Spring Boot and MongoDB
In this tutorial we'll use Spring Boot to access data from a MongoDB Atlas cluster. To follow along you'll need to sign in to MongoDB Atlas.
FAQ
How does MongoDB connect to Spring Boot?
MongoDB and Spring Boot interact using the MongoTemplate class and MongoRepository interface.
- MongoTemplate: MongoTemplate implements a set of ready-to-use APIs. A good choice for operations like update, aggregations, and others, MongoTemplate offers finer control over custom queries.
- MongoRepository: MongoRepository is used for basic queries that involve all or many fields of the document. Some examples include data creation, viewing documents, and more.
In either case, configuring Spring Boot with MongoDB only takes a few lines of code.
What is Spring Boot used for?
Spring Boot framework is used to create production-ready web applications with default configurations. Developers need not write extensive code. Spring Boot significantly reduces the development time. It automatically adds commonly used libraries for web applications, such as:
- spring-webmvc
- tomcat
- validation-api
Spring Boot also has embedded servlet container support. We can run Java programs as a standalone application by adding the spring-boot-starter-web dependency in pom.xml.
