Working with IntelliJ

You can use any of the following IDEs

I’ll use IntelliJ IDEA for this project and the up coming projects as well.

Open the Folder

Click on open option:

Choose the shop folder and click OK:

There might be an message at the right bottom of the IDE showing that IntelliJ is resolving dependencies of the shop project:

After IntelliJ resolved the required dependencies, we’ll see the project content at the top left of the IDE:

Hello Spring Stack

Go to src > main > java > co.dongchen.shop
Double click ShopApplication

Add RestController annotation above the ShopApplication class:

                    
                          1

                          @RestController

Also add a helloSpringStack() method in the ShopApplication class:

                    
                          1

Check Application Healthiness in Browser

                    
                          1

                          http://localhost:8080/actuator/health

The status’s value is UP which means the application is healthy.

View Hello Spring Stack in the Browser

                    
                          1

                          http://localhost:8080/hello-spring-stack

Congratulations! Now we have completed our first program.
