Java Persistence with Hibernate Part 4 – Create the Mapping File and Configuration File

We need to tell Hibernate how our persistent class(Student.java) maps to our table(student_table) for Hibernate to be able to load and persist(save) data.

Create the Mapping File

The basic structure of a mapping file is like this:

< ?xml version="1.0" encoding="UTF-8"?>
< !DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate -mapping package="com.phoenixone.hibernate.model">
	<class name="com.tutorial.enrollment.model.Student" table="student">
		<id name="id" column="student_id">
			<generator class="org.hibernate.id.enhanced.SequenceStyleGenerator" />
		</id>
		<property name="firstName" column="first_name" />
		<property name="lastName" column="last_name" />
	</class>
</hibernate>
