我在dto和api类中添加了正确的验证注解，但是当我通过postman输入错误数据时，它不会出错。
api类

@RestController
@RequestMapping("/laptops")
@Validated
public class LaptopApi
{
    @Autowired
    private LaptopService laptopService;

    @Autowired
    private Environment environment;

    @GetMapping("/{id}")
    public ResponseEntity<LaptopDTO> getLaptop(@PathVariable Integer id)
    {
        LaptopDTO laptop = laptopService.getLaptop(id);
        return new ResponseEntity<>(laptop, HttpStatus.OK);
    }

    @GetMapping("/")
    public ResponseEntity<List<LaptopDTO>> getLaptops()
    {
        List<LaptopDTO> laptops = laptopService.getLaptops();
        return new ResponseEntity<>(laptops, HttpStatus.OK);
    }

    @PostMapping("/")
    public ResponseEntity<LaptopDTO> addLaptop(@RequestBody @Valid LaptopDTO laptopDTO)
    {
        Integer laptopId = laptopService.addLaptop(laptopDTO);
        return new ResponseEntity<>(laptopDTO, HttpStatus.OK);
    }

    @PutMapping("/")
    public ResponseEntity<LaptopDTO> updateSpecs(@RequestBody @Valid LaptopDTO laptopDTO)
    {
        laptopService.updateSpecs(laptopDTO);
        return new ResponseEntity<>(laptopDTO, HttpStatus.OK);
    }

    @DeleteMapping("{id}")
    public ResponseEntity<String> deleteLaptop(@PathVariable Integer id)
    {
        laptopService.deleteLaptop(id);
        return new ResponseEntity<>(environment.getProperty("API.LAPTOP_DELETE_SUCCESS")+" "+id,
                HttpStatus.OK);
    }

dto类（我在一个单元测试上运行了regex检查，它工作正常）

public class LaptopDTO
{
    private Integer id;

    @NotNull
    private String name;

    @NotNull
    @Pattern(regexp = "(Intel core i[3579] [0-9]{4,}[A-Za-z]*)" +
                        "|(AMD Ryzen [3579] [0-9]{4,}[A-Za-z]*)",
            message = "microcenter.cpu.invalid")
    private String cpu;

    @NotNull
    @Min(value = 4)
    private Integer ram;

    @NotNull
    private Integer nvme;

    @NotNull
    private Integer ssd;

    @NotNull
    private Integer hdd;

    @NotNull
    @Pattern(regexp = "(Intel U?HD [56][23]0)|" +
                        "([Nn]vidia Geforce [GR]TX [123][06][5678]0)(| super| Ti)",
            message = "microcenter.gpu.invalid")
    private String gpu;

   ... //constructors and methods
  }

json请求正文：

{
    "name": "asegjbofld;bsgj",
    "cpu": "radhtrhsth",
    "ram": 2,
    "nvme": 512,
    "ssd": 1000,
    "hdd": 2000,
    "gpu": "newga"
}

基于来自json请求体的无效cpu和gpu输入，它应该是错误的，因为gpu和cpu，但是请求得到了处理？有什么办法解决吗？谢谢。
