sslソケットマルチスレッドサーバ例外

Question

マルチスレッドサーバのためにsslソケットを作成したいが、2番目のクライアントが接続されているときにいくつかの例外が発生する。ここで

は私のサーバーのコードです：

public class Master implements Runnable{ 

    public static SSLSocket sslSocket = null; 
    public static SSLServerSocket sslServerSocket =null; 
    public static SSLServerSocketFactory sslServerSocketfactory ; 

    Master(SSLSocket s) { 
     this.sslSocket = s; 
    } 

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

    System.out.println("Listening"); 
    sslServerSocketfactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault(); 
    sslServerSocket = (SSLServerSocket) sslServerSocketfactory.createServerSocket(7777); 


    while (true) 
    { 

     sslSocket = (SSLSocket) sslServerSocket.accept(); 
     sslSocket.setEnabledCipherSuites(sslServerSocketfactory.getSupportedCipherSuites());  
     System.setProperty("javax.net.ssl.keyStore", "Master_keystore.jks"); 
     System.setProperty("javax.net.ssl.keyStorePassword", "passwd1"); 

     System.out.println("Connected"); 
     new Thread(new Master(sslSocket)).start(); 

    } 
} 
public void run() { 
    synchronized(this){ 
     do{ 
       try{  
     //here is the error 
       ObjectOutputStream objout = new ObjectOutputStream(sslSocket.getOutputStream()); 
       ObjectInputStream objin = new ObjectInputStream(sslSocket.getInputStream()); 

       /* code */ 

      } catch (Exception ex) { 
      Logger.getLogger(Master.class.getName()).log(Level.SEVERE, null, ex);} 

     }while(true); 
     } 
    } 

} 

そして、私のクライアントコードは、私が手に例外はある次

SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault(); 
SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket("localhost", 7777); 
sslsocket.setEnabledCipherSuites(sslsocketfactory.getSupportedCipherSuites()); 
System.setProperty("javax.net.ssl.keyStore", "Client_keystore.jks"); 
System.setProperty("javax.net.ssl.keyStorePassword", "passwd2"); 
try { 
     do { 
      ObjectOutputStream objout = new ObjectOutputStream(sslsocket.getOutputStream()); 
      ObjectInputStream objin = new ObjectInputStream(sslsocket.getInputStream()); 
       /* code*/ 
     } while (true); 


    } catch (Exception ex) { 
     System.out.println(ex.getMessage()); 
    } 

です：

は、誰かが私に解決策を与えることができます？

Answer 1

public static SSLSocket sslSocket = null; 

ここに問題があります。この変数を作る理由は絶対にありません。static。なぜあなたがそうしているのか正確に分からない限りstaticを使用しないでください。
