Spring Initializr 0.20 Release Notes

Upgrading from Initializr 0.13

Initializr 0.20 uses Spring Boot 3, and therefore requires Java 17.

ProjectGenerationContext disables proxyBeanMethods by default

Configuration classes annotated with @ProjectGenerationContext do not proxy bean methods by default anymore. If you were relying on 'inter-bean references' via direct method calls, you will need to set the attribute to true explicitly.
