Question

I have a command class named Parent as follows:

public class Parent {

    private List<Child> childList;

    // getters and setters

}

And a Child class according to

public class Child {

    @NotBlank
    private String name;

    @NotBlank
    private String email;

    @NotBlank
    private Integer age;

}

In Spring validation module, i have been notice a @Cascade annotation.

Question: Does it work in collection-based property as in childList property ? If so, how can i use it ?

With Hibernate Validator 4.0.0 Beta2, you can.

It based on JSR-303 Bean Validation.

Annotate Your List with @Valid to validate the content of the List

@Valid
private List<Child> childList;

Now validate:

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Set<ConstraintViolation<Parent>> constraintViolations = validator.validate(Parent);
