Whitelabel error page appears when you hit a url which result into HTTP error. Whitelabel error page is generated by Spring Boot as a default mechanism when no custom error page is found. Provide your code so that it will be easy to see what error it is and how to rectify it.

As a beginner to SpringBoot this error can be happened to anyone at least once due to some reasons. The Application class (eg: SpringAppApplication.java) should be at the root level and the controller classes can be placed under the same level or maybe in a subdirectory. This application class should be denoted using @SpringBootApplication or extends from SpringBootApplication You may miss the @RestController annotation on top of the controller class. Can be missed the mapping annotation.( @PostMapping(/save) or @GetMapping(/id) etc.) finally check whether you are entering the correct request mapping address(URL) because you may miss a slash or annotation. else double-check the spelling. eg: @RequestMapping(/customer)
