public class Test{ private String field; private String field2; //自定义校验规则 @AssertTrue(message="个人基本信息-证件号码格式错误", groups = {Group.PC.class}) public boolean isValid() { return "A".equals(this.field) ? isTrue(this.field2) : true; } } public class ValidateUtil { public static <T> void validate(T t, Class<?>... groups) throws ValidationException { Validator validatorFactory = Validation.buildDefaultValidatorFactory().getValidator(); Set<ConstraintViolation<T>> errors = validatorFactory.validate(t, groups); if (!errors.isEmpty()) { for (ConstraintViolation<T> violation : errors) { throw new ValidationException(violation.getMessage()); } } } } 我在使用 ValidateUtil.validate(test)，如果函数名是 isValid()可以校验，如果不带 is ，valid()就不能校验，求指教

 | 2 adimn 2024-03-07 15:35:56 +08:00 那你就进到 validatorFactory.validate 看看是怎么回事 |

 | 5 sijue 2024-03-07 17:00:43 +08:00 public class AssertTrueValidator implements ConstraintValidator<AssertTrue, Boolean> { @Override public boolean isValid(Boolean bool, ConstraintValidatorContext constraintValidatorContext) { //null values are valid return bool == null || bool; } } public interface ConstraintValidator<A extends Annotation, T> { xxxx } -- 注解中指定的方法名是 isValid |

 | 8 chendy 2024-03-08 08:11:07 +08:00 因为 valid 是一个普通方法，isValid 是 boolean 类型的 getter 方法 校验只校验 getter 方法（印象里好像还有字段 |
