java – Executors没有运行所有线程.

我正在使用Callable和Executors.我正在创建线程池：

ExecutorService executor = Executors.newFixedThreadPool(10);

当我这样做时：

executor.invokeAll(taskList);

在10个线程中,仅从轮询中获取了1个线程.我只打印了这个：

The current thread is pool-1-thread-1

但我希望应该有10个类似的println语句.

这是完整的代码：

import java.util.concurrent.Callable;
import java.util.List;
import java.util.ArrayList;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.TimeoutException;
import java.util.concurrent.Future;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.CompletionService;
import java.util.concurrent.ExecutorCompletionService;

public class Parallel
{
    public static void main(String args[])
    {
        Learning l = new Learning();
        l.message = "1st Object";
        l.testThread();
    }
}

//this class deals with threads
class Learning
{

    public String message;

    public void setMessage(String message)
    {
        this.message = message;
    }

    //contains the code where
    public void testThread()
    {

       //create a callable for each method
       Callable<String> callable1 = new Callable<String>()
       {
          @Override
          public String call() throws Exception
          {
             System.out.println("The current thread is " + Thread.currentThread().getName());
             return method1();
             // return null;
          }
       };


       //add to a list
       List<Callable<String>> taskList = new ArrayList<Callable<String>>();
       taskList.add(callable1);

       //create a pool executor with 10 threads
       ExecutorService executor = Executors.newFixedThreadPool(10);


       try
       {
         List<Future<String>> futureList = executor.invokeAll(taskList);

       }
       catch (InterruptedException ie)
       {
       }
    }

    //put your code here!
    private String method1()
    {
        return Thread.currentThread().getName();
    }
}

我在这里错过了什么吗？
