5.6退出循环的代码在git更新了，就是在catch时，增加一个Thread.currentThread().interrupt();

代码如下:

public class RightWayStopThreadInProd implements Runnable {

    @Override
    public void run() {
        while (true && !Thread.currentThread().isInterrupted()) {
            System.out.println("go");
            try {
                throwInMethod();
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                //保存日志、停止程序
                System.out.println("保存日志");
                e.printStackTrace();
            }
        }
    }

    private void throwInMethod() throws InterruptedException {
            Thread.sleep(2000);
    }

    public static void main(String[] args) throws InterruptedException {
        Thread thread = new Thread(new RightWayStopThreadInProd());
        thread.start();
        Thread.sleep(1000);
        thread.interrupt();
    }
}

  public class RightWayStopThreadInProd implements Runnable {
   
      @Override
      public void run() {
          while (true) {
              System.out.println("go");
              try {
                  throwInMethod();
              } catch (InterruptedException e) {
                  Thread.currentThread().interrupt();
                  //保存日志、停止程序
                  System.out.println("保存日志");
                  e.printStackTrace();
                  return;
              }
          }
      }
   
      private void throwInMethod() throws InterruptedException {
              Thread.sleep(2000);
      }
   
      public static void main(String[] args) throws InterruptedException {
          Thread thread = new Thread(new RightWayStopThreadInProd());
          thread.start();
          Thread.sleep(1000);
          thread.interrupt();
      }
  }
  1. 请问老师不重新设置interrupt标志位，直接return或者break结束也可以吧？
