原理：当多个客户端对服务器发起请求时。使用线程池管理服务端阻塞解除后(开始通讯)对业务处理逻辑频繁开启新的任务线程。

public class Server {	final static int PORT = 8765;	public static void main(String[] args) {		ServerSocket server = null;		BufferedReader in = null;		PrintWriter out = null;		try {			server = new ServerSocket(PORT);			System.out.println("server start");			Socket socket = null;			HandlerExecutorPool executorPool = new HandlerExecutorPool(50, 1000);			while(true){				socket = server.accept();				executorPool.execute(new ServerHandler(socket));			}					} catch (Exception e) {			e.printStackTrace();		} finally {			if(in != null){				try {					in.close();				} catch (Exception e1) {					e1.printStackTrace();				}			}			if(out != null){				try {					out.close();				} catch (Exception e2) {					e2.printStackTrace();				}			}			if(server != null){				try {					server.close();				} catch (Exception e3) {					e3.printStackTrace();				}			}			server = null;						}	}}

线程池配置如下：

采用无界队列的方式创建自定义线程池

public class HandlerExecutorPool {	private ExecutorService executor;	public HandlerExecutorPool(int maxPoolSize, int queueSize){		this.executor = new ThreadPoolExecutor(				Runtime.getRuntime().availableProcessors(),				maxPoolSize, 				120L, 				TimeUnit.SECONDS,				new ArrayBlockingQueue
    
     (queueSize));	}		public void execute(Runnable task){		this.executor.execute(task);	}			}
