In this tutorial, we built a simple web application using Java, Spring Boot, the Aerospike Database, and Docker. The steps involved setting up an Aerospike Database Docker container, creating a simple web Java Spring Boot server, and testing the E2E flow by simulating RESTful API requests to create, read, and delete records from the Aerospike Database using Postman. The source code for this demo can be found at aerospike-examples/simple-springboot-aerospikedemo.
