OpenFeign FeignException$NotFound: [404] during [GET] to [http://xxxx/xxx/xxx]问题解决

开发框架：

Spring Boot+SSM+Maven+Eureka+Zuul+OpenFeign

问题描述：

feign.FeignException$NotFound: [404] during [GET] to [http://XudongBack/user/getUserExtById?username=1] [UserService#getUserExtById(String)]: [{"timestamp":"2020-09-19T04:40:22.806+00:00","status":404,"error":"Not Found","message":"","path":"/user/getUserExtById"}]

问题分析与解决：

1、当前微服务调用XudongBack微服务的/user/getUserExtById接口不存在，因为XudongBack微服务只有/user/gerUserExtById接口。

解决方法：

将XudongBack微服务/user/gerUserExtById接口改成/user/getUserExtById接口。
