Validate positive integers

Question

I want to allow only positive integers for number fields including zero. How can I define this validation using JSR 303 ?
I tried

1. @Min(value=0 message = "msg1") - But it allows float values like 1.2.

2. @Digits(fraction = 0, integer = 10, message ="msg2") - It accepts negative values.

3. @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!

Just use the annotation @Min in your bean:

@Min(value = 0L, message = "The value must be positive") private Double value;

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")
