java 线程释放_java线程似乎不会被释放

發布時間：2025/3/12 编程问答 23 豆豆

生活随笔收集整理的這篇文章主要介紹了 java 线程释放_java线程似乎不会被释放小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

我沒有回答為什么第四個連接掛起,除了說這里是一個有效的代碼版本…

public class Test {

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

ServerSocket listen = new ServerSocket(9999);

ExecutorService threadPool = Executors.newFixedThreadPool(3);

while(true) {

Socket client = null;

try {

client = listen.accept();

} catch(IOException e) {

System.err.println(e);

}

System.out.println("New connection from client: " +

client.getInetAddress().getHostAddress() + "\n"

);

threadPool.execute(new ConnectionHandler(client));

}

class ConnectionHandler implements Runnable {

private Socket client;

public ConnectionHandler(Socket client) {

this.client = client;

}

@Override

public void run() {

try(BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(client.getOutputStream()))) {

String input;

while(true) {

input = in.readLine();

if(input == null)

break;

out.write(input);

out.newLine();

out.flush();

}

} catch(IOException e) {

System.err.println("Error from socket IO.");

}

try {

client.close();

} catch(IOException e) {

System.err.println("Error when closing socket.");

}

System.out.println("Client " + client.getInetAddress().getHostAddress() +

" closed connection.\n");

}

我用telnet連接,回復了一些字符并斷開連接.我這樣做了5次.
