1. Right-click on the pom.xml file.
2. Select Run Maven | Goals... from the pop-up menu. It will open the dialog. Type spring-boot:run in the Goals field. We have used the released version of Spring Boot in the code. However, if you are using the snapshot release, you can check the Update Snapshots checkbox. To use it in the future...
