Spring Rest Web服务URL版本“。”不起作用

Question

I have this URI PRONTO_URI = "/api/v1.1/" with versioning 1.1 with mapping

@RestController
@RequestMapping(ProntoRestURIConstants.PRONTO_URI)
@Scope("request")
public class ProntoBuildApiController{
...
}

but on deploying the application This is the stack trace.

13:02:56,215 ERROR [org.springframework.web.context.ContextLoader] (MSC service thread 1-1) Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0' defined in ServletContext resource [/WEB-INF/context/web-context.xml]: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Cannot map handler 'prontoApiViewController' to URL path [/api/1.1/]: There is already handler of type [class com.nsn.pronto.api.controller.ProntoApiServiceController] mapped.

Code of ProntoApiServiceController: Class has mapping /api/v1.1/ it is throwing error on using "." but is i replace v1.1 with v1 it is working fine

 @RestController
    @RequestMapping(value = ProntoRestURIConstants.PRONTO_URI)
    @Scope("request")
    public class ProntoApiServiceController extends RestApiBaseController {

@GET
    @RequestMapping(value = ProntoRestURIConstants.FETCH_API_VIEWS_BY_PR , headers = "Accept=application/json;  charset=UTF-8")
    public List<com.nsn.pronto.api.domain.ProblemReport> fetchApiViewByProblemReport(@Context HttpServletRequest request) {

        LOGGER.info( " *** fetchApiViewByProblemReport - ENTRY *******" );
        String path;
        List<com.nsn.pronto.api.domain.ProblemReport> lstProblemReport = null;
        try {
            path = URLDecoder.decode( request.getQueryString() , "UTF-8" );

            lstProblemReport = getApiProblemReportBusinessService().fetchApiPRByQueryString( path );
        } catch(UnsupportedEncodingException e) {
            LOGGER.error( e );
        }

        LOGGER.info( " *** fetchApiViewByProblemReport - EXIT *******" );
        return lstProblemReport;
    }
}

Answer 1

Seems your problem is that ProntoApiViewController and ProntoApiServiceController have the same request mapping and is a conflict.

I created 2 controllers to verify this:

@Controller
@RequestMapping("/v1.1/service")
public class ServiceController {

    @RequestMapping(method=RequestMethod.GET, value="/one")
    public void method(){
        System.out.println("Method one from ServiceController");
    }
}

@Controller
@RequestMapping("/v1.1/api")
public class ApiController {

     @RequestMapping(method=RequestMethod.GET, value="/one")
     public void method(){
        System.out.println("Method one from ApiController");
     }
}

And i can confirm you that is working with the v1.1 value in the URL

http://localhost:9090/v1.1/service/one

http://localhost:9090/v1.1/api/one

I guess your problem is related with the duplication of URL names
