访问swagger链接时报如下错误

原因是@PostMapping 没有配置路径

   @PostMapping
    public UserInfoResponse queryUserNameById(@RequestBody UserInfoRequest request){
        log.info("查询用户姓名请求参数",request);
        UserInfoResponse response = userService.selectUserNameById(request);
        log.info("查询用户姓名返回参数",request);
        return response;
    }
