When should I use Spring or Micronaut?

I'm trying to decide between using Spring and Micronaut for my new project. What should I consider?

Both Spring and Micronaut are great frameworks, but they serve different needs. Spring is mature and feature-rich, while Micronaut is designed for microservices with a focus on low memory consumption.

What are the performance differences between the two?

Micronaut generally has better startup time and lower memory usage due to its compile-time dependency injection. Spring, while heavier, offers extensive features and a larger ecosystem.

Can I use both frameworks together?

Yes, you can integrate them, but it might complicate your architecture. It's usually better to choose one based on your project needs.

What about community support and documentation?

Spring has a larger community and more extensive documentation due to its longer presence in the market. Micronaut is growing rapidly, but its resources are still catching up.
