[JIRA] (HHH-15772) deprecate @Target, @Proxy, @Polymorphism

[JIRA] (HHH-15772) deprecate @Target, @Proxy, @Polymorphism

[JIRA] (HHH-15977) Deprecate @Persister

by Jones (JIRA)

Jones ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-15977 ( https://hibernate.atlassian.net/browse/HHH-15977?atlOrigin=eyJpIjoiZjczZT... ) Re: Deprecate @Persister ( https://hibernate.atlassian.net/browse/HHH-15977?atlOrigin=eyJpIjoiZjczZT... ) About EntityPersister We use a custom entity persister for entities that we annotated with @DynamicUpdate The reason is as follow: * DynamicUpdate will only generate sql statement with the properties that were changed * Our entities have important properties: updateUser, updateDateTime which need to be updated as well We tried to add a hibernate listener to update these 2 properties on every flush, but the update sql was only being generated for the properties that were changed… not the properties changed by the hibernate listener. So, we decided to create a customer persister and override the findDirty method in order to also return the indexes for udpateUser and updateDateTime In summary, with the deprecation of @Persister , we’ll need a way to customize findDirty or that hibernate computes the dirty properties after custom flush listeners. I’m happy to provide more info or discuss this further.

[JIRA] (HHH-15772) deprecate @Target, @Proxy, @Polymorphism

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-15772 ( https://hibernate.atlassian.net/browse/HHH-15772?atlOrigin=eyJpIjoiZWMyNW... ) Re: deprecate @Target, @Proxy, @Polymorphism ( https://hibernate.atlassian.net/browse/HHH-15772?atlOrigin=eyJpIjoiZWMyNW... ) Yeah so that’s a simply terrible thing to do. Instead, use the static methods on the Hibernate class if you need access to the concrete type of a proxy.

[JIRA] (HHH-15772) deprecate @Target, @Proxy, @Polymorphism

by Jones (JIRA)

Jones ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-15772 ( https://hibernate.atlassian.net/browse/HHH-15772?atlOrigin=eyJpIjoiZmRkYT... ) Re: deprecate @Target, @Proxy, @Polymorphism ( https://hibernate.atlassian.net/browse/HHH-15772?atlOrigin=eyJpIjoiZmRkYT... ) About the @Proxy annotation. We’re using extensively in our application (300+ entities has it) For all these cases, I believe 100% of them we’re using as @Proxy(lazy=false) to annotate an entity in an entity hierarchy using single table and column discriminators. Without the annotation, it’s very common that hibernate loads a proxy, instead of the real entity class which very often leads to some ClassCastException in several places. The https://hibernate.atlassian.net/browse/HHH-16254 ( https://hibernate.atlassian.net/browse/HHH-16254 ) is one example that hibernate behaves differently from the hibernate 5.x series. An proxy is returned if I’m using cache, fetch mode select and batch fetch. If I change one of these parameters, like drop the cache, or disable batch fetch, hibernate will not return me a proxy, but the real entity. For our use cases, what’s important is to have a way to configure our mappings that a proxy won’t be returned, but the real class. I’m very interested in discuss this further and provide more info if needed in order to see how this situation is best solved.
