找不到自定义 Java Bean 验证器约束的验证器

Question

我使用此处的说明创建了一个新的自定义验证器： https://docs.jboss.org/hibernate/validator/4.1/reference/en-US/html/validator-customconstraints.html#validator-customconstraints-validator

public class CustomizableTypeValidator implements ConstraintValidator<CustomValidate, CustomValidator> {
    @Override
    public void initialize(final CustomValidate customValidate) {
    }

    @Override
    public boolean isValid(final CustomValidator customValidator, final ConstraintValidatorContext constraintValidatorContext) {
        if ( customValidator == null ) {
            return true;
        }

        return customValidator.isValid(constraintValidatorContext);
    }
}

但得到：

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'com.amazon.mft.data.api.v1.CustomValidate' validating type 'com.amazon.mft.data.api.v1.CustomValidator'. Check configuration for 'transactionEntries[0].record.attributesObj'

我正在使用以下方法创建验证器：

        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        validator = factory.getValidator();

并调用它：

 validator.validate(obj)

我需要做什么才能将自定义验证器添加到它正在执行的其他验证中。我正在使用 Hibernate Validator 5.2.4。

回答我自己的问题：添加 AutoService 注释修复它：

import com.google.auto.service.AutoService;

@AutoService(ConstraintValidator.class)
public class CustomizableTypeValidator implements ConstraintValidator<CustomValidate, CustomValidator> {
    @Override
    public void initialize(final CustomValidate customValidate) {
    }

    @Override
    public boolean isValid(final CustomValidator customValidator, final ConstraintValidatorContext constraintValidatorContext) {
        if ( customValidator == null ) {
            return true;
        }

        return customValidator.isValid(constraintValidatorContext);
    }
}
