Spring 启动应用程序returns 404 没有进入控制器class

Question

Spring 启动应用程序 returns 调用 API 端点时出现 404 错误，甚至没有进入控制器 class

我已经了解了可以在 Whosebug 上找到的可能的解决方案

我测试过的可能解决方案

在 class 级别添加和删除 @RequestMapping
两者均已测试

GetMapping("/get")

和

RequestMapping("/get")

甚至

GetMapping(value = "/get")

添加了 @ComponentScan 即使我的文件夹结构符合指南。
尝试使用 ResponseEntity<Object> 和 @RequestBody 注释

我已经尝试了几乎所有从各种平台获得的解决方案。 Spring 启动应用程序 API 端点应根据其配置的路径调用相应的方法。但是在我的应用程序中，它会在调用任何端点时抛出“404 Not Found”错误。端点似乎未在 spring 应用程序
中注册

控制器Class

@RestController
    @RequestMapping(BACK_OFFICE_BASE_PATH)
    public class ManagementController {
    
        @Autowired
        ManagementService managementService;
    
        @GetMapping(  SLASH_PATH)
        public List<RateTemp> getUpdateRequests(){
            return managementService.getUpdateRequests();
        }
    
        @PostMapping(  SLASH_PATH)
        public RateTemp addRate(@RequestBody RateTemp body) throws BadRequestException {
            if(body != null){
                return managementService.addRate(body);
            }else throw new BadRequestException(ILLEGAL_REQUEST_FIELDS,"");
        }
    }

Answer 1

我已经找到了我的问题的解决方案，但我什至不了解它。无论如何，当我为每个方法分配一个单独的路径时，它就开始工作了。在我之前的代码中，我为不同的 HTTP 方法（GET、POST、PUT 等）分配了相同的路径值。我以前做过这个，但我从来没有遇到过这个错误。我正在尝试了解此错误的原因。

感谢您的建议
