Spring Cloud Netflix documentation表示可以通过设置error.path属性来更改SendErrorFilter的默认转发路径（/ error）。当我这样做时，我遇到以下错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'basicErrorController' method
public org.springframework.http.ResponseEntity> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)
to {[/proxyServiceError]}: There is already 'proxyServiceErrorController' bean method
public org.springframework.http.ResponseEntity com.acme.controller.ProxyServiceErrorController.error(javax.servlet.http.HttpServletRequest) mapped.

我将我的错误控制器从BasicErrorController建模。我错过了什么？
答案 0 :(得分：0)
您的ProxyServiceErrorController必须实施org.springframework.boot.autoconfigure.web.ErrorController。在春季启动时，BasicErrorController仅在已经实施ErrorController时才会注册。
更改error.path也会影响BasicErrorController。 BasicErrorController和您的ProxyServiceErrorController正在尝试在同一条路径上注册控制器 - /proxyServiceError。
