Httpclient 4.5.x Multi-Thread-Anforderungsfehler: wurde aus diesem Pool nicht geleast

Question

Ich schreibe eine Testprobe für Httpclient von Apache-Httpclient des Multi-Thread-Anforderungsfehler zu testen.

Ich lief es in einer for-Schleife und 2 Fäden in jeder Schleife erstellen, um die Testfälle mit 2 unterschiedlichen Hosts laufen Einstellung Manager zu bündeln.

In 10 Schleifen, ich immer konfrontiert 1 Fehler als: Ausnahme im Thread "Thread-2" java.lang.IllegalStateException: Eintrag [ID: 17] [Route: {} -> http: // *** : 8000] [state: null] wurde nicht von diesem Pool geleast bei org.apache.http.util.Asserts.check (Asserts.java:46)

Hat mein Code ein Problem? Was soll ich machen?

Die Probe ist unter:

private void testHttpClient() { 

     HttpHost proxy = new HttpHost("dev.host.com", 8001); 
     final DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy); 

     final PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(); 
     cm.setMaxTotal(20); 
     cm.setDefaultMaxPerRoute(1); 
     HttpHost localhost1 = new HttpHost("dev.test1.com", 8001); 
     cm.setMaxPerRoute(new HttpRoute(localhost1), 2); 
     HttpHost localhost2 = new HttpHost("dev.test2.com", 8000); 
     cm.setMaxPerRoute(new HttpRoute(localhost2), 2); 

     RequestConfig requestConfig = RequestConfig.custom() 
      .setConnectTimeout(1000) 
      .setSocketTimeout(1000) 
      .setConnectionRequestTimeout(1000) 
      .build(); 
     final CloseableHttpClient httpclient1 = HttpClients.custom() 
      .setConnectionManager(cm) 
      .setRoutePlanner(routePlanner) 
      .setDefaultRequestConfig(requestConfig) 
      .build(); 

     RequestConfig requestConfig2 = RequestConfig.custom() 
      .setConnectTimeout(1000) 
      .setSocketTimeout(1000) 
      .setConnectionRequestTimeout(1000) 
      .build(); 
     final CloseableHttpClient httpclient2 = HttpClients.custom() 
      .setConnectionManager(cm) 
      .setRoutePlanner(routePlanner) 
      .setDefaultRequestConfig(requestConfig2) 
      .build(); 

     class HttpClientThead1 implements Runnable { 
      public void run() { 
      for (int i = 1; i <= 1; i++) { 
       System.out.println("HttpClientThead1 Start"); 
       HttpClientContext context = HttpClientContext.create(); 
       try { 
       HttpGet httpget = new HttpGet("http://dev.test1.com:8001/test/id/10001"); 
       CloseableHttpResponse response = httpclient1.execute(httpget, context); 
       long t = System.currentTimeMillis(); 
       System.out.println("HttpClientThead1 " + i + ":" + response.getEntity().toString() + " " + t); 
       response.close(); 
       } catch (ClientProtocolException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
       } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
       } finally { 
       cm.closeExpiredConnections(); 
       cm.closeIdleConnections(30, TimeUnit.SECONDS); 
       } 
      } 
      } 
     } 

    class HttpClientThead2 implements Runnable { 
     public void run() { 
     for (int i = 1; i <= 1; i++) { 
      System.out.println("HttpClientThead2 Start"); 
      HttpClientContext context = HttpClientContext.create(); 
      try { 
      HttpGet httpget2 = new HttpGet("http://dev.test2.com:8000/test/id/10002"); 
      CloseableHttpResponse response2 = httpclient2.execute(httpget2, context); 
      long t = System.currentTimeMillis(); 
      System.out.println("HttpClientThead2 " + i + ":" + response2.getEntity().toString() + " " + t); 
      response2.close(); 
      } catch (ClientProtocolException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
      } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
      } finally { 
      cm.closeExpiredConnections(); 
      cm.closeIdleConnections(30, TimeUnit.SECONDS); 
      } 
     } 
     } 
    } 

    for (int j = 1; j <= 10; j++) { 
     HttpClientThead1 t1 = new HttpClientThead1(); 
     HttpClientThead2 t2 = new HttpClientThead2(); 

     Thread thread1 = new Thread(t1); 
     Thread thread2 = new Thread(t2); 
     thread1.start(); 
     thread2.start(); 
    } 
} 

Answer 1

Ich bekam die Antwort, weil ich einen Proxy in dieser Httpclient gesetzt. Also muss ich es auch in setMaxPerRoute mit den Proxy-Informationen setzen.

So sollte es sein: cm.setMaxPerRoute (neue HttpRoute (localhost2, Proxy), 10);
