Vaadin 23 + spring-boot 3.0.2 application not launching - spring-boot

Question

We have a vaadin application on version 23 which was using spring-boot version 2.7.3.
We have some old library high vulnerabilities reported by static scan. so to fix that we tried to use the spring-boot version 3.0.2 with the same application. the application build successfully and also it shows that the application started on port xxxx but the application is not launching and also there are no errors on the console. It just shows the following message:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
Is it possible to use spring-boot 3.0.2 with vaadin 23?
the application should be accessible on localhost.

Answer 1

You cannot use Vaadin 23 with Spring Boot 3.
Spring Boot 3 support comes with Vaadin 24. The most recent version is 24.0.0.alpha9.
