Overview of Hibernate in Spring Boot

Hibernate is an open-source object-relational mapping (ORM) tool for Java. It is used to persist data from Java objects to a relational database. Spring Boot is an open-source Java-based framework used to create a micro-service. It simplifies the bootstrapping and development of a new Spring application. In this article, we will discuss how to use Hibernate with Spring Boot.

What is Hibernate?

Hibernate is an ORM tool for Java. It is used to persist data from Java objects to a relational database. Hibernate provides a powerful, efficient, and easy-to-use API for manipulating data in a relational database. It also provides a powerful query language (HQL) for retrieving data from the database. Hibernate is the most popular ORM tool for Java.

What is Spring Boot?

Spring Boot is an open-source Java-based framework used to create a micro-service. It simplifies the bootstrapping and development of a new Spring application. Spring Boot provides a powerful set of tools for web development on top of the Java EE platform. It also provides a convenient way to configure and deploy an application in a production environment.

How to Use Hibernate in Spring Boot

Using Hibernate in Spring Boot is easy. All you need to do is add the Hibernate dependency to your project's pom.xml file.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.2.Final</version>
</dependency>

Once the dependency is added, you can create a Hibernate configuration file (hibernate.cfg.xml) and add the necessary configuration parameters.

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydb</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">password</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
    </session-factory>
</hibernate-configuration>

Once the configuration is complete, you can create a Hibernate session factory and use it to create a session.

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();

You can then use the session to perform database operations such as querying, inserting, updating, and deleting data.

Conclusion

In this article, we discussed how to use Hibernate in Spring Boot. We saw how to add the Hibernate dependency to the project's pom.xml file and how to configure the Hibernate configuration file. We also saw how to create a Hibernate session factory and use it to create a session. With Hibernate and Spring Boot, you can easily persist data from Java objects to a relational database.
