重复通知

通常，每条实时通知只会递送至每个指定终端节点一次。然而，由于Amazon SNS的分布式本质以及瞬态网络条件，偶尔可能会出现重复消息。请务必对应用进行相应设计，避免重复通知消息造成错误或不一致。

AWS参考文档：

public class SnsServletProcessor implements HttpServletProcessor {
    private final SnsMessageManager messageParser = new SnsMessageManager("us-east-1");

    @Override
    public void process(HttpServletRequest httpRequest, HttpServletResponse httpResponse) throws IOException {
        messageParser.handleMessage(httpRequest.getInputStream(), new DefaultSnsMessageHandler() {
            @Override
            public void handle(SnsNotification snsNotification) {
                  // 用于处理通知消息的业务逻辑                   
            }
        };
    }
}
