Can I use Calendar in a Struts2 Validator Annotation?

Is it possible to use the java.util.Calendar in a Struts2 IntRangeFieldValidator?

The following code does not produce any OGNL errors but does not work either. I'm trying to create a validation rule for a year range, min= 1970 and max= current calendar year.

@RequiredFieldValidator(message="Year cannot be blank")
@IntRangeFieldValidator(message="Year must be greater than 1970", min="1970", max="ja开发者_运维技巧va.util.Calendar.getInstance().get(java.util.Calendar.YEAR)", fieldName="year")
    public Integer getYear() {
        return year;
    }

Is there a better way to do this without writing a custom validator? Any/All replies are appreciated. Thanks in advance!

I think it should be:

@java.util.Calendar@getInstance().get(@java.util.Calendar@YEAR)

To be confirmed.

Are you able to use the DateRangeFieldValidator?

Here's a list of additional validators:

Try using @FieldExpressionValidator in such a manner:

@FieldExpressionValidator(fieldName = "year", message="Year must be greater than 1970", 
expression = "year < @java.util.Calendar@getInstance().get(@java.util.Calendar@YEAR)") })
