I agree 'Starter is the only one recommended entrance', but this is only suitable for ordinary users, In many Spring Boot open source projects, spring.factories file are placed in xx-Spring-boot-starter. Instead of xxX-spring-boot. This is more user-friendly for secondary development. If I want to develop a custom xxX-RocketMQ-Spring-boot-starter extension component, In other open source projects, I can rely only on XXX-Spring-boot instead of XXX-Spring-boot-starter.
