java - ScheduledExecutorService 不会因未捕获的异常而停止线程

Question

来自这里的文档: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledExecutorService.html#scheduleAtFixedRate(java.lang.Runnable,%20long,%20long,%20java.util.concurrent.TimeUnit)

内容如下:

If any execution of the task encounters an exception, subsequent executions are suppressed.

是否有任何等效的 ScheduledExecutorService.scheduleAtFixedRate 在未捕获的异常后不会关闭？

Answer 1

正如 Andy Turner 提到的，您可以使用“Catch-All”-Wrapper:

public class CatchAllRunnable implements Runnable{
     private final Runnable wrappee;

     public CatchAllRunnable( Runnable r ){ wrappee = r; }

     @Override
     public void run(){
         try{ wrappee.run(); }
         catch( Exception e ){ /* LOG e */ }
     }
}

然后安排:

yourScheduledExecutorService.scheduleAtFixedRate( new CatchAllRunnable(originialRunnable), 1, TimeUnit.Minute);

时间当然根据您的要求调整。
