                    if (message == null) {

修改为：

try {
                Message message = null;
                if (!polling) {
                    Long number = cloudQueue.getAttributes().getActiveMessages();//改为现在这样解决
//                    message = cloudQueue.popMessage();
                    if (number == 0) {
                        polling = true;
                        continue;
                    }
                } else {
                    if (setPolling()) {
                        log.info("Thread" + workerId + " Polling!");
                    } else {
                        continue;
                    }
                    do {
                        log.info("Thread" + workerId + " KEEP Polling!");
                        try {
                            message = cloudQueue.popMessage(WAIT_SECONDS);

                    clearPolling();
