Spring Boot + MongoDB Integration

Spring Boot is a Java-based framework used to build web applications and microservices. It is built on top of the Spring Framework and makes it easy to create stand-alone, production-grade Spring-based applications.

MongoDB is a popular, open-source, NoSQL document-oriented database. It stores data in the form of documents, which are similar to JSON objects. MongoDB is known for its scalability, performance, and ease of use.

Spring Boot can be configured to use MongoDB as its database. This can be done by including the MongoDB driver and Spring Data MongoDB dependencies in the application’s classpath and then configuring the application’s properties to connect to the MongoDB instance. Spring Boot also provides a set of annotations and classes that can be used to interact with the MongoDB database, such as @Document and MongoRepository.

You can use Spring Data MongoDB to access your MongoDB instance. Spring Data MongoDB provides an abstraction layer to access and interacts with MongoDB, it makes it easy to implement MongoDB-based repositories.

To use MongoDB with Spring Boot you need to add the Spring Data MongoDB starter and the MongoDB Java driver to your classpath. The following example shows how to do this using Maven:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

And also add the following configuration to your application.properties/application.yml

spring.data.mongodb.uri=mongodb://username:password@host:port/database

You can also use Spring Data MongoDB with Spring Boot, Spring Data MongoDB provides a specific Repository abstraction for MongoDB, it allows you to use the basic CRUD methods as well as some specific methods for pagination, text search and more.
