Which ORM is Used with Spring Boot + MongoDB?

When developing applications with Spring Boot and MongoDB, many developers encounter confusion about which Object-Relational Mapping (ORM) tool to use. This post aims to clarify your doubts and provide a detailed understanding of the best option for integrating Spring Boot with MongoDB.

The Confusion: Hibernate vs. Spring Data MongoDB

You may have heard of Hibernate being a popular ORM for relational databases like MySQL, but correctly speaking, MongoDB is a NoSQL database. Thus, using Hibernate directly with MongoDB isn’t a conventional approach and might not yield the best results. A common question arises: If Hibernate isn’t suitable, what do we use?

The Answer: Spring Data MongoDB

The best ORM to use with Spring Boot and MongoDB is Spring Data MongoDB. Here are the reasons why it’s a preferred choice for many developers:

Seamless Integration: Spring Data MongoDB integrates effortlessly with Spring Boot, allowing for smoother development and fewer configuration hassles.

Customizable Repositories: It provides a repository support that helps you to create data access layers without much boilerplate code.

Query Creation: You can derive queries from method names for increased convenience, speeding up your development process.

MongoDB Specific Features: It allows you to leverage MongoDB's unique features and optimizations.

How to Integrate Spring Data MongoDB with Spring Boot

Integrating Spring Data MongoDB into your Spring Boot project can be done quickly by following these simple steps:

Step 1: Update Your Maven Dependencies

To get started, you need to include the Spring Data MongoDB starter dependency in your Maven pom.xml file. Add the following code snippet:

Conclusion

In conclusion, if you're working on a Spring Boot project with MongoDB, the most suitable ORM to use is Spring Data MongoDB. It provides the necessary tools and functionalities tailored for MongoDB, facilitating a clean and efficient development experience. By following the steps outlined above, you can easily set up a Spring Boot application that seamlessly interacts with MongoDB.
