MD5Util 方法
package com.funcanteen.business.action.pay.util;
import java.security.MessageDigest;
public class MD5Util {
private static String byteArrayToHexString(byte b[]) {
StringBuffer resultSb = new StringBuffer();
for (int i = 0; i < b.length; i++)
resultSb.append(byteToHexString(b[i]));
return resultSb.toString();
}
private static String byteToHexString(byte b) {
int n = b;
if (n < 0)
n += 256;
int d1 = n / 16;
int d2 = n % 16;
return hexDigits[d1] + hexDigits[d2];
}
public static String MD5Encode(String origin, String charsetname) {
String resultString = null;
try {
resultString = new String(origin);
MessageDigest md = MessageDigest.getInstance("MD5");
if (charsetname == null || "".equals(charsetname))
resultString = byteArrayToHexString(md.digest(resultString
.getBytes()));
else
resultString = byteArrayToHexString(md.digest(resultString
.getBytes(charsetname)));
} catch (Exception exception) {
}
return resultString;
}
private static final String hexDigits[] = { "0", "1", "2", "3", "4", "5",
"6", "7", "8", "9", "a", "b", "c", "d", "e", "f" };
}
2：签名封装方法
//设置签名
public String getSignature(Map<String, String> map){
StringBuffer sb = new StringBuffer();
for(Map.Entry<String, String> me :map.entrySet()){
sb.append(me.getKey()).append("=").append(me.getValue()).append("&");
}
sb.append("key=").append("xxxxxxxxxxxxxxxxxxxx");
return MD5Util.MD5Encode(sb.toString(), null);
}
3:调用签名方法
//要发送给用户的模板信息
TreeMap<String, String> josnMap = new TreeMap<String,String>();
josnMap.put("name", stallApply.getAccountName());
String jsonData = JSON.toJSONString(josnMap);
//封装组装签名
Map<String, String> map = new TreeMap<String,String>();
String timestamp = System.currentTimeMillis()/1000+"";
map.put("json", jsonData);
map.put("mobile", stallApply.getMobile());
map.put("templateCode", "SMS_74665033");
map.put("timestamp",timestamp);
String signature = getSignature(map).toUpperCase();//字母转成大写
