We're excited to announce a new chapter in our partnership with the Spring community: the Spring Session MongoDB integration will become a dedicated open source project directly maintained by MongoDB under its existing Apache 2.0 license.
This transition builds on years of collaboration between the Spring and MongoDB communities. With the upcoming release of Spring Session 4.0, the Spring team began a broader effort to simplify ownership of individual datastore integrations, inviting partners to take direct ownership of their integrations. Doing so was a natural next step for MongoDB, as integration ownership will enable us to provide the level of investment and long-term support that Spring developers expect from tools they rely on every day.
About Spring Session and MongoDB
Spring Session provides a consistent framework for managing user sessions across distributed, cloud-native environments—a challenge that MongoDB's flexible document model and horizontal scaling capabilities are well-positioned to solve. This combination is especially valuable for applications running in containerized or microservices architectures, where session affinity can't be guaranteed and session data structures may vary across different user contexts.
What this means for Spring developers
With MongoDB leading the development of Spring Session MongoDB, developers will receive direct support from the MongoDB engineering team responsible for the MongoDB Java Driver. Issues and feature requests will be handled by a team with deep expertise in both MongoDB's capabilities and the needs of Java developers, ensuring consistent quality and active engagement with the Spring community.
Over the long term, the integration will stay current with the latest MongoDB Java Driver releases and API improvements, without waiting for the Spring Session core release cycle.
“The Spring community has always been a vital part of MongoDB’s journey,” said Massimiliano Marcon, Director of Product Management, Libraries and Tools at MongoDB. “We are excited to deepen our commitment to the community by leading the development of Spring Session MongoDB, ensuring it remains a reliable, open-source integration for developers.”
“We're excited to see MongoDB take ownership of this integration,” said Rob Winch, Spring Security & Session Project Lead at Broadcom. “Their expertise positions them perfectly to drive this integration forward and deliver the innovation our community expects.”
MongoDB’s continued commitment to the Spring community
Spring developers have been among MongoDB's earliest and most innovative users, building everything from enterprise applications to cutting-edge startups on our platform. We are pleased to renew our commitment to the Spring developer community by becoming the stewards of Spring Session MongoDB.
Meanwhile, our investment in other areas of the Spring community is ongoing. We continue to advance Spring Data MongoDB, and to collaborate closely with the broader Spring community on Spring AI to ensure MongoDB remains a first-class experience for modern Spring applications across data and AI workloads.
With MongoDB now directly maintaining the Spring Session MongoDB integration, developers can expect tighter alignment across the MongoDB Java ecosystem and more responsive development, simplifying the path to building robust, stateful applications at scale.
What’s next
The first MongoDB-maintained release of the Spring Session MongoDB integration is targeted for November 2025 under a new Maven artifact. For users of Spring Session prior to 4.0, spring-session-data-mongodb will still be maintained directly by the Spring Team without interruptions. All applications running Spring Session 4.0 and above will simply need to add the Spring Session MongoDB Maven dependency when the new release becomes available.
Developers can follow progress and contribute directly to the MongoDB GitHub organization or monitor updates in the Spring Session 4.0 Release Notes.
