Learn to build and maintain effective shared Java libraries for Spring Boot applications in this 45-minute conference talk from Spring I/O 2025. Discover practical solutions for common challenges developers face when creating shared libraries, including determining what functionality belongs in a shared library, keeping libraries small and maintainable, and updating them without breaking dependent projects. Explore the structure and implementation of a real-world shared library that has successfully supported Spring Boot integration across multiple projects for over three years. Examine actual code examples and learn to avoid common pitfalls that can lead to bugs or bottlenecks across projects. Gain actionable insights for building new shared libraries or improving existing shared codebases, with practical solutions you can immediately apply to your own Spring Boot projects.
