How to javaconfig convert?

Answer 1

Create a class with the following:

@ControllerAdvice
public class ExceptionHandling {

  @ExceptionHandler(value=Exception.class)
  public String showErrorPage(){
    return "error";
  }
}

The @ControllerAdvice must be component-scanned so based on your config it must be somewhere in sg.ani.api.controller. This will catch all exceptions and direct them to the error page. So just create a new error page and you should be fine.
