Webサービスリターン実行後に終了するスレッド？ここ

Question

私の問題は、スレッドが（ない日付値まで）、その値を更新する前に、Webサービスが認識クラスの静的変数の応答の値を返すということです は、私のWebサービスです：

@GET 
     @Produces("application/json") 
     public synchronized String returnTitle() { 
      String result="init value"; 
      Recognition recognition = new Recognition(); 
      FutureTask<String> future = new FutureTask(recognition); 
      future.run(); 
      System.out.println("result0 = "+result); 
      try{ 
       System.out.println("result = "+result); 
      result = future.get(); 
      System.out.println("result1 = "+result); 
      }catch (Exception e){e.printStackTrace();} 

      return "<h1>hello</h1> "+ Recognition.response; 
     } 

このクラスWebサービスから返されるresponseという静的変数が含まれています。

import java.io.File; 
import java.util.List; 
import java.util.concurrent.Callable; 
import com.bitsinharmony.recognito.MatchResult; 

public class Recognition implements Callable<String>{ 

public static String response =""; // The variable to return by the web service. 


@Override 
public String call() throws Exception { 
    response= ""; 
    if (!Ressources.isInitilalized){ // if the initialization of training data is not done yet. 
     Ressources.init();   // initialize training data 
     Ressources.isInitilalized= true; //changing the boolean variable to know that inisialization has been done next execution 
    } 
     final JavaSoundRecorder recorder = new JavaSoundRecorder(); // Class used to record voice from microphone and save it to .wav file. 

       Thread stopper = new Thread(new Runnable() { // Thread that sleeps 5000 ms then stops recording. 
        public void run() { 
         try { 
          Thread.sleep(5000); 
         } catch (InterruptedException ex) { 
          ex.printStackTrace(); 
         } 
         recorder.finish(); // after timer finished stop recording 

         try{ 
          File file20 = new File("C:\\RecordAudio.wav"); 

          List<MatchResult<String>> matches = Ressources.recognito.identify(file20); 

          MatchResult<String> match = matches.get(0); 
          //file20.delete(); 

          System.out.println(match.getKey() + " " + match.getLikelihoodRatio()); 


         response = match.getKey()+" "+match.getLikelihoodRatio()+"\n";// say for which user the sound recorded belongs with witch probability. 
         }catch (Exception e){} 
        } 
       }); 

       stopper.start(); // start the thread 

       // start recording 
       recorder.start(); // start recording 

    return response; 
} 

} 

このクラスは、話者識別のモデルを訓練するために、静的なリソースが含まれています。

そして最後に、このクラスは、音声を録音し、.wavファイルにそれを保存するために使用されます。

      line.open(format); 
      line.start(); // start capturing 

      // System.out.println("Start capturing..."); 

      AudioInputStream ais = new AudioInputStream(line); 

     // System.out.println("Start recording..."); 

      // start recording

    */ 
    public void finish() { 
     line.stop(); 
     line.close(); 
     // System.out.println("Finished"); 
    } 

} 

Answer 1

多分静的変数を初期化するだけです。変数の初期化と宣言 は同じではありません。

• は初期化：int a = 0;
• を宣言：int a;

を、これはあなたが探しているものでない場合は、多分あなたは、もう少し具体的かもしれませんエラーメッセージを表示する
