【中文标题】无法到达请求映射端点，所以我收到 404 错误

【英文标题】：unable to reach request mapping endpoint so im getting 404 error

【问题描述】：

我创建了一个带有请求映射“/route”的新控制器，但无论我做什么，我都无法到达端点localhost:8080/route。我总是得到 404。

如何在不出现 404 的情况下访问端点路由？

@RestController
public interface RouteController 
@ApiOperation(value = "Add a route details to adapter", nickname = "addroute", notes = "Add route details to the table and Send it to ATLAS", tags = 
        "route", )
@ApiResponses(value = 
        @ApiResponse(code = 200, message = "Successful Insertion into DB and Proceded for Transformation"),
        @ApiResponse(code = 405, message = "Invalid Input") )
@RequestMapping(value = "/route", produces =  "application/json" , consumes = 
        "application/json" , method = RequestMethod.POST)
public ResponseEntity<Void> createData(
        @ApiParam(value = "Route Array", required = true) @Valid @RequestBody RouteArray routeArray) ;

实现类

public class RouteControllerImpl implements RouteController 

@Autowired
private RouteService routeService;


@Override
public ResponseEntity<Void> createData(@ApiParam(value = "Route Details", required = true) @Valid @RequestBody RouteArray routeArray) 

    return new ResponseEntity<Void>(routeService.transformRoute(routeArray));

【问题讨论】：

你能检查你的应用程序上下文路径吗？ （您可以在控制台日志中找到它）

注解不适用于接口。尝试将所有注释移至Impl 类

org.springframework.core.log.LogFormatUtils: POST "/route", parameters= springfox.documentation.spring.web.PropertySourcedRequestMappingHandlerMapping: 查找路径处理程序：/route org.springframework。 web.servlet.handler.AbstractHandlerMapping: 映射到 ResourceHttpRequestHandler [Classpath [META-INF/resources/], Classpath [resources/], Classpath [static/], Classpath [public/], ServletContext [/]] resource.ResourceHttpRequestHandler: Resource未找到 FrameworkServlet：已完成 404 NOT_FOUND

【参考方案1】：

您需要在实施中进行一些更改。您不应将 @RestController 与 OpenAPI api 一起使用，而应使用 @Api 注释。您应该在实现此 API 的类上使用 @RestController。

@Validated
@Api(
    value = "route",
    description = The Controller API"
)
public interface RouteController 
@ApiOperation(value = "Add a route details to adapter", nickname = "addroute", notes = "Add route details to the table and Send it to ATLAS", tags = 
        "route", )
@ApiResponses(value = 
        @ApiResponse(code = 200, message = "Successful Insertion into DB and Proceded for Transformation"),
        @ApiResponse(code = 405, message = "Invalid Input") )
@RequestMapping(value = "/route", produces =  "application/json" , consumes = 
        "application/json" , method = RequestMethod.POST)
public ResponseEntity<Void> createData(
        @ApiParam(value = "Route Array", required = true) @Valid @RequestBody RouteArray routeArray) ;

实施：

@RestController
public class RouteControllerImpl implements RouteController 

@Autowired
private RouteService routeService;


@Override
public ResponseEntity<Void> createData(@Valid RouteArray routeArray) 

    return new ResponseEntity<Void>(routeService.transformRoute(routeArray));
