How can I solve the issue of “ this application has no explicit mapping for/ error, so you are seeing this as a fallback” during the development of a project?

 In the context of DevOps, if you are getting the error message or issue of “ this application has no explicit mapping for/ error, so you are seeing this as a fallback”, then here are the steps or points given of how you avoid this particular issue by troubleshooting it:-

Check controlling Mapping

Try to ensure that you have a controller class with a method incorporated with “ @RequestMapping”. For example:-

@Controller

Public class MyController {

    @GetMapping(“/url”)

    Public String handleUrlRequest() {

        // Your logic here

        Return “viewName”;

    }

}

Verification of Configuration

Ensures that your application has the right Configuration system or not such as @ComponentScan or @SpringBootApplication for scanning and recognizing your controller class.

@SpringBootApplication

Public class YourApplication {

    Public static void main(String[] args) {

        SpringApplication.run(YourApplication.class, args);

    }

}

Checking URL in browser

Also ensure that your URL is correct or not. It should be accessible as sometimes the incorrect URL can cause this issue.
