Spring Boot: autowire beans from library project

July 19, 2023 by Tarik

Just found the solution. Instead of defining base packages to scan from separate library, I’ve just created configuration class inside this library with whole bunch of annotation and imported it to my main MyApplication.class: package runnableProject.application; import com.myProject.customLibrary.configuration.SharedConfigurationReference.class @SpringBootApplication @Import(SharedConfigurationReference.class) public class MyApplication { public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); } } package … Read more

When this behavior is not desirable, you can prevent … Read more
