Spring Boot ORM Tutorial

What is Spring Boot ORM?

The Spring Boot Framework integrates well with ORM frameworks like Hibernate, Java Persistence API (JPA), Java Data Objects (JDO) and iBATIS SQL Maps. Spring provides resource management, data access object (DAO) implementations, and transaction strategies.

In this tutorial, we'll cover all the important ORM frameworks which are supported by Spring ORM framework which helps in solving the common problems developers/users face in spring Boot framework based applications.

This Spring Boot ORM tutorial is based on the latest Spring Boot 3.5.6 Version.

Why to Learn Spring Boot ORM?

Spring ORM facilitates ORM configurations and easy deployment. Following are the key benefits of using Spring framework to create ORM DAO.

• Easy to Test − Using spring IoC, an ORM implementation can be easily configured. Each piece of persistence unit can be tested in isolation.

• Common Data Access Exception − Spring wraps ORM Tools exceptions to a common runtime exception as DataAccessException. This approach helps to handle most persistence exception (non-recoverable) in appropriate layers. No need to handle ORM specific boilerplate catch/throws/exception declarations.

• General Resource Management − Spring application contexts manages persistence objects, their configurations easily. For example, Hibernate SessionFactory instances, JPA EntityManagerFactory instances, JDBC DataSource instances, iBatis SQL Maps configuration objects and other related objects. Spring handles the local as well JTA transaction management by itself.

• Integrated transaction management − Spring AOP can be used to wrap an ORM code with a declarative AOP styled interceptor either using @Transaction annotation or by specifying transaction AOP advice in XML configuration file. Spring handles transaction semantics, exception handling, rollback and so on. Spring allows to swap transaction managers without affecting the ORM code.

Who Should Learn Spring Boot ORM?

This Spring Boot ORM tutorial is designed for Java developers to understand and develop production−ready spring applications with minimum configurations. It explores major features of Spring Boot such as Starters, Auto−configuration, Beans, Actuator and more. By the end of this tutorial, you will gain an intermediate level of expertise in Spring Boot.

Prerequisites to Learn Spring Boot ORM?

This Spring Boot ORM tutorial is written for readers who have a prior experience of Java, Spring, Maven, or Gradle. You can easily understand the concepts of Spring Boot if you have knowledge on these concepts. It would be an additional advantage if you have an idea about writing a RESTful Web Service interacting with database. If you are a beginner, we suggest you to go through tutorials related to these concepts before you start with Spring Boot.
