Question

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

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

但是在部署应用程序时这是堆栈跟踪。

ProntoApiServiceController代码：类有映射/api/v1.1/使用“。”时抛出错误。但是我用v1替换v1.1它工作正常

 @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;
    }
}

似乎你的问题是 ProntoApiViewController 和 ProntoApiServiceController 具有相同的请求映射并且是冲突。

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");
     }
}

我可以确认您正在使用URL中的v1.1值

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

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

我猜你的问题与网址重复有关

Spring rest Web服务URL版本控制“。”不工作
