Question

说

ExecutorService ex = Executors.newFixedThreadPool(nrofthreads);

安排一些工作,并在工作时等待。

However I have same Threadlocal objects in the worker-threads which need to be closed when the batch is done. Therefore, I would like to be able to call a custom close-method on all worker-threads created by the threadpool.

这样做的最合法方式是什么?

1. 现在是一 m,使用:

for(int i =0 ; i<20; i++){ //make sure to touch all threads with 20 runs..
   ex.execute(new Runnable(){
 public void run(){
   tearDownThreadLocals();
 }
   });
}  
ex.shutdown();

但是,这 t对我来说是很强的。

Thanks GJ

页: 1 Executors.newFixedThreadPool(int, ThreadFactory) to adopt a ThreadFactory , 类似:



ExecutorService ex = Executors.newFixedThreadPool(nrofthreads, 
    new ThreadFactory() {
        public Thread newThread(final Runnable r) {
            return new Thread(new Runnable() {
                public void run() {
                    try {
                        r.run();
                    } finally {
                        tearDownThreadLocals();
                    }
                }
            });
        }
    });


http://www.un.org。 仅知<代码>Executors已有一个方法接受ThreadFactory,因此无需明确制定ThreadPoolExecutor。
