So this time the blogger will be with you step by step to uncover the mystery of springboot, let it not mysterious.BodyIf we develop any spring boot project, we

as follows: The contents of the Pom.xml file in the parent project are as follows: The parent module introduces Spring-boot-starter-parent as its parent module, which can be simply used by default with the spring boot configuration. And the version of Spring Cloud is introduced as Dalston.release.The pom.xml of the Submodule Registration-center-web relies on the version of the spring cloud. Other future services also rely on this version of Spring Cloud. The following is the contents of the Po
