読むタイムアウトと接続タイムアウト。しかし、I/O例外は通常、接続が失われたときに発生します。しかし、ハング状況では、我々はdont'tも例外を取得します。

SchemeRegistry schemeRegistry = new SchemeRegistry(); 
schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory())); 
schemeRegistry.register(new Scheme("https", 443, SSLSocketFactory.getSocketFactory())); 

PoolingClientConnectionManager httpConnectionManager = new PoolingClientConnectionManager(schemeRegistry); 
httpConnectionManager.setMaxTotal(500); 
httpConnectionManager.setDefaultMaxPerRoute(200); 

DefaultHt‌​tpClient httpClient = new DefaultHttpClient(httpConnectionManager); 
httpClient.getParams().setParameter(ClientPNames.ALLOW_CIRCU‌​LAR_REDIRECTS, true); 

requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient); 
requestFactory.setConnectTimeout(30000); 
requestFactory.setReadTimeout(30000); 

knlogger.info(methodname,"Created requestFactory");

私が「ハング」するアプリのための1つの可能な理由を想定することができ、我々が今持っている情報量で何が起こっているかを確認するためにこれを伝えることは不可能ですが：

あなたは私をブロックし使用しています/ O。コードは、いくつかのスレッド（socketRead0のもの）で次のデータパケットを待っています。これは正常な場合もありますが、ネットワーク接続が失われている可能性が最も高いと考えられます（ルータなどのネットワークの中断など）。トランスポート層は完全に元のOSの責任であるため、アプリケーションは長い間（たとえば、キープアライブ設定時にOSがキープアライブメッセージを何度か受信できなくなるまで）、またはアプリケーション自体が送信しようとするまで接続の中断について通知されないことがあります同じソケット上のデータ

• が読み取りタイムアウトを設定する（デフォルトのJVMクラスで「タイムアウトなし」に設定されている）と維持を有効にタイムアウト
• 後に再接続：あなたは、次の解決策の一つと考えるべきで起こって、これを防止するために

  接続のために生きています（可能な場合）。接続損失の検出速度は、OSのプロトコル設定によって異なります。心拍を交換するシステムを有すること。 3つのハートビートが欠落していると、接続が失われています。

いずれにしても、接続例外を処理して再接続しようとする必要があります。
