I have an issue where I have only one database to use but I have multiple servers where I want them to use a different table name for each server. Right now my class is configured as: @Entity @Table(name="loader_queue") class LoaderQueue I want to be able to have dev1 server point to loader_queue_dev1 table, and dev2 server point to loader_queue_dev2 table for instance. Is there a way i can do this with or without using annotations? I want to be able to have one single build and then at runtime use something like a system property to change that table name. For Hibernate 4.x, you can use a

I need to have GUID/UUID's as the id column of my rows. This is to be able to create entries both online and offline, and of course not having these conflict on PK when merging. I know i could mitigate this, but i'd like to keep it simple, and there is legacy apps already using uuid/guids to define relationships). Data also needs to be synced both ways later. Rewriting existing applications is not an option. When i try to use either GUID or UUID with grails i get an error 500. (using a GUID on h2 results in another error - detaling that DB does not support GUIDs, as expected). I get this error

What are the possible solutions for stripping the trailing whitespace when mapping char fields in a legacy database? I see the following options: Calling .trim() at the point of use (controller, view, etc) Override property accessors to return .trim() Using a Hibernate UserType to trim the whitespace I'm leaning toward overriding the property accessor so that the domain properties remain consistent throughout the application. I had a similar problem and I could not alter the legacy data. I ended up overriding the accessor for the sake of transparency to my fellow developers. I would recommend

After learning about Hibernate Custom Validators , it has given me an interest in one topic, could I possibly create one base annotation wherein I could set which Validator to use? @Target({ ElementType.FIELD }) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy = validator().class) public @interface CustomAnnotation { public String message(); Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; Class<? extends ConstraintValidator<? extends CustomAnnotation, Serializable>> validator(); } So that I could use @CustomAnnotation in this manner @CustomAnnotation

I experience the following apparently undocumented issue, and I want to understand if I did something wrong Did anyone encounter the same issue? Is it really not documented anywhere? or did I miss something? The behavior is this Assume the following mapping <class name="org.sample.Foo" table="foo"> ... <many-to-one name="bar" class="org.sample.Bar"/> </class> <class name="org.sample.Bar" table="bar" lazy="false"> ... </class> First, as a background, Hibernate default value for the fetch attribute on a many-to-one relation should be " select ", this is at least what is documented (I'll add the

I am new to hibernate and i am having trouble with specifying the location of the mapping file in hibernate.cfg.xml file. I have created an Event object in org.hibernate.tutorial.chapter1.domain.Event.java package with its corresponding Event.hbm.xml file in the same location. I am trying to specify the location in the hibernate.cfg.xml mapping tag but I am getting an InvalidMappingException (). I have added to the post: the exception, the mapping from the mapping file and the project file structure. any advice would be great. 484 [main] ERROR org.hibernate.util.xml.ErrorLogger - Error parsing
