  这篇文章主要为大家详细介绍了微信支付java版本之Native付款,感兴趣的小伙伴们可以参考一下

  最近工作中接触到一些关于微信支付方面的东西,看到给的DEMO都是PHP版本的,再加上微信支付文档写的确实不敢恭维,趟过不少坑之后闲下来做个总结。
  
  一、前期准备
  
  做微信开发首先要申请一个公共账号,申请成功后会以邮件形式发给你一些必要信息,公共账号中有开发文档以及开发中必要信息,以及测试的数据查询。

  二、工具类
  
  1.MD5加密工具类
  1. package com.pay.utils.weixin;
  2. import java.security.MessageDigest;
  3. public class MD5Util {
  4. public final static String MD5(String s) {
  5.     char hexDigits[]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};   
  6.     try {
  7.       byte[] btInput = s.getBytes();
  8.       // 获得MD5摘要算法的 MessageDigest 对象
  9.       MessageDigest mdInst = MessageDigest.getInstance("MD5");
  10.       // 使用指定的字节更新摘要
  11.       mdInst.update(btInput);
  12.       // 获得密文
  13.       byte[] md = mdInst.digest();
  14.       // 把密文转换成十六进制的字符串形式
  15.       int j = md.length;
  16.       char str[] = new char[j * 2];
  17.       int k = 0;
  18.       for (int i = 0; i < j; i++) {
  19.         byte byte0 = md[i];
  20.         str[k++] = hexDigits[byte0 >>> 4 & 0xf];
  21.         str[k++] = hexDigits[byte0 & 0xf];
  22.       }
  23.       return new String(str);
  24.     } catch (Exception e) {
  25.       e.printStackTrace();
  26.       return null;
  27.     }
  28. }
  29. }

  2.CommonUtil工具类,用于装换成微信所需XML。以下return new String(xml.toString().getBytes(),"ISO8859-1");将工具类中的utf-8改成iso8859-1,否则微信订单中的中文会出现乱码,改后可以正确显示。
