Advance MongoDB Aggregations with SpringBoot using Amazon Coretto JDK

Blog Post

The code in this repository is discussed in this blog post in the MongoDB Developer Center.

Supported versions:

• Java 21
• Spring boot 4.2.2
• MongoDB 6.0
• MongoDB Java driver 4.11.0
• Maven 3.9.6

Commands

• Start the server in a console with mvn spring-boot:run.
• You can build the project with : mvn clean package.
• You can run the project with the fat jar and the embedded Tomcat: java -jar target/springboot-mongo-atlas-0.0.1-SNAPSHOT.jar but I would use a real tomcat in production.
