Validator的使用

1.单独使用Hibernate-validator和Apache BVal

1)Apache BVal

@NotNull
private Integer num;
public Validator getValidatorFactory() {
                ValidatorFactory avf = Validation.byProvider(HibernateValidator.class).configure().buildValidatorFactory();
                return avf.getValidator();
            }
Set<ConstraintViolation<T>> errorSet = getValidatorFactory().validateValue(t, "num",num , true));
         

 

2)Hibernate-validator

@NotNull
private Integer num;
public Validator getValidatorFactory() {
                ValidatorFactory avf = Validation.byProvider(ApacheValidationProvider.class).configure().buildValidatorFactory();
                return avf.getValidator();
            }
Set<ConstraintViolation<T>> errorSet = getValidatorFactory().validateValue(t, "num",num , true));

ConstraintViolation里面是@NotNull的验证不通过信息，当然验证注解不止这么一个，都可以这样验证
2.spring boot自带Hibernate-validator，要想使用Apache BVal

<!-- 数据验证 Validator bean -->
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="providerClass" value="org.apache.bval.jsr.ApacheValidationProvider" />
</bean>
