How to get maxlenght of string property using API

Hi all,

Is there some way how to get length of string type property using Hibernate API?

Code:

I didn't found it in net.sf.hibernate.type.StringType or net.sf.hibernate.metadata.ClassMetadata.

My usecase for it is validation of string inputs in web forms (i use Tapestry).

Thanks for tips,

Rob

look for it via the Configuration instead of the more dense and not so detailed SessionFactory metadata.

this is the code:

Code:

Configuration cfg = blabla.getHibConfiguration();
PersistentClass persistentClass = cfg.getClassMapping(clazz);
Property property = persistentClass.getProperty(propertyName);

Iterator it = property.getColumnIterator();
if (it.hasNext()) {
    Column c = (Column) it.next();
    return c.getLength();
}

Thanks for your help Max.

Bye.

Rob

Hi Rob, it would be cool if you could take 1 hour to write a small entry in the wiki on metadata use :-D

We are using SpringFramework to wrapper Hibernate. So now the question is how to do this within spring?

Don't use spring, as I am pretty certain that they do not expose this "implementation detail".

Just got this from from Spring for those who us it

Code:

 LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&SessionFactory");
  Configuration cfg = lsfb.getConfiguration();
