Spring JSR-303约束验证不验证Integer字段

Question

我的模型中没有几个数字字段。 SpringValidatorAdapter没有验证这些约束。

如果我声明如下字段的数据类型

public class Demo{

    @Max(value = "7", message = "{max message}")
    @Min(value = "1", message = "{min message}")
    private Integer amount1;

    @Max(value = "7", message = "{max message}")
    @Min(value = "1", message = "{min message}")
    private Integer amount2;
//getters and setters
}

控制器代码段

@PostMapping(value = { "/url" }, produces = "application/json;charset=utf-8")
@ResponseBody
public String test(@RequestBody Map<String, String> formInputs)  {
    Demo dmo=new Demo();
    String amount1 = formInputs.get("userinput1");
    dmo.setAmount1(Integer.parseInt(amount1));
    String amount2 = formInputs.get("userinput2");
    dmo.setAmount2(Integer.parseInt(amount2));
final Validator javaxValidator = Validation.buildDefaultValidatorFactory().getValidator();
final SpringValidatorAdapter validator = new SpringValidatorAdapter(javaxValidator);
errors = new BeanPropertyBindingResult(dmo, dmo.getClass().getName());
validator.validate(dmo, errors);

以下我尝试引用的内容

difference between @size(max = value ) and @min(value) @max(value)

注意：如果我将其更改为String，则工作正常。
