Hibernate Validator, custom ResourceBundleLocator and Spring

Question

I\'m trying to override default ResourceBundleLocator in hibernate validation 4.1. So far it works perfectly, but the only examples of its usage include java code to instant

Answer 1

The magic method that does the required job is LocalValidatorFactoryBean#setValidationMessageSource(MessageSource messageSource).

First of all, contract of the method:-

Specify a custom Spring MessageSource for resolving validation messages, instead of relying on JSR-303's default "ValidationMessages.properties" bundle in the classpath. This may refer to a Spring context's shared "messageSource" bean, or to some special MessageSource setup for validation purposes only.

NOTE: This feature requires Hibernate Validator 4.1 or higher on the classpath. You may nevertheless use a different validation provider but Hibernate Validator's ResourceBundleMessageInterpolator class must be accessible during configuration.

Specify either this property or "messageInterpolator", not both. If you would like to build a custom MessageInterpolator, consider deriving from Hibernate Validator's ResourceBundleMessageInterpolator and passing in a Spring MessageSourceResourceBundleLocator when constructing your interpolator.

You can specify your custom message.properties(or .xml) by invoking this method... like this...

my-beans.xml

    
        
    



    
        
            META-INF/validation_errors
        
    

validation_errors.properties

javax.validation.constraints.NotNull.message=MyNotNullMessage

Person.java

    class Person {
    private String firstName;
    private String lastName;

    @NotNull
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
}

BeanValidationTest.java

    public class BeanValidationTest {

    private static ApplicationContext applicationContext; 

    @BeforeClass
    public static void initialize() {
        applicationContext = new ClassPathXmlApplicationContext("classpath:META-INF/spring/webmvc-beans.xml");
        Assert.assertNotNull(applicationContext);
    }

    @Test
    public void test() {
        LocalValidatorFactoryBean factory = applicationContext.getBean("validator", LocalValidatorFactoryBean.class);
        Validator validator = factory.getValidator();
        Person person = new Person();
        person.setLastName("dude");
        Set> violations = validator.validate(person);
        for(ConstraintViolation violation : violations) {
            System.out.println("Custom Message:- " + violation.getMessage());
        }
    }

}

Outupt: Custom Message:- MyNotNullMessage
