java des加密是直接用des会报错：Exception in thread "main" javax.crypto.BadPaddingException: Given final block not properly padded
找了半天，只能改用另一个方式，至于两种方式的区别，就自己去官方看api了www.twitterchina.net
//Exception in thread "main" javax.crypto.BadPaddingException: Given final block not properly padded
// Cipher cipher=Cipher.getInstance("DES");
Cipher cipher = Cipher.getInstance("DES/ECB/NoPadding");
