Question

我有几个Spring @ExceptionHandlers如下：

@ExceptionHandler(MailerException.class)
@ResponseStatus(value = HttpStatus.INTERNAL_SERVER_ERROR)
public String mailerException(MailerException e, HttpServletRequest request, Locale locale) {
    FlashMap outputFlashMap = RequestContextUtils.getOutputFlashMap(request);
    if (outputFlashMap != null) {
        outputFlashMap.put("flashMessage", messageSource.getMessage("controller.internal_server_error", null, locale));
    }
    return "redirect:/index";
}

@ExceptionHandler(ExecutionException.class)
public String executionException(ExecutionException e) throws Throwable {
    throw e.getCause();
}

如果引发ExecutionException MailerException作为原因，则会调用executionException处理程序，但不会调用mailerException处理程序...

我不知道为什么......有人可以解释一下吗？

以下是 stacktrace ：

以下是浏览器中显示的内容：

Etat HTTP 500 - Request processing failed; nested exception is java.util.concurrent.ExecutionException: com.bignibou.MailerException: MessagingException | MailSendException

为什么Spring不链接ExceptionHandlers？
