为了让一个ApnsService保持活跃，我创建了一个ThreadPoolExecutor来保持线程发送推送。下面是worker的代码：

public static class PushWorker implements Runnable{
        
        private static final Logger log = Logger.getLogger(PushWorker.class);
        
        private String token;
        private String alert;
        private int badge;
        private String sound;
        private ApnsService service;
        
        public PushWorker(ApnsService srv, String t, String a, int b, String s){
            token = t;
            alert = a;
            badge = b;
            sound = s;
            service = srv;
        }
        @Override
        public void run() {

            
            PayloadBuilder payloadBuilder = APNS.newPayload();
            payloadBuilder.sound(sound);
            payloadBuilder.badge(badge);

            payloadBuilder.alertBody(alert);
            

            String payload = payloadBuilder.build();
                        service.push(token, payload);

        }
    }

字符串
当我创建一个worker并在Threadpool中执行它时：

ThreadPoolExecutor pool = new ThreadPoolExecutor(corePoolSize, maximumPoolSize, keepAliveTime, TimeUnit.SECONDS,queue);

pool.execute(worker);

型
程序终止于：PayloadBuilder payloadBuilder = APNS.newPayload();，没有任何错误或异常。但是，如果按照以下方式，它可以工作：

PushWorker worker = new PushWorker(service, token, alert, badge, null);

worker.run();

型
我不知道为什么线程在Threadpool中终止.有人有同样的问题吗？
