Usage of Regular Expression for validation. Back to Validation
Samples:
class ValidateWithRegularExpression implements Serializable {
BigDecimal amount
String usPhone
String usZipCode
String number
String integer
String time
String ipAddress
String ssn
static constraints = {
//validation amount: 999.99 or $999.99
amount(nullable:false, matches:/((\$\d*\.\d{2})|(\d*\.\d{2}))$/)
//validation US phone patterns (999) 999-9999 or (999)999-9999
usPhone(blank:false, matches:/^\([1-9]\d{2}\)\s?\d{3}\-\d{4}$/)
//validation of numbers (numeric characters)
number(blank:false, matches:/(^-?\d\d*\.\d*$)|(^-?\d\d*$)|(^-?\.\d\d*$)/)
//validation of integer numbers
integer(blank:false, matches:/(^-?\d\d*$)/)
//validation of US zip code 99999 or 99999-9999
usZipCode(blank:false, matches:/(^\d{5}$)|(^\d{5}-\d{4}$)/)
//validation of time as a string HH:MM or HH:MM:SS or HH:MM:SS.mmm
time(blank:false, matches:/^([1-9]|1[0-2]):[0-5]\d(:[0-5]\d(\.\d{1,3})?)?$/)
//validation of IP Address(no check for alid values (0-255)) 999.999.999.999
ipAddress(blank:false, matches:/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/)
//validation of Social Security Number 999-99-9999 or999999999
ssn(blank:false, matches:/^\d{3}\-?\d{2}\-?\d{4}$/)
}
