SERVERPORT);
        } catch (IOException e) {
            e.printStackTrace();
            return;
        }

        
        while (true){
            Socket socket = null;
            
            try {
                
                socket = serverSocket.accept();
                BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                acceptedCommand = in.readLine();
                
                System.out.println(acceptedCommand);
                
                if(acceptedCommand.equals(new String(command)))
                {
                    System.out.println("run android.sh script");
                    Runtime.getRuntime().exec("/home/whb/android.sh");
                }
                
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        
        
    }
    

}

CompileServer.java

public class CompileServer {

    public static void main(String[] args) {
        Thread socketServerThread = new Thread(new SocketServer());
        socketServerThread.start();
        System.out.println("compile server start");
    }

}

其中ip地址可通过ifconfig获得

port至少打于1024，可通过netstat获得已经使用的端口
