In the use of feign a problems in the process of repeated url

If the Controller's father wrote @ RequestMapping interface method, on the Controller to realize the method of annotation @ Controller
An Ambiguous mapping,

is the key problem: my colleague start with the idea of an error in eclipse started no problem, this is very confusing

The problem code:

 
//this API is feign separation public interface 
@ RequestMapping ("/customer ") 
Public interface FinApi {
* new 
@ RequestMapping ("/add ") 
Result<?> Add (@ RequestBody FinDto FinDto) throws the Exception; } 

//the following is feign server-side code 
@ RestController 
Public class FinController implements FinApi {
@ Override 
@ Transactional 
Public Result<?> Add (@ RequestBody FinConsDto FinConsDto) throws the Exception {
//execution 
return null; 

}} 

Start an error:

 
Java. Lang. An IllegalStateException: Ambiguous mapping. Always map 'com. Customer. Controller. FinController' method 
Public com. GSS. Framework. Model. Result<?> Com. Customer. Controller. FinController. Add (com) dto) FinDto) throws Java lang. Exception 
The to {/customer/add} : There is already a 'finController' bean method 

Solution:

Start up an annotation @ Paichu

 @ Component 
Public class MyWebMvcRegistrations implements WebMvcRegistrations {

@ Override 
Public RequestMappingHandlerMapping getRequestMappingHandlerMapping () {
Return new FeignRequestMappingHandlerMapping (); 
} 

Private static class FeignRequestMappingHandlerMapping extends RequestMappingHandlerMapping {
@ Override 
Protected Boolean isHandler (Class<?> BeanType) {
Return super. IsHandler (beanType) & amp; & ! AnnotatedElementUtils. HasAnnotation (beanType, Paichu. Class); 
} 
} 
} 

In the process of solution of a few posts

In the way that Spring Mvc Controller class @ RequestMapping written in the book of the interface methods, then the Controller interface inheritance and realization method of @ RequestMapping will take effect as

RequestMapping Controller class methods must be written in the book of the Controller in the class?
