[hibernate-issues] [Hibernate-JIRA] Created: (EJB-360) Create a property to intercept the Configuration for programmatic modification before the EntityManagerFactory is created

Create a property to intercept the Configuration for programmatic modification before the EntityManagerFactory is created ------------------------------------------------------------------------------------------------------------------------- Key: EJB-360 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-360 Project: Hibernate Entity Manager Issue Type: New Feature Components: EntityManager Affects Versions: 3.3.2.GA Reporter: John Leach Attachments: ConfigurationCustomizer.patch Create a property (hibernate.cfg.customizer) in persistence.xml which allows the user to specify a class which can programmatically modify the constructed Configuration object (built via annotations and XML configuration) before the EntityManagerFactory is created. The aim is to provide a third mechanism for configuration, after annotation and XML configuration has been performed. By specifying a user supplied class name the user can then use Configuration methods to access the mappings and make programmatic modifications, such as converting Cascade.ALL (JPA) to cascade all-delete-orphans (Hibernate). The attached patch provides the code modifications, currently used in Spikes, (http://lab.jugtorino.it/trac/sandbox/wiki/Spikes) to allow programmatic modifications of the Configuration object. The patch file was created from the current trunk (18/05/2008) of hibernate-entitymanager, more specifically, trunk/src/java/org/hibernate/ejb. The user supplied class must have a no argument constructor, and implement the org.hibernate.ejb.ConfigurationCustomizer interface. The mechanism is similar to hibernate.ejb.interceptor in concept, except that it acts on the Configuration object rather than on the entity life cycle. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
