一、该问题的重现步骤是什么？

  1. 用第三方的token在gateway那里解析，并且通过feign调用use模块的服务，启动报错，

  2. 我已经按需求配置开启了feign

    这两个注解不管有没有注释都报一样的错误

二、你期待的结果是什么？实际看到的又是什么？

我看了一下依赖包都是

2.8.0.RELEASE

版本的，求解决方法

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

用的是blade 2.8.0.release版本

    你好，我看了一下你发的那个，我和他的问题不一样，我的是blockExceptionHandler这个类，不是WebMvcConfigurer.class] cannot be opened because it does not exist，他那个方法无法解决我这个问题
