![]() ![]() When you design a class to be persisted by Hibernate, it is important to provide JavaBeans compliant code as well as one attribute, which would work as index like id attribute in the Employee class. Let us consider our Employee class with getXXX and setXXX methods to make it JavaBeans compliant class.Ī POJO (Plain Old Java Object) is a Java object that doesn't extend or implement some specialized classes and interfaces respectively required by the EJB framework. They can use compile-time checking to help them. You have to add the following dependency in your pom.xml file. The first step in creating an application is to build the Java POJO class or classes, depending on the application that will be persisted to the database. It helps developers stay in their Java-centric, everything-is-an-object paradigm. Step 1: Create a maven project in your favorite Java IDE (In this article we are using IntelliJ IDEA) Step 2: When you have successfully created a maven project you have to add some dependencies in your pom.xml file. In contrast to other mapping frameworks MapStruct generates bean mappings at compile-time which ensures a high performance, allows for fast developer feedback. Provide an identifier property: It is better to assign an attribute as an id.This attribute behaves as a primary key in a database. We will go through the different steps involved in creating a Java Application using Hibernate technology. A no-arg constructor: It is recommended that you have a default constructor at least package visibility so that hibernate can create the instance of the Persistent class by the newInstance() method. Let us now take an example to understand how we can use Hibernate to provide Java persistence in a standalone application. Hibernate Tools is a toolset for Hibernate implemented as an integrated suite of Eclipse plugins, together with a unified Ant task for integration into the build cycle.
