Spring rest web服务URL版本控制“。”不工作

Question

我有这个URI PRONTO_URI =“/api/v1.1/”与版本1.1 与映射

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

但上部署应用程序这是堆栈跟踪。

ProntoApiServiceController的

代码： “” 类具有映射/api/v1.1/它使用投掷错误但我与V1这是工作的罚款代替V1.1

@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; 
    } 
}

看来你的问题是，ProntoApiViewController和ProntoApiServiceController具有相同的请求映射和冲突。

我创建了2个控制器来验证这一点：

@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"); 
    } 
} 

，我可以确认你正在与V1.1值在URL

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

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

我猜你r问题与URL名称重复有关
