MongoDB Spring Boot Properties

Leave a comment

MongoDB is a provider of Spring Boot for handling NoSQL database operations. To use MongoDB  in your Spring boot application you have to add this MongoDB starter in your pom.xml .

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

After adding MongoDB starter in your application it will automatically download and add the required dependencies in your application and initialize with default values. You can overwrite these values through application.properties / application.yaml .
