Validation annotation for indicating that a checkbox is checked

Question

I have a custom object that represents my form like:

public class RegisterForm {

    @NotNull(message = "Account name cannot be empty.")
    @Size(min = 3, max = 50, message = "Account name must be between 3 and 50 characters long.")
    private String accountName;


    private boolean termsConditions;
}

My controller looks like:

public ModelAndView create(@Valid AccountForm accountForm, BindingResult bindingResult, HttpServletRequest request) {

}

So I added the boolean termsConditions that will be for a checkbox on the form.

What is the annotation I should use to ensure this value is true? i.e the checkbox is checked.

Answer 1

That would be javax.validation.constraints.AssertTrue. From JavaDoc:

The annotated element must be true. Supported types are boolean and Boolean
