知道各位对sign比较头痛，我上方法
public static String getSign(Object o) throws IllegalAccessException {
ArrayList<String> list = new ArrayList<String>();
Class cls = o.getClass();
Field[] fields = cls.getDeclaredFields();
for (Field f : fields) {
f.setAccessible(true);
if (f.get(o) != null && f.get(o) != "") {
list.add(f.getName() + "=" + f.get(o) + "&");
}
}
int size = list.size();
String [] arrayToSort = list.toArray(new String[size]);
Arrays.sort(arrayToSort, String.CASE_INSENSITIVE_ORDER);
StringBuilder sb = new StringBuilder();
for(int i = 0; i < size; i ++) {
sb.append(arrayToSort[i]);
}
String result = sb.toString();
result += "key=" + Configure.getKey();
result = MD5.MD5Encode(result).toUpperCase();
return result;
}
用java反射的，适合所有class
祝各位成功！
