谢谢各位，最后还是采用主动查询的方法，等待10s没结果，主动查询

@PostMapping(value = "/notifyResult", produces = {"application/xml;charset=UTF-8"}) @ResponseBody public String notifyResult(HttpServletRequest request) throws Exception { return "<xml>\n" + " <return_code><![CDATA[SUCCESS]]></return_code>\n" + " <return_msg><![CDATA[OK]]></return_msg>\n" + "</xml>"; } 解决问题
