Are there any big spring-boot open source projects?

I am presently working on a spring boot application and would like to see any real-world examples of how large spring boot applications may be built.

I am particularly interested in reference to large open source projects using "spring-data-rest"

Thanks

I know for example this two:

• Project Sagan: https://github.com/RameshMF/sagan
• Zipkin: https://zipkin.io/
