How to add persistence to Struts2 + Spring application using JPA and Hibernate


In my previous post, How to integrate Spring Framework with a Struts2 application, I created a simple web application that used Struts2 and Spring. In this post, I am going to extend that application to add persistence logic using JPA (Java Persistence Architecture) and Hibernate.

I am assuming that you are already familiar with the technologies used in this post – Struts2, Spring and Hibernate.
My goal is to create a project that can be used to jumpstart a Struts2, Spring and Hibernate based development. This is not a detailed tutorial for these technologies.

My current development environment (at the time of developing this project) looks like this:

  • Maven: 2.2.1
  • Java: 1.6.0_20
  • Mac OS X 10.6.4
  • Struts: 2.1.8
  • Spring: 2.5.6
  • Hibernate: 3.4.0.GA
