Spring MVC - validation for comparing two fields

Question

I'm working on a Spring MVC application and have a question about spring validation. First, I have this action in my controller:

@RequestMapping(value = "/create", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody
Employee employeeCreate(@Valid @RequestBody EmployeeModelCreate objModel) throws Exception {
  ...
}

And this is my EmployeeModelCreate class:

public class EmployeeModelCreate implements Serializable {
    ...
    @NotBlank(message = "...")
    private String password;

    @NotBlank(message = "...")
    private String confirmPassword;
    ...

    //Setters and Getters
}

Now, I want to have validation for comparing password and confirmPassword. This validation should be check equality of these two fields. How can I do that? Any help would be greatly appreciated.

You could make a custom validation class, for this you need to implement the Validator interface, then you can use it manually, or bind it to the Spring MVC controller, using the @InitBinder annotation.
