java使用Spring引导验证通用Rest Api

Question

通过引用这个reference，我已经为基本CRUD操作实现了通用RESTAPI服务

这非常有效，但现在我还希望在进一步处理之前验证我的请求

下面是我的通用Rest控制器定义

public abstract class GenericRestResource<DTO extends BaseDTO> {

    protected final ICrudService<DTO> facade;

    protected GenericRestResource(ICrudService<DTO> facade) {
        this.facade = facade;
    }

    @GetMapping
    public List<DTO> list() {
        return facade.findAll();
    }

    @GetMapping(value = "/{id}")
    public DTO get(@PathVariable(value = "id") Long id) throws NotFoundException {
        return facade.find(id).orElseThrow(() -> new NotFoundException(String.format("could not get item with id: %s", id)));
    }

    @PostMapping
    public Long create(@RequestBody @Valid DTO dto) {
        return facade.create(dto);
    }

    @PutMapping(value = "/{id}")
    public void update(@PathVariable("id") Long id, @RequestBody DTO dto) {
        facade.edit(id, dto);
    }

    @DeleteMapping(value = "/{id}")
    public void delete(@PathVariable(value = "id") Long id) {
        facade.delete(id);
    }

}

食物资源。爪哇

@RestController
@RequestMapping(path = "/api/v1/foo")
@Validated
public class FooResource extends GenericRestResource<FooDTO> {

    @Autowired
    protected FooResource (ICrudService<FooDTO> facade) {
        super(facade);
    }
}

BaseDTO。爪哇

@NoArgsConstructor
@AllArgsConstructor
@Data
public abstract class BaseDTO {
    protected Long id;
}

食物。爪哇

@NoArgsConstructor
@Data
@EqualsAndHashCode(callSuper = true)
public class FooDTO extends BaseDTO {
    @NotNull(message = "id is mandatory", groups = {OnUpdate.class, Delete.class})
    @JsonProperty("categoryId")
    private Long categoryID;
    @NotBlank(message = "identifier is mandatory", groups = {OnCreate.class, OnUpdate.class})
    private String identifier;
    @NotBlank(message = "identifier is mandatory", groups = {OnCreate.class, OnUpdate.class})
    private String placeholder;
}

但是，这不会验证对FooDTO的请求，FooDTO是BaseDTO的一种类型。验证仅适用于BaseDTO如果我在id上添加任何验证查询，如@NotNull，我还希望验证FooDTO。 当前的执行有什么问题？请帮助我理解这一点，我如何才能让它工作
