往任务队列扔任务，但是内存没有变化？

[已解决问题] 解决于 2019-04-17 10:05

目前我想通过往任务队列扔任务，观察内存变动，来确定任务的大小。但是目前没效果。

线程池代码：

public class CommonThreadPool {

  public final static int CORE_SIZE = 1;
  public final static int MAX_SIZE = 1;
  public final static long KEEP_ALIVE_TIME = 3L;
  public BlockingQueue blockingQueue = new ArrayBlockingQueue(100000);

  private ExecutorService executorService = new ThreadPoolExecutor(
      CORE_SIZE, MAX_SIZE, KEEP_ALIVE_TIME, TimeUnit.MINUTES, blockingQueue,
      new ThreadFactory() {
        @Override
        public Thread newThread(Runnable r) {
          return new Thread("threadname");
        }
      },
      new DiscardPolicy()
  );

  public ExecutorService getExecutorService() {
    return executorService;
  }

}

使用线程池的代码

public static void main(String[] args) throws InterruptedException {
    ExecutorService executorService = new CommonThreadPool().getExecutorService();
    for (int i = 0; i < 10000; i++) {
      executorService.execute(new Runnable() {
        @Override
        public void run() {
          byte[] bytes = new byte[1024];
          try {
            // 500ms，以便保证线程未处理完任务，新来的任务直接进入任务队列
            Thread.sleep(500);
          } catch (InterruptedException e) {
            e.printStackTrace();
          }
        }
      });
    }
  }
