Summary: The hibernate
quickstart demonstrates how to use Hibernate ORM 5 API over JPA, using Hibernate-Core and Hibernate Bean Validation, and EJB.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/
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.
Note: This quickstart uses the H2 database included with WildFly Application Server 11. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment!
Note: This quickstart uses a *-ds.xml
datasource configuration file for convenience and ease of database configuration. These files are deprecated in WildFly and should not be used in a production environment. Instead, you should configure the datasource using the Management CLI or Management Console. Datasource configuration is documented in the Configuration Guide for WildFly Application Server.
The application this project produces is designed to be run on WildFly Application Server 11 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.
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>
For Linux: WILDFLY_HOME/bin/standalone.sh
For Windows: WILDFLY_HOME\bin\standalone.bat
mvn clean install wildfly:deploy
This will deploy target/hibernate.war
to the running instance of the server.
The application will be running at the following URL: http://localhost:8080/hibernate/.
Note: 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.
HHH000431: Unable to determine H2 database version, certain features may not work
mvn wildfly:undeploy
You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.
If you want to debug the source code of any library in the project, run the following command to pull the source into your local repository. The IDE should then detect it.
mvn dependency:sources
You may see the following message when you run the command. It indicates the source is not provided in the third-party antlr
JAR.
