客户端：

package cn.luobida.serviceclient;



import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.net.Socket;



public class ServiceClient {

	

	public static void main(String[] args) throws Exception {

		Socket socket = new Socket("localhost", 8899);

		InputStream inputStream = socket.getInputStream();

		OutputStream outputStream = socket.getOutputStream();

		

		OutputStreamWriter writer = new OutputStreamWriter(outputStream);

		writer.write("hello");

		writer.flush();

		

		BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

		String line = reader.readLine();

		System.out.println(line);

		

		inputStream.close();

		outputStream.close();

		socket.close();

		

	}

}

服务端：

package cn.luobida.serviceserver;



import java.net.InetSocketAddress;

import java.net.ServerSocket;

import java.net.Socket;



public class ServiceServer {

	

	public static void main(String[] args) throws Exception {

		ServerSocket server = new ServerSocket();

		server.bind(new InetSocketAddress("localhost", 8899));

		

		while(true){

			Socket socket = server.accept();

			new Thread(new ServiceServerTaskImpl(socket)).start();

		}

	}

}

任务处理类：



package cn.luobida.serviceserver;



import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.net.Socket;

import java.nio.CharBuffer;



public class ServiceServerTaskImpl implements Runnable{

	

	Socket socket;

	InputStream inputStream = null;

	OutputStream outputStream = null;

	

	public ServiceServerTaskImpl(Socket socket){

		this.socket = socket;

	}

	

	

	public void run() {

		try {

			inputStream = socket.getInputStream();

			outputStream = socket.getOutputStream();

			InputStreamReader isr = new InputStreamReader(inputStream);	

					

			BufferedReader buf = new BufferedReader(new InputStreamReader(inputStream));

			String line = buf.readLine();

			System.out.println(line);

			

			String string = matchmess(line);

			

			

			OutputStreamWriter writer = new OutputStreamWriter(outputStream);

			writer.write(string);

			writer.flush();

		} catch (Exception e) {

			e.printStackTrace();

		} finally{

			try {

				inputStream.close();

				outputStream.close();

				socket.close();

			} catch (Exception e) {

				e.printStackTrace();

			}

		}

		

	}



	private String matchmess(String line) throws Exception {

		if(line.equals("hello,myname is luobida.")){

			return "i recive ,luobida";

		}

		return "erro";

		

	}
