How can I validate the string length using java spring validation?

Question

I have this field declared in a model class:

@Size(min = 2, max = 200, message = "{validation.name.size}")
private String name;

where validation.name.size is the path to a localized message. The problem is that I do not want to output a message like 'The name is too long or too short.'.

Is there any way to use two different messages and check minimum and maximum string length? @Min and @Max are only working for numeric types, so they can not be used. What is the alternative for strings?

I think this isn't really user friendly. I'd prefer two separat validations. — F_Schmidt

Maybe not the most realistic example but as a User I may enter a String size 1. I get, "string to short", now I write "thisisaverylongstring......". And now I get "string to long". Isn't this more annoying than the message provided by @chrylis-cautiouslyoptimistic- ? — ChristophE

You can just use the "@Size"-annotation twice:

@Size(min = 2, message = "{validation.name.size.too_short}")
@Size(max = 200, message = "{validation.name.size.too_long}")
private String name;

Yes there is - you can use the @Size.List() and @Size annotations in conjunction like so:

@Size.List({
     @Size(min = 2, message = "{validation.name.size.too_short}"),
     @Size(max = 10, message = "{validation.name.size.too_long}")
})

another option could be to use a regex. something like

^[a-zA-Z0-9]]{2,200}$

it depends if you want to control the characters.
