java.net.SocketException : recvfrom 실패 : ECONNRESET (동료에 의한 연결 재설정)

Question

Android에 HTTP 서버가 있습니다. 언급 된 링크에서와 같이 각 HTTP 요청에 대해 새 스레드를 만듭니다.

http://hc.apache.org/httpcomponents-core-ga/httpcore/examples/org/apache/http/examples/ElementalHttpServer.java.

나는 가끔 다음과 같이 예외를 얻고, 여러 GET 요청을 실행하면 :

난이 발생하는 이유를 모르겠습니다. 아래는 사용 된 코드이며이 예외는 handleRequest() 또는 conn.close()에서 발생합니다.

class WorkerThread extends Thread{ 
    HttpService httpService; 
    HttpServerConnection conn; 
    public WorkerThread(HttpService httpService, HttpServerConnection conn){ 
     super(); 
     this.httpService = httpService; 
     this.conn = conn; 
    }  
    public void run(){ 
     HttpContext context = new BasicHttpContext(null); 

     try { 
      Log.d(TAG,"Going to call Handle request here"); 
       this.httpService.handleRequest(this.conn, context);   
      } catch (ConnectionClosedException ex) { 
      ex.printStackTrace(); 
      Log.d(TAG,"Client closed connection exception"); 
     } catch (IOException ex) { 
      ex.printStackTrace(); 
      Log.d(TAG,"I/O exceptionnnnn " + ex.getMessage()); 
     } catch (HttpException ex) { 
      Log.d(TAG,"Unrecoverable HTTP protocol violation: " + ex.getMessage()); 
     } 
     finally { 
      Log.d(TAG,"Inside Finally Block"); 
      try {    
      this.conn.close(); 
      Log.d(TAG,"Connection closed successfully"); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }   
      } 
    } 
} 

왜 이런 일이 발생하거나 어떻게 해결할 수 있습니까? 의의 WorkerThread 클래스에서

다음 코드를 사용하여 DefaultHttpServerConnection 연결 개체를 전달 : 나는 다음과 같은 코드를 사용하여 핸들() 메서드에 DefaultHttpServerConnection 속성을 통과

Answer 1

,이 예외를하지 않았다

핸들() 메소드에서

HttpContext context = new BasicHttpContext(null); 
context.setAttribute("XXX",this.conn); 

는, 누군가를하는 데 도움이

(DefaultHttpServerConnection)context.getAttribute("XXX"); 

는 희망 사용하여 연결 개체를 얻을!
