Spring Boot JSR303 message code in annotation getting ignored

Question

In my Spring Boot app I have a backing bean where I am using JSR303 validation. In the annotation, I have specified the message code:

@NotBlank(message = \"         


        

Answer 1

According to JSR-303 specification message parameters are expected to be stored in ValidationMessages.properties files. But you can override the place where they are looked for.

So you have 2 options:

1. Move your messages to the ValidationMessages.properties file

2. Or override getValidator() method of your WebMvcConfigurerAdapter's descendant (JavaConfig in your case):

   @Override
   public Validator getValidator() {
       LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
       validator.setValidationMessageSource(messageSource());
       return validator;
   }
