2.配置

String wxpaykey =  
String wxappid =   
String wxmchid =

3.初始化并调用

Map<String, String> parameters = new HashMap<String, String>();  
            MyConfig config = new MyConfig(wxpaykey,wxmchid,wxappid);  
            WXPay wxpay = new WXPay(config);  
            parameters.put("body", goodstitle);// 商品详情  
            parameters.put("nonce\_str", WXPayUtil.generateNonceStr());  
            parameters.put("out\_trade\_no", orderId);  
            parameters.put("spbill\_create\_ip", mchntip);// 调用微信支付API的机器IP  
            parameters.put("total\_fee", orderamt);// 总额  
            parameters.put("notify\_url", notifyurl);// 回调地址  
            parameters.put("trade\_type", "NATIVE");// 总额  
            String sign = WXPayUtil.generateSignature(parameters, wxpaykey);  
            parameters.put("sign", sign);// 签名  
//            String reuqestXml = WXPayUtil.mapToXml(parameters);  
            Map<String, String> resXml = wxpay.unifiedOrder(parameters);  
            Map<String, Object> returnData = new HashMap<String, Object>();  
            if (resXml.get("return\_code").equals("SUCCESS") && resXml.get("return\_msg").equals("OK")  
                    && resXml.get("result\_code").equals("SUCCESS")) \{

\}else\{
