微信支付java版本之Native付款
更新時(shí)間：2016年08月04日 14:19:28 作者：wangxuewei111
這篇文章主要為大家詳細(xì)介紹了微信支付java版本之Native付款，感興趣的小伙伴們可以參考一下
最近工作中接觸到一些關(guān)于微信支付方面的東西，看到給的DEMO都是PHP版本的，再加上微信支付文檔寫的確實(shí)不敢恭維，趟過(guò)不少坑之后閑下來(lái)做個(gè)總結(jié)。
一、前期準(zhǔn)備
做微信開發(fā)首先要申請(qǐng)一個(gè)公共賬號(hào)，申請(qǐng)成功后會(huì)以郵件形式發(fā)給你一些必要信息，公共賬號(hào)中有開發(fā)文檔以及開發(fā)中必要信息，以及測(cè)試的數(shù)據(jù)查詢。
二、工具類
1.MD5加密工具類
package com.pay.utils.weixin;
import java.security.MessageDigest;
public class MD5Util {
public final static String MD5(String s) {
char hexDigits[]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
try {
byte[] btInput = s.getBytes();
// 獲得MD5摘要算法的 MessageDigest 對(duì)象
MessageDigest mdInst = MessageDigest.getInstance("MD5");
// 使用指定的字節(jié)更新摘要
mdInst.update(btInput);
// 獲得密文
byte[] md = mdInst.digest();
// 把密文轉(zhuǎn)換成十六進(jìn)制的字符串形式
int j = md.length;
char str[] = new char[j * 2];
int k = 0;
for (int i = 0; i < j; i++) {
byte byte0 = md[i];
str[k++] = hexDigits[byte0 >>> 4 & 0xf];
str[k++] = hexDigits[byte0 & 0xf];
}
return new String(str);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
2.CommonUtil工具類，用于裝換成微信所需XML。以下return new String(xml.toString().getBytes(),"ISO8859-1");將工具類中的utf-8改成iso8859-1,否則微信訂單中的中文會(huì)出現(xiàn)亂碼，改后可以正確顯示。
package com.pay.utils.weixin;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.util.*;
import java.util.Map.Entry;
public class CommonUtil {
public static String CreateNoncestr(int length) {
String chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
String res = "";
for (int i = 0; i < length; i++) {
Random rd = new Random();
res += chars.indexOf(rd.nextInt(chars.length() - 1));
}
return res;
}
public static String CreateNoncestr() {
String chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
String res = "";
for (int i = 0; i < 16; i++) {
Random rd = new Random();
res += chars.charAt(rd.nextInt(chars.length() - 1));
}
return res;
}

}
if (buff.isEmpty() == false) {

}
} catch (Exception e) {
throw new SDKRuntimeException(e.getMessage());
}
return buff;
}
public static boolean IsNumeric(String str) {
if (str.matches("\\d *")) {
return true;
} else {
return false;
}
}
public static String ArrayToXml(HashMap<String, String> arr) {
