title: Whitelabel Error Page, This application has no explicit mapping for /error, so you are seeing this as a fallback
body: <p><a href="https://i.stack.imgur.com/jpFTo.jpg" rel="nofollow noreferrer">enter image description here</a>This is my Controller, I'm accessing with port localhost:8080 it is returning white label error. What may be the  reason?</p>
  
  <pre><code>@RestController 
  public class EmployeeController {
  
  @GetMapping("/")    
  public String hello() {         
  return "service is up and running";     
  }
  </code></pre>
