Custom exception handler for NoHandlerFoundException is not working without @EnableWebMvc

Question

I want to override html error page for 404 responses as an JSON response. When i use @ControllerAdvice without @EnableWebMvc it is not working.

@EnableWebMvc   // if i remove this, it is not working
@ControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class GlobalControllerExceptionHandler {

    @ExceptionHandler(NoHandlerFoundException.class)
    public ResponseEntity<ZeusErrorDTO> noHandlerFoundException(
                    HttpServletRequest request, 
                    NoHandlerFoundException exception) {

        ErrorDTO errorDTO = new ErrorDTO();
        return new ResponseEntity<>(errorDTO, HttpStatus.NOT_FOUND);
    }
} 

Is there an option for custom exception handling without @EnableWebMvc, because it overrides Spring configurations which are declared inside application.yml.

Answer 1

Normally @utkusonmez answer works fine but not in my case, as I am using swagger. So all I did is add following properties in my application.properties file

spring.mvc.throw-exception-if-no-handler-found=true
spring.mvc.static-path-pattern=/swagger*

Now both NoHandlerFoundException and swagger-ui works fine.

Answer 2

I easily resolved problem by adding one of configurations in application.yml.

spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

or

spring.mvc.throw-exception-if-no-handler-found=true
spring.mvc.static-path-pattern: /static

If you don't restrict Spring and no handler matches with your request, then spring tries to look for static content.
