北京阿里云ACE会长response.thenAccept(resp -> {
// 处理返回值
});
// 捕获空指针异常
try {
log.info("AliyunAlertController response :{}", new Gson().toJson(resp));
} catch (NullPointerException e) {
// 处理空指针异常，例如记录日志或抛出自定义异常
e.printStackTrace();
}
CopyCopy- 如果问题仍然存在，您可以考虑将异步处理逻辑改为同步处理，以避免潜在的空指针问题。但这可能会影响到程序的性能，因此请确保这是您需要的解决方案。
