Spring Boot project to create a multi-module configuration [rpm]

A parent module creation

1. Create a spring boot for the demo project name

2. created above on a good project name demo, right click and select New-> Module, New Module to enter the page name is dubbo-server

3, create another Module, name as dubbo-client

4. Delete useless files and folders, including three modules mvnw, mvnw.cmd .mvn files and folders, src directory, only the parent module dependency management

5. Configure the parent pom.xml
