zhufeizzz commented on issue #1622: 跟SpringMVC共用的时候会存在路径冲突 URL: https://github.com/apache/servicecomb-java-chassis/issues/1622#issuecomment-604192165 @liubao68 你说的这个配置已经添加，问题的原因是SpringMVC会扫描到RestSchema类，并通过此方法判断`org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#isHandler`，因为用到的RequestMapping注解，所以被扫描到。 ``` protected boolean isHandler(Class<?> beanType) { return (AnnotatedElementUtils.hasAnnotation(beanType, Controller.class) || AnnotatedElementUtils.hasAnnotation(beanType, RequestMapping.class)); } ``` 完整错误日志如下： ``` [2020-03-26 10:20:35,366]-[]-[]-[main]-[org.springframework.boot.SpringApplication.reportFailure(SpringApplication.java:826)]-[ERROR] Application run failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping.
