Question

While using Struts2, I am using several annotations to do my validations inside the Model class, in the set() methods, like:

@RequiredStringValidator(message = 'Name is required') @StringLengthFieldValidator(message = 'Name must be between 5 and 60 characters',                                minLength = '5', maxLength = '60') public void setName(String name) {     this.name = name; } 

But I would like how to put a validation do avoid Strange characters, like !, ?, #, $ and etc…

Is there any existing validator I should use like a @RestrictChars or maybe is there some way to use the @StringRegexValidator. Or should I write a new one. Any hint or documentation how to do such would be great.

Answer 1

I found it finally:

Just adding the already existent @RegexFieldValidator gave me the Validator I needed:

@RegexFieldValidator(message = 'Use only Letters or numbers',                        expression = '^[a-zA-Z0-9]+$')  

Thanks anyway guys!
