there is no steps for designing a system in spring boot any feature is not accessible and all are separate and we need config none necessary java classes and many why you are not thinking out of programing language a good work is jhipster that tries a way to facilitate software implementation anyone knows all systems has security anyone know systems can be big data and stream processing why we have hierarchy for creating applications
i a word this designing is rebuilding code redundant and loose our times

Thanks for the suggestion but a graphical interface is out of the scope of the Spring Boot project. If you like JHipster then that's a good option for you.
