Hello folks,

I’m confused about something. So I’m using Spring Boot 3, when I create a @Configuration annotated class that defines some beans, is it necessary that I @Import it in the @SpringBootApplication annotated class? If I don’t do this the beans aren’t available in the application context, but if I do they are loaded. Examples I find online doesn’t do this it seems

For example, I defined a configuration class that sets up various settings for OpenAPI, if I don’t @Import this class in the main application class my beans don’t get used, but if I do they get used, however examples I saw online doesn’t do this.

It depends on the package where your @Configuration class is defined.

The @SpringBootApplication annotation is a meta-annotation for (among others) @ComponentScan, which means it will search for Spring components in the current package and subpackages. If your config class is in one of these packages, it should be picked up automatically, and if not, you need to manually add it to the Spring configuration (or move it to a different package).

Thanks @Riccardo Lippolis! That makes a lot of sense. I had the assumption that @ComponentScan goes as far back as the root project and all classpaths defined from that scope and my main application class was in a different package. This was it 🙏
