(java)socket全双工长连接通信实例

（借鉴备忘）直接上代码：

client：

import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.io.Reader;
import java.net.Socket;
import java.nio.CharBuffer;

public class TestSocketClient {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new TestSocketClient().start();
	}
	class SendThread extends Thread{
		private Socket socket;
		public SendThread(Socket socket){
			this.socket=socket;
		}
		@Override
		public void run(){
			while(true){
				try{
					Thread.sleep(1000); 
					String send=""+System.currentTimeMillis()+"";
					PrintWriter pw=new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
					pw.write(send);
					pw.flush();
				}catch(Exception e){
					e.printStackTrace();
				}
			}
		}
	}
	class ReceiveThread extends Thread{
		private Socket socket;
		public ReceiveThread(Socket socket){
			this.socket=socket;
		}
		@Override
		public void run(){
			while(true){
				try{
					Reader reader=new InputStreamReader(socket.getInputStream());
					CharBuffer charbuffer=CharBuffer.allocate(8192);
					int index=-1;
					while((index=reader.read(charbuffer))!=-1){
						charbuffer.flip();//设置从0到刚刚读取到的位置
						System.out.println("client:"+charbuffer.toString());
					}
				}catch(Exception e){
					e.printStackTrace();
				}
			}
		}
	}
	public void start(){
		try{
		Socket socket=new Socket("127.0.0.1",18889);
		new SendThread(socket).start();
		new ReceiveThread(socket).start();
		}catch(Exception e){
			e.printStackTrace();
		}
		
	}
}

server:

import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.io.Reader;
import java.io.Writer;
import java.net.ServerSocket;
import java.net.Socket;
import java.nio.CharBuffer;
import java.util.Date;

public class TestSocketServer {

	private final static String SOAP_BEGIN = "1024*16){
						break;
					}
				}
			}catch(Exception e){
				e.printStackTrace();
			}finally{
				if(socket!=null){
					try{
						if(!socket.isClosed()){
							socket.close();
						}
					}catch(Exception e){
						e.printStackTrace();
					}
				}
			}
		}
	}
