[Feature]: Support for Spring Boot 4.0 / Spring Cloud 2025.1

[klhmeyer]

Feature Description

Solace Spring Cloud should be upgraded to Spring Boot 4.0 / Spring Cloud 2025.1. to support newest Spring Boot features. Also the Spring Boot 3.x OSS support end is not too far away (30.6.2026).

Use Case

I want to use Spring Modulith version 2.0.0 (needs Spring Boot 4.0.0) for implementing Transactional Outbox functionality (supporting JPA and MongoDb) together with Solace Spring Cloud.

Proposed Solution

Please prioritize this since it's a blocker for moving to Spring Boot 4

I am the product manager for integration at Solace. We are moving our integration framework and this project (which the framework heavily uses) to Spring Boot 4.x in the next quarter and will have it fully released by May/June 2026. This is well before the end of support for the Spring Boot 3.x releases. This is a major version upgrade and affects many of our Java-based products and we need to be thorough in our testing.
