base64编码变换

base64编码转换

在高并发下，正确的做法如下：

/** ??*?BASE64解密 ??*? ??*?@param?key ??*?@return ??*?@throws?Exception ??*/??public?static?String?decryptBASE64(String?key)?throws?Exception?{ ?? ????if(key==null||key.length()<1){ ?? ????????return?""; ?? ????} ??????return?new?String(new?BASE64Decoder().decodeBuffer(key)); ?? } ????/** ??*?BASE64加密 ??*? ??*?@param?key ??*?@return ??*?@throws?Exception ??*/??public?static?String?encryptBASE64(String?key)?throws?Exception?{ ?? ????if(key==null||key.length()<1){ ?? ????????return?""; ?? ????} ??????return?new?String(new?BASE64Encoder().encodeBuffer(key.getBytes())); ?? }
