how to return a custom message in jsp using spring 3 mvc and hibernate validator(jsr303)

I have a project using spring 3 mvc and hibernate validator to validate form object.

I follow spring's document

In my controller, I can get bindingresult, which bindingresult.hasErrors() == true.

I use ReloadableResourceBundleMessageSource to do the error message binding.

And my question is: Is it possible that I can have a more flexible error message display in my jsp web page?

For example, I want to say "the app name UserEnteredAppName is not valid. The size should be between 2 and 255".

In my message.property, I define:

Size.appNameForm.itemName=the app name {What Should I do in this brace？} is not valid. The size should be between {1} and {2}

{1} and {2} can be interpolated to '2' and '255'. but how can I get the UserEnteredAppName in the interpolated message?

Below is my form class and controller class:

My controller class:

@RequestMapping(value="foo.htm")
public String handleAppNameFormSubmit(@Valid @ModelAttribute("appNameForm") AppNameForm form, BindingResult result){
}

My form class:

public class AppNameForm implements IForm{
    @NotEmpty
    @Size(min = 1, max = 255)
    private String itemName;
    ....
}

I find some l开发者_开发知识库inks which give me some hint:

for example: How do I dynamically resolve message parameters with Hibernate Validator?

But I am using spring mvc and spring controll which jsr303 implementation to use, I cant find a way to use custom validator, extending hibernate's default ValidatorImpl.

What I am thinking the solution is, I can have custom validator, which will reject the UserEnteredAppName into the bindingResult. is it possible? or I should find another way?

Thanks Andrew

As of release 4.2 Hibernate Validator provides ValueFormatterMessageInterpolator, a new message interpolator which should fulfill your requirements.

With that interpolator you can refer to the validated value using the place holder ${validatedValue}. You can also specify a format string to be applied like this: ${validatedValue:[format string]}, e.g. ${validatedValue:%1$ty} if the validated value is a date.

An example for using this interpolator can be found in the Hibernate Validator reference guide.
