Understanding End-of-Life (EOL) for Spring Projects: A Guide for Developers

As developers, staying up-to-date with the software we use is crucial—not just for leveraging the latest features but also for ensuring security and stability. In the Spring ecosystem, understanding the End-of-Life (EOL) timelines of various projects is particularly important. Once a project reaches EOL, it no longer receives updates, including critical security patches, making it a potential risk for your applications.

In this post, we'll break down the EOL timelines for various Spring projects, helping you plan your upgrades and migrations more effectively.


1. Spring Framework

The Spring Framework is the backbone of many enterprise applications, so its lifecycle is of paramount importance.

  • Current Version (6.x): The latest version of Spring Framework is supported until late 2024. This gives you time to adopt the new features and improvements it offers.

  • Previous Versions:

    • 5.x: Support ended in 2024, so if you're still on this version, it’s time to plan your upgrade.

    • 4.x: This version reached EOL in December 2020, meaning it's already unsupported and should be upgraded as soon as possible.

    • 3.x: EOL was way back in December 2016, and if your application is still using this version, it’s well overdue for an upgrade.


2. Spring Boot

Spring Boot simplifies application development, and keeping it up-to-date ensures you benefit from the latest performance and security improvements.

  • Current Version (3.x): Expected to be supported until 2025, giving you a few more years of safe usage.

  • Previous Versions:

    • 2.x: Support ended in November 2023, so start planning your migration to the latest version.

    • 1.x: Reached EOL in August 2019. If you’re still on this version, migrating is a must to ensure your application’s security.


3. Spring Cloud

Spring Cloud plays a key role in building distributed systems and microservices. Its lifecycle often aligns with other Spring projects.

  • Spring Cloud 2022.x (latest release train): Supported until 2024-2025, providing a stable platform for your microservices.

  • Previous Releases:

    • 2021.x: EOL is likely in 2023-2024, so consider upgrading to the latest release.

    • Hoxton (2.x) & Greenwich (2.x): Both have reached EOL (in 2021 and December 2020, respectively). It's time to upgrade if you're still using these versions.


4. Spring Security

Security is a critical aspect of any application, and Spring Security ensures that your applications remain secure against evolving threats.

  • Current Version (6.x): Supported until late 2024, aligned with Spring Framework 6.x.

  • Previous Versions:

    • 5.x: Support ended in 2024.

    • 4.x: Reached EOL in December 2020.


5. Spring Data

Spring Data simplifies working with various data stores. Like other Spring projects, it’s essential to keep your versions current.

  • Various Modules (JPA, MongoDB, Redis, etc.): Typically, these modules align with the Spring Framework versions.

    • 2.x series: Supported until 2024.

    • 1.x series: Reached EOL in December 2020.


6. Spring Integration

If your applications rely on messaging and integration patterns, Spring Integration is key.

  • Current Version (6.x): Supported until 2024-2025, in sync with the Spring Framework.

  • Previous Versions:

    • 5.x: EOL in 2024.

    • 4.x: Reached EOL in December 2020.


7. Spring Batch

For batch processing, Spring Batch provides the necessary tools to handle large volumes of data.

  • Current Version (5.x): Supported until 2025.

  • Previous Versions:

    • 4.x: EOL in 2024.

    • 3.x: Reached EOL in 2020.


8. Spring AMQP

Spring AMQP is crucial for messaging with RabbitMQ, and keeping it up-to-date is important for stable communication between services.

  • Current Version (3.x): Supported until 2024-2025.

  • Previous Versions:

    • 2.x: EOL in 2024.

    • 1.x: Reached EOL in 2020.


9. Spring Web Flow

Spring Web Flow simplifies the management of complex workflows within web applications.

  • Current Version (2.x): Supported until 2024, in alignment with the Spring Framework.

  • Previous Versions:

    • 1.x: Reached EOL alongside Spring Framework 3.x.


10. Spring Session

Managing user sessions effectively is critical for scalable applications, and Spring Session makes it easier.

  • Current Version (3.x): Supported until 2025.

  • Previous Versions:

    • 2.x: EOL in 2024.

    • 1.x: Reached EOL in 2020.


Why EOL Matters

End-of-Life dates aren’t just arbitrary deadlines—they signal the end of official support, including updates that protect your application from vulnerabilities. Running software that has reached EOL increases the risk of security breaches and compatibility issues.


What Should You Do?


  • Check Your Versions: Regularly review the versions of Spring projects you’re using.

  • Plan Upgrades: Start planning migrations well before the EOL date to avoid last-minute scrambles.

  • Leverage Long-Term Support: If you need more time, explore options for long-term support (LTS) versions, if available.


Keeping your Spring projects current is an investment in the stability, security, and performance of your applications. Don’t wait until the last minute—start planning your upgrades today!
