Java URLEncoder URLDecoder

URLDecoder 和 URLEncoder 用于完成普通字符串 和 application/x-www-form-urlencoded MIME 字符串之间的相互转换

URLDecoder类包含一个decode(String s,String enc)静态方法，它可以将application/x-www-form-urlencoded MIME字符串转成普通字符串；

URLEncoder类包含一个encode(String s,String enc)静态方法，它可以将普通字符串转换成application/x-www-form-urlencoded MIME字符串。

        logger.info(URLEncoder.encode(str2, "gbk"));
        logger.info(URLEncoder.encode(str2, "utf-8"));
