I want to allow only positive integers for number fields including zero. How can I define this validation using JSR 303 ?
I tried
@Min(value=0 message = "msg1") – But it allows float values like 1.2.
@Digits(fraction = 0, integer = 10, message ="msg2") – It accepts negative values.
@Min(value=0, message = "msg1" )
@Digits(fraction = 0, integer = 10, message ="msg2") – It works fine but sometimes both the messages i.e. msg1 and msg2 are displayed.
Any suggestions?
Thanks!
Looks like you are looking for natural numbers, I think you can use the regex pattern to get the desired output. Something like
@Pattern(regexp = "[\\s]*[0-9]*[1-9]+",message="msg")
