hibernate: How to Use Hibernate 5 in an Application

The hibernate quickstart demonstrates how to use Hibernate ORM 5 API over JPA, using Hibernate-Core and Hibernate Bean Validation, and EJB.

What is it?

The hibernate quickstart is based upon the kitchensink example, but demonstrates how to use Hibernate Object/Relational Mapping (ORM) 5 over JPA in WildFly Application Server.

This project is setup to allow you to create a compliant Java EE 7 application using JSF, CDI, EJB, JPA , Hibernate-Core and Hibernate Bean Validation. It includes a persistence unit associated with Hibernate session and some sample persistence and transaction code to help you with database access in enterprise Java.

Add the Correct Dependencies

WildFly provides Hibernate 5 and JPA support.

If you use Hibernate 5 packaged within WildFly, you will need to first import the JPA API.

This quickstart demonstrates usage of Hibernate Session and Hibernate Validators.

If you look at the pom.xml file in the root of the hibernate quickstart directory, you will see that the dependencies for the Hibernate modules have been added with the scope as provided.

For example:

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-validator</artifactId>
    <scope>provided</scope>
   <exclusions>
      <exclusion>
         <groupId>org.slf4j</groupId>
         <artifactId>slf4j-api</artifactId>
      </exclusion>
   </exclusions>
</dependency>

Access the Application

The application will be running at the following URL: http://localhost:8080/{artifactId}/.

Server Log: Expected Warnings and Errors

You will see the following warnings in the server log. You can ignore these warnings.

WFLYJCA0091: -ds.xml file deployments are deprecated. Support may be removed in a future version.
