I have to admit it. I had the worst time with Hibernate when I first started learning it a few years ago. Although I could see the power, the configuration inside Spring was a bit of a nightmare back then.
Today, both Spring and Hibernate support annotation-based configuration, which makes the whole process easier. Combine this with Hibernate’s Auto-DDL ability (that is, automatic table creation), and it is quite simple to use Hibernate with Spring as long as you follow a few conventions.
The purpose of this article is to build a Hibernate managed Spring web application. Here are the primary goals:
- No SQL scripts, not even table creation scripts
- Minimum XML configuration
- Relationships defined by Java Persistence API (JPA) annotations
- Read, write and edit two related classes
- Make the framework extensible for adding other classes with minimal work
