Using Cassandra with the Java Spring Framework

Spring is a powerful ecosystem for building applications in Java and other JVM-based languages, providing a flexible, modular architecture that allows you to bring in exactly the capabilities you need. We’ve seen many teams have success delivering Spring-based microservices using Cassandra. Check out these best practices and learning exercises.

Get Started

Using Spring Boot With Cassandra

Spring Boot is the glue that holds a Spring application or microservice together, providing dependency management and wiring together the various Spring modules that you’ve selected. For example, you can build a service that exposes a RESTful API via HTTP using Spring Web, and implement the operations on the API using the DataStax Java Driver. It’s simple to configure the driver using environment variables or configuration files to connect to your Cassandra cluster, whether it’s open source, DataStax Enterprise, or DataStax Astra.

Accessing Cassandra Through Spring Data

Spring Data abstracts the details of interacting directly with database drivers, allowing you instead to interact with Data Access Objects (DAOs) which you annotate with desired persistence options. For simple Cassandra database access, use Spring Data Cassandra. If you want a reactive app, Spring Data Cassandra Reactive is also available.

Starting Your Spring Project

When you’re ready to start building your Spring application, the Spring Initializr is a great tool that allows you to pick which Spring modules you want to use and automatically generates your project configuration and skeleton code.
