sprin 支援實現ErrorController 來自定義錯誤頁面
下面是具體程式碼的實現

@Controller
public class CustomErrorController implements ErrorController {
    @Autowired
    private ErrorAttributes errorAttributes;
    private final static String ERROR_PATH = "/error";

    @Override
    public String getErrorPath() {
        return ERROR_PATH;
    }
    @RequestMapping(value = ERROR_PATH, produces = "text/html")
    public ModelAndView errorHtml(HttpServletRequest request) {
        Map<String, Object> map = getErrorAttributes(request, false);
        ModelAndView mav =new ModelAndView("error/error", map);
        return mav;
    }
    @RequestMapping(value = ERROR_PATH)
    @ResponseBody
    public ResponseEntity<Map<String, Object>> error(HttpServletRequest request) {
        Map<String, Object> body = getErrorAttributes(request, getTraceParameter(request));
        HttpStatus status = getStatus(request);
        return new ResponseEntity<>(body, status);
    }

    private boolean getTraceParameter(HttpServletRequest request) {
        String parameter = request.getParameter("trace");
        if (parameter == null) {
            return false;
        }
        return !"false".equals(parameter.toLowerCase());
    }

    private HttpStatus getStatus(HttpServletRequest request) {
        Integer statusCode = (Integer) request
                .getAttribute("javax.servlet.error.status_code");
        if (statusCode != null) {
            try {
                return HttpStatus.valueOf(statusCode);
            } catch (Exception ex) {
            }
        }
        return HttpStatus.INTERNAL_SERVER_ERROR;
    }


    private Map<String, Object> getErrorAttributes(HttpServletRequest request,
                                                   boolean includeStackTrace) {
        RequestAttributes requestAttributes = new ServletRequestAttributes(request);
        Map<String, Object> map = this.errorAttributes.getErrorAttributes(requestAttributes, includeStackTrace);
        String URL = request.getRequestURL().toString();
        map.put("URL", URL);
        return map;
    }
}
 

需要說明的是，如果使用了controlleradvice 註解實現了全域性異常控制，那麼自定義錯誤頁面將不會起作用
