@DoubleRangeFieldValidator and @IntRangeFieldValidator in Struts 2

By Arvind Rai, June 15, 2014
@DoubleRangeFieldValidator and @IntRangeFieldValidator are the strust 2 annotation to validate form field. Both validates the form field value for a given min and max. @DoubleRangeFieldValidator checks for double data type and @IntRangeFieldValidator checks for integer value.

@DoubleRangeFieldValidator Annotation in Struts 2

@DoubleRangeFieldValidator checks for double data type value entered by the user. User can entered data in a specified range as min and max. If we do not set min and max, nothing will be validated. Use @DoubleRangeFieldValidator at method level.

message : This attribute is required. This displays the error message.
key : This is I18 key which is obtained from property file.
type : The value of type can be like ValidatorType.FIELD enum.
minInclusive : Minimum double data type value .
maxInclusive : Maximum double data type value .

Syntax
@DoubleRangeFieldValidator(message = "message", key = "i18n.key", shortCircuit = true, minInclusive = "0.54", maxInclusive = "66.98") 
How to use in the code.
public class UserAction extends ActionSupport{
	private double price;
	public String execute() {
	   return SUCCESS; 
	}
	@DoubleRangeFieldValidator(message = "Enter valid price", minInclusive = "0.54", maxInclusive = "66.98")
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
}
