Question

在我的春季项目中，我收到通知后会收到通知服务的通知，如何在浏览器中显示通知数据。这是我的代码。

@RequestMapping(value = "/notify/userregister", method = RequestMethod.POST)
    public ResponseEntity<String> registerNotification(@RequestBody @Valid RegistrationInfo registrationInfo) throws IOException {

        if(registrationInfo != null && registrationInfo.getregistrationInfo()!= null && registrationInfo.getregistrationInfo.size() > 0 ){
                for(int i=0;i<registrationInfo.getregistrationInfo.size();i++ ){
                    logger.info("registration notification data:"+registrationInfo.getregistrationInfo().get(i).getUserAccessId()+registrationInfo.getregistrationInfo().get(i).getRegistrationTime));
                }       

                return new ResponseEntity<String>(HttpStatus.OK);
        }
        else{
            return new ResponseEntity<String>(HttpStatus.NO_CONTENT);
        }
    }

当我的服务器运行时，注册服务发送通知数据。我能够在日志文件中查看数据，并使用200个代码确认注册服务。我想在浏览器中显示通知数据（例如：registrationInfo.getregistrationInfo（）。get（i）.getUserAccessId（））。目前显示“Whitelabel错误页面此应用程序没有显示/错误的显式映射，因此您将此视为回退。这是一个意外错误....”。如何在我的浏览器上摆脱此错误消息？
