ThreadPoolExecutor 线程池使用

public abstract class AbsBaseProvider {



    private final BlockingQueue<Runnable> workQueue = new LinkedBlockingQueue<Runnable>();



    private final ThreadPoolExecutor mThreadPool = new ThreadPoolExecutor(5, 20, 20, TimeUnit.SECONDS, workQueue);



 



   



  



    protected synchronized void loadData(DataContext dc, String url) {

        mThreadPool.execute(new OTGInteractive(dc, url));

        mThreadPool.shutdown();



        // new Thread(new Interactive(dc, url)).start();



    }







   



    private class Interactive implements Runnable {



        private final DataContext dc;



        private final String url;



        public OTGInteractive(DataContext dc, String url) {

            this.dc = dc;

            this.url = url;

        }



        @Override

        public void run() {

         

                    try {

                        System.out.println("test…...");

                    } catch (Exception e) {



                        if (e instanceof AppException) {



                        }

                        else {



                        }

                        if (mListener != null) {

                            mListener.onServerError();

                        }

                        sLogger.e("error", e.toString());

                        e.printStackTrace();

                    }

                

            });



        }



    }



  

}

以上是定义的线程池类

使用时

的问题就是同一个AbsBaseProvider对象只能调用一次 loadData方法，调用第二次的时候就会报如下错误。
java.util.concurrent.RejectedExecutionException: Task com.bmwgroup.connected.social.provider.AbsBaseProvider$OTGInteractive@459cb858 rejected from java.util.concurrent.ThreadPoolExecutor@45d0cac0[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 1]

at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2011)
at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:793)
at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1339)

我使用的是LinkedBlockingQueue 为什么还会抱这样的错误呢该如何使用呢？？
