对于微信API我早已是无力吐槽，真的是看一次吐一次，这么乱大家造嘛，
关于微信开发和微信API遇到的坑比所有的套路都深，简直是生无可恋，哎
下面给大家提供一个有关于微信企业付款的代码吧，不多说，直接上代码：
private Logger logger = Logger.getLogger(getClass());
// 开发者ID
private String AppID = "";
// 商户号
private String mchId = "";
// 支付key
private static String key = "";
// 统一下提现地址
private String UNIFIED_FEEDBACK_URL = "https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers";
// 校验用户姓名选项
private String check_name = "NO_CHECK";
// 校验用户姓名选项
private String send_name = "";
// 企业付款描述信息
private String desc = "";
@Autowired
private UserService userService;
@RequestMapping("/pay")
@ResponseBody
public boolean pay(HttpServletRequest request,Integer userid) throws Exception {
Userinfo user = UserUtils.getUserById(request, userid);
boolean falg = true;
SortedMap<Object, Object> parameters = new TreeMap<Object, Object>();
StringBuffer param = new StringBuffer();
param.append("mch_appid=" + AppID);
param.append("&mchid=" + mchId);

String currTime = TenpayUtil.getCurrTime();
String strTime = currTime.substring(8, currTime.length());
String strRandom = TenpayUtil.buildRandom(4) + "";
param.append("&partner_trade_no=" + strTime + strRandom);
param.append("&openid=" + user.getOpenid());
param.append("&check_name=" + check_name);
param.append("&re_user_name=" + user.getName());// 收款人姓名
int amount = (int) ( 10 * Math.random() + 100);
//int amount =(int) (Math.random()*100+100);
request.getSession().setAttribute(Constants.REDPACKET, amount);
param.append("&amount=" + amount);
param.append("&desc=" + desc);
InetAddress inetAddress = InetAddress.getLocalHost();

}

导出研究这个企业付款时也是各种坑，还好熬过了这些坑
*注：主要代码段是第一段，后续的那些是在网上都可以找到的工具类
写下这些希望可以帮到那些被坑过套路过的
