开发流程概述

开通企业付款到余额功能  
去商户后台获取商户账号appid、商户号、证书  
生成签名  
生成请求XML  
向微信请求付款  
付款结果分析保存  
1、开通企业付款到余额功能  
可以参照官方教程

2、获取商户相关信息  
方法自行百度

3、生成签名和请求XML  
生成签名的官方教程链接  
下面是具体的方法

/\*\*  
     \* 生成请求XML  
     \* @param code   订单编号  
     \* @param openid 微信用户的openid  
     \* @param amount 提现金额(分)  
     \* @return  
     \*/  
private String createXml(String code, String openid, String amount) \{  
        String\[\] arr = new String\[9\];  
        arr\[0\] = "mch\_appid=" + APP\_ID;                      //商户账号appid  
        arr\[1\] = "mchid=" + MCH\_ID;                            //商户号  
        arr\[2\] = "nonce\_str=" + NONCE\_STR;            //随机字符串  
        arr\[3\] = "partner\_trade\_no=" + code;                 //订单编号  
        arr\[4\] = "openid=" + openid;                            //用户openid  
        arr\[5\] = "check\_name=NO\_CHECK";                //NO\_CHECK：不校验真实姓名  
        arr\[6\] = "amount=" + amount;//金额  
        arr\[7\] = "desc=企业付款到余额";                        //企业付款备注  
        arr\[8\] = "spbill\_create\_ip=192.168.\*\*.\*\*\*\*";        //Ip地址  
        Arrays.sort(arr);  
        String param = "";  
        for (int i = 0; i < arr.length; i++) \{  
            param += arr\[i\] + "&";  
        \}  
        param += "key=569C626880EF3EFFBB91A1E138EEC150"; //API密钥  
        String sign = MD5Util.MD5Encode(param, null).toUpperCase();  
        String xml = StringUtils.join(  
                "<xml>",  
                "<mch\_appid>" + APP\_ID + "</mch\_appid>",  
                "<mchid>" + MCH\_ID + "</mchid>",  
                "<nonce\_str>" + NONCE\_STR + "</nonce\_str>",  
                "<partner\_trade\_no>" + code + "</partner\_trade\_no>",  
                "<openid>" + openid + "</openid>",  
                "<check\_name>NO\_CHECK</check\_name>",  
                "<amount>" + amount + "</amount>",  
                "<desc>景芝云店余额提现</desc>",  
                "<spbill\_create\_ip>192.168.\*\*.\*\*\*\*</spbill\_create\_ip>",  
                "<sign>" + sign + "</sign>",  
                "</xml>"  
        );  
        return xml;  
    \}  
加密算法

import java.security.MessageDigest;

public class MD5Util \{  
    public static String MD5Encode(String origin, String charsetname) \{  
        String resultString = null;  
        try \{

            if (charsetname == null || "".equals(charsetname)) \{  
                resultString = byteArrayToHexString(md.digest(resultString  
                        .getBytes()));  
            \} else \{

            \}  
        \} catch (Exception exception) \{  
        \}  
        return resultString;  
    \}  
4、向微信请求付款

         \*/

        try \{  
            /\*\*  
             \* 此处要改

         \* \*/  
        SSLContext sslcontext = SSLContexts.custom()  
                .loadKeyMaterial(keyStore, mch\_id.toCharArray())//这里也是写密码的  
                .build();  
        // Allow TLSv1 protocol only  
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(  
                sslcontext,  
                new String\[\]\{"TLSv1"\},  
                null,  
                SSLConnectionSocketFactory.BROWSER\_COMPATIBLE\_HOSTNAME\_VERIFIER);  
        CloseableHttpClient httpclient = HttpClients.custom()  
                .setSSLSocketFactory(sslsf)  
                .build();  
        try \{  
            HttpPost httpost = new HttpPost(url); // 设置响应头信息  
            httpost.addHeader("Connection", "keep-alive");

            httpost.setEntity(new StringEntity(data, "UTF-8"));  
            CloseableHttpResponse response = httpclient.execute(httpost);  
            try \{  
                HttpEntity entity = response.getEntity();

String jsonStr = EntityUtils.toString(response.getEntity(), "UTF-8");  
                EntityUtils.consume(entity);  
                return jsonStr;  
            \} finally \{  
                response.close();  
            \}  
        \} finally \{  
            httpclient.close();  
        \}  
    \}

\}  
5、付款结果分析保存  
EnterpriceToCustomer refundResult = parseXmlToMapEnterpriceToCustomer(result);  
if (SUCCESS.equalsIgnoreCase(refundResult.getResult\_code()) && SUCCESS.equalsIgnoreCase(refundResult.getReturn\_code())) \{  
            //8表示成功  
        \} else \{  
            //9 表示失败  
        \}

如果正确会返回如下信息
