💡 [Feature Request] Migrate from Spring Boot 3 and Jackson 2 to Spring Boot 4 and Jackson 3 #1561
Description
Is your feature request related to a problem? Please describe.
Spring Boot 4 has recently released brining some breaking changes. One of them is Jackson 3 has severe collisions with existing Jackson 2. Moving forward we need to follow the Jackson 3 Migration Guide and Spring Boot 4.0 Migration Guide to keep up with the latest updates.
Describe the solution you'd like
I would expect the TelegramBots to upgrade the Spring Boot 3 and Jackson 2 dependencies to Spring Boot 4 and Jackson 3 respectively. The dependencies introduce breaking changes, so code adjustments are needed too.
Describe alternatives you've considered
Spring Boot 4 temporally supports legacy Jackson 2 modules through Jackson 2 Compatibility, however, it's a matter of time when this feature will be dropped. Therefore, we'd better do this change asap.
Additional context
I plan to see if I can contribute to this change. Just updating import names won't be enough since new versions bring new configurations. Thus, complete regression will be required.
