请参阅 Whosebug 上的 this thread 或使用 @ControllerAdvice。

您可以很容易地构建自己的错误控制器：

@ControllerAdvice
public class ExceptionHandlingController {

public static final String DEFAULT_ERROR_VIEW = "generalError";

final String NEW_LINE = System.getProperty("line.separator");
StringBuilder stackTraceString = new StringBuilder("");


@ExceptionHandler(Exception.class)
public ModelAndView handleError(HttpServletRequest req, Exception exception) {
    //System.out.println("Request: " + req.getRequestURL() + " raised " + exception);

    ModelAndView mav = new ModelAndView(DEFAULT_ERROR_VIEW);
    mav.addObject("errorMessage", exception.getMessage());

    for (StackTraceElement element : exception.getStackTrace() ){
        stackTraceString.append( element );
        stackTraceString.append( NEW_LINE );
      }
    mav.addObject("stackTrace", stackTraceString);
    mav.addObject("url", req.getRequestURL());
    return mav;
  }
}
