Spring无法在java文件中检测WebException

我试图从一个给定id的服务器获取数据，每件事都运行良好，所以我想像处理无效id一样处理代码中的异常，这样服务器上就没有数据了，服务器会抛出一些错误，所以我想处理该异常，所以我尝试使用web异常，但spring没有检测到它

错误是：

无法将WebException解析为类型

我的java文件：

try{
          result = restTemplate.exchange("https://example.com/{id}",  HttpMethod.GET, new HttpEntity<String>(createHeaders()), String.class);

        }

        catch(WebException e) {
            System.out.println(e);

        }

这是春天吗？如果是，exchange方法不会抛出WebExceptoin，而只是一个RestClientException，因此您不能在捕获WebException的尝试捕获中使用它，因为它永远不会发生。是的，是Spring RestTemplate在rest模板中接受WebException我需要使用什么方法？您不需要。RestTemplate中的任何方法都不会引发WebException。您无法捕获永远不会抛出的异常。而是捕获RestClientException。
