Hibernate Hydrate

The primary goal of the Hibernate Hydrate project is to populate a graph of persistent entities and thus avoid the famous LazyInitializationException.

Features

  • Utility class to populate a lazy-initialized object graph by recursivity
  • Supports JPA with Hibernate as provider
  • Supports third Hibernate 3.x, Hibernate 4.x and Hibernate 5.x

Getting Help

This readme file as well as the wiki are the best places to start learning about Hibernate Hydrate. There are also unit tests available to look at.

The wiki contains links to basic project information such as source code, jenkins build, javadocs, issue tracking, etc.
