Java: How to fix Spring @Autowired annotation not working issues

Spring is a powerful framework, but it requires some skill to use efficiently. When I started working with Spring a while ago (actually Spring Boot to develop microservices) I encountered some challenges related to dependency injection and using the @Autowired annotation. In this blog I'll explain the issues and possible solutions. Do note that since I do not have a long history with Spring, the provided solutions might not be the best ones.
