Java Digits Validation [closed]

Question

I'm using validation in a int attribute:

@Digits(integer=6,fraction=0)
private Integer idOrder;

But I wanted this attribute has exactly 6 digits.

How can I do that? (Using JSP+Spring+Hibernate)

Answer 1

As you need the 6 digits, I think you should use a String to the property. If in some situations you need it as int, you make a

 public int getIdOrder(){ return Integer.parseInt(idOrder);}

On the String you can use pattern validation. It would be somethind like this:

@Pattern(regexp="\\d{6}")
private String idOrder;

Another option, is keep the idOrder a int and make a getter for the string:

public String getIdOrgetAsString(){
    String s = "000000" + idOrder;
    return s.substring(s.length() - 6);
}

Anyway, there are some options.
