关于系统自动判断请求环境的解决方案

//在service中获取request对象
HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
//通过 request 获取 UA 信息

String userAgent = request.getHeader("User-Agent");
//通过 UA 信息中的是否包含某类型的产品信息判断请求来源

if(userAgent.contains("MicroMessenger")){

channel = CHANNEL.WECHAT.getCode();

}else if(userAgent.contains("AlipayClient")){

channel = CHANNEL.ALIPAY.getCode();

}else if(userAgent.contains("")){ //此判断信息待定

channel = CHANNEL.APP.getCode();

}else{

channel = CHANNEL.WEB.getCode();

}
