Spring boot: Create a simple Web (MAVEN Web project)

1. Create a new MAVEN Web project;

2, add the corresponding dependency package in the Pom.xml file;

3, a new Hellocontroller request control class;

4, write index.jsp page;

5. Write Startup class App.java

6. Launch the application for code testing
