Overview of this book

This book will provide a useful hands-on guide to Hibernate to accomplish the development of a real-time Hibernate application. We will start with the basics of Hibernate, which include setting up Hibernate – the pre-requisites and multiple ways of configuring Hibernate using Java. We will then dive deep into the fundamentals of Hibernate such as SessionFactory, session, criteria, working with objects and criteria. This will help a developer have a better understanding of how Hibernate works and what needs to be done to run a Hibernate application. Moving on, we will learn how to work with annotations, associations and collections. In the final chapters, we will see explore querying, advanced Hibernate concepts and integration with other frameworks.

Integration with Struts

Integration with Struts

Struts is an open source web application framework that is designed to support the development life cycle, which includes building, deploying, and maintaining the application. Struts is based on the MVC (Model View Controller) pattern. It is available under Apache License.

The official site of Struts to download the distribution, support, contribution, and tutorials is https://struts.apache.org/.

Here, we will create a Maven-based Struts web application to understand how to integrate hibernate with Struts. In this recipe, we will continue to use the DAO pattern.

Struts has no plugin available for integration with hibernate, so we will manage all hibernate code manually.

Getting ready

In this section, we will create a code file required for hibernate and Struts with a detailed description.

The project dependencies

Here, we will create a Maven project; so, all project dependencies will be mentioned in pom.xml:

Source file: pom.xml

<project xmlns="http://maven.apache.org...
