Hibernate Many to One Mapping using Annotation

In many to one mapping, various attributes can be referred to one attribute only.

In this example, every employee has one company address only and one address belongs to many employees. Here, we are going to perform many to one mapping using annotation.

Let's look at the persistent classes

1) Persistent classes for one to one mapping

There are two persistent classes Employee.java and Address.java. Employee class contains Address class reference and vice versa.

Employee.java

Address.java

2) Add project information and configuration in pom.xml file.

Open pom.xml file and click source. Now, add the below dependencies between <dependencies>....</dependencies> tag. These dependencies are used to add the jar files in Maven project.

3) Configuration file

This file contains information about the database and mapping file.

hibernate.cfg.xml

4) User classes to store and fetch the data

Store.java
