Getter method metadata to support load()/getReference() proxies on field based id --------------------------------------------------------------------------------- Key: HHH-3155 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3155 Project: Hibernate3 Issue Type: Improvement Reporter: Bob Tiernay Currently, the best reason to go with Property mapping in Hibernate performance: If you often loop through collections and only read the id of the entities Hibernate doesn't need to fetch the entities from the database if you use property access type. This is because Hibernate knows getId() only returns the id it already has, but Hibernate has no clue what your getId() method returns if you have marked @Id Long id; Well, what I propose is giving Hibernate a clue, thus opening up the possibility that field based @Id can produce proxies. Perhaps all that is needed is something like this: @Id Long id; @Immutable Long getId(){return this.id}; This way we can convey to Hibernate that getId() has no side effects. -- 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
