Question

我有一个与MySQL连接的多线程服务器，每次运行它都会得到相同的异常：java.net.SocketException：Connection reset 这是我的服务器： public void run（）{ // synchronized（this）{

        try {
            serverSocket = new ServerSocket(serverPort);
            System.out.println("Server started on port " + serverPort);
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
         try{ 
             while(true){ 
                 Socket s = serverSocket.accept();
                 es.execute((Runnable) new WorkerThread(s));
                 }
         } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
             finally{ 

                     try {
                        serverSocket.close();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                 }

}

这是我的工作线程：

             String[] str = new String[10]; 
         String arr;
            try {
                int i=0;
                int b=0;
                String message=null;

            while(!Thread.currentThread().isInterrupted())   {
             message=in.readLine();

            if (message.equals("exit")){
            System.exit(0); 
            }
                       // .... here I have other if statements 
}

            } catch (IOException | SQLException e1) {

                e1.printStackTrace();
            } finally {
                try {
                    clientSocket.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                }
            }

和例外：

它出现在这里：

message=in.readLine();

Answer 1

如果使用System.exit（0）退出程序;您的连接将被终止，从而导致此异常。

如果您不希望抛出此异常，请确保在调用System.exit（0）或终止线程之前使用in.close()关闭inputstream。

退出程序时异常连接重置
