When I use Spring Boot's global exception handler, I got this:
org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'timestamp' cannot be found on object of type 'java.util.HashMap' - maybe not public?
This is my code, and I have import the Spring Security and Thymeleaf in my project.

@GetMapping("/test")
public String test() throws Exception {
throw new Exception("发生错误");

private static final String DEFAULT_ERROR_VIEW = "/error";
private static final Logger LOGGER = LoggerFactory.getLogger(GlobalExceptionHandler.class);
@ExceptionHandler(value = Exception.class)
public ModelAndView defaultErrorHandler(HttpServletRequest request, Exception e) {
LOGGER.error("系统异常", e);
ModelAndView mav = new ModelAndView();
mav.addObject("exception", e);
mav.addObject("url", request.getRequestURI());
mav.setViewName(DEFAULT_ERROR_VIEW);
return mav;
}
}

Your view name should be "error" but not "/error", the view resolver would find the template named error.html in the template folder, if the view resolver can not find one it will use the default one, in which the timestamp is needed in models.
