I have problem in getting the @RequestMapping to work, I get the following logs; could you please help me understand the log?

Log while booting:

Application.properties:

server.servlet.context-path=/ruler
server.port=80

RestController:

    @RestController
public class myController {
    private final MedicalService medicalService;

    @Autowired
    public myController(MedicalService medicalService) {
        this.medicalService = medicalService;
    }

    @RequestMapping(value="/test")
    public String testRest()
    {
        return "Yay";
    }
}

No web.xml.

1. show your complete controller class or atleast class declaration and annotations 2. how are you calling this endpoint and what is the url u r using? - pvpkiran
Try addin the @ResponseBody annotation to your testRest method - S.Tushinov
@S.Tushinov That is not beneficial, according to documents; using @RestController is equivalent of using @Controller and @ResponseBody - Ace
Shouldn't you be accessing the url along with the port-number? Something like localhost:8080/ruler/test - Nicholas K

Found the answer to my problem here, it was because of project structure, not the configs.

App package should be like com.app then controller would be com.app.controller.

Also You can use @GetMapping with ResponseEntity for more specific information

    @GetMapping(value = "/test")
    public ResponseEntity<String> testRest(){
        return ResponseEntity.ok("Yay");
    }

Change

@RequestMapping(value="/test")

to

@RequestMapping(value="/test", method = RequestMethod.GET)
