Hibernate Validator doesn't work well with hibernate persistence when generating DDL ------------------------------------------------------------------------------------ Key: HV-516 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-516 Project: Hibernate Validator Issue Type: Bug Components: engine Affects Versions: 4.2.0.Final Environment: java6, hibernate 3.6.7 Reporter: David J. M. Karlsen Assignee: Hardy Ferentschik Priority: Critical According to http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html_single/... validation annotations should influence the DDL generation. This is not the case. If I have the following field declaration: {noformat} @Length( max=10 ) private String test; {noformat} it will generate the standard 255: {noformat} test varchar2(255 char), {noformat} It appears to be an *ancient* bug - dating back from 2007: From https://forum.hibernate.org/viewtopic.php?t=975612 I do have {noformat} <property name="javax.persistence.validation.mode" value="callback, ddl" /> {noformat} in my persistence.xml configuration. It's needless to say how irritating it is to define the constraints several times for each attribute. Any chance of getting this fixed (or correct the faulty documentation)? It's not a blocker since it's possible to define the constraints twice - once for hibernate persistence - and once for validation - but it is very very inefficient - and can lead to inconsistencies.
