使用spring boot security的時候，配置了一個error頁面，但是請求該頁面的時候 總是返回500錯誤碼

經過除錯，最後是在BasicErrorController，

@Controller
@RequestMapping("${server.error.path:${error.path:/error}}")
public class BasicErrorController extends AbstractErrorController {

@RequestMapping(produces = "text/html")
public ModelAndView errorHtml
 
(HttpServletRequest request,
HttpServletResponse response) {
   HttpStatus status = getStatus(request);
Map<String, Object> model = Collections.unmodifiableMap(getErrorAttributes(
         request, isIncludeStackTrace(request, MediaType.TEXT_HTML)));
response.setStatus(status.value());
ModelAndView modelAndView = resolveErrorView(request, 
 
response, status, model);
   return (modelAndView == null ? new ModelAndView("error", model) : modelAndView);
}
