java - Hibernate doesn't use setter when field is null -

-

i want validate data before saving db (check if field not null, add matches regex in setter). if field null, hibernate doesn't use setter. should in case?

@column(name = "table_name") private string tablename;  public void settablename(string tablename) {     assert.hastext(tablename); // assert.hastext() - method spring util     this.tablename = tablename; }

so want method assert.hastext() throw exception if tablename null.

please, take @ hibernate docs. hibernate annotations can validate lot of cool things like: null fields, field size, etc ...

here's doc:

http://hibernate.org/validator/documentation/getting-started/

it's friendly ;)
