hibernate-validator

If have a Java class with some fields I want to validate using Hibernate Validator. Now I want my users to be able to configure at runtime which validations take place. For example: public class MyPojo { ... @NotEmpty String void getMyField() { ... } ... } Let's say I want to remove the NotEmpty check or replace it with Email or CreditCardNumber , how can I do it? Is it even possible? I guess it comes down to changing annotations at runtime... You can't do it normally. Here's what I've done to get more dynamic validations working via Hibernate Validator. Extend the ClassValidator class.

I've got a bean I'd like to do conditional validation on. For this purpose, I've defined a DefaultGroupSequenceProvider<MyObject> which returns the list of groups to validate against. Now, when validating an object that violates the constraints in more than one group in the sequence, only the first group with failures return it's result. I'd like to get an error on all violations, not just the ones in the first group with failures. I'm thinking that this doesn't need a code-sample, but if I'm wrong, I'll be happy to provide one. I followed this http://kh-yiu.blogspot.com/2014/04/conditional

I have an entity on which I need to implement the following constraint: "There may only ever be one record for any combination of columns X and Y, for which column Z is null if the record is of type A." The last part turns this from a simple uniqueness constraint to something more complex. I'm writing a custom Hibernate validator to check it. What I'm doing is: @Override public boolean isValid(MyEntity value, ConstraintValidatorContext context) { Query query = DB.createQuery( // DB is just a convenience class "select count(*) from MyEntity" + " where propertyX = :propertyX" + " and propertyY =

I am trying to add a unit test for an annotated bean in spring using JSR-303 validation. The bean is a simple one like this: public class Bean { @Size(max=XX) String text; } In the Spring config I have the all the necessary JAR-files: validation-api hibernate-validator The validator is initialized with: <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> My attempt at a testcase looks like this (the spring and other fluff removed): @Autowired private LocalValidatorFactoryBean factory; @Test public void testTemplateFormBeanValidation() { //

I know that exist annotation @Future. If I annotate field with this annotation @Future private Date date; date must be in future means after current moment. Now I need to validate that date was at least 24 hours after current moment. How can I make it? AfterTomorrow.java: @Target({ FIELD, METHOD, PARAMETER }) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy = AfterTomorrowValidator.class) @Documented public @interface AfterTomorrow { String message() default "{AfterTomorrow.message}"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; }

Hi In my spring webapp I have a password variable which I want to be at least 0 characters or more than 6 and less than 20. I know that there is annotation: @Size(min=6, max=20) but I have no idea how to add possibility that password can be 0 characters. Will somebody help me with this? Given the comment, you can use StringTrimmerEditor to convert empty string to null, and then @Size check will not trigger (null is considered as valid in @Size). In your controller add following method: @InitBinder public void initBinder(WebDataBinder binder) { binder.registerCustomEditor(String.class, new
