Hello.groovy file: -

@RestController
class ThisWillActuallyRun {

    @RequestMapping("/")
    String home() {
        "Hello World!"
    } 

}

This is the output in Command Prompt which shows application failed to start

  • Welcome Mit. Could you please copy the error message and post it, instead of uploading an image of it? Makes it easier to copy. – gmauch Sep 24 '19 at 12:58

Check if you have already some server running on that port (8080).

Or configure an another port in

src/main/resources/application.properties

Add this: 

server.port=8073
