11         byte[] b = name.getBytes("utf-8");
12         String encode = Base64.encodeBase64String(b);
13         String decode = new String(Base64.decodeBase64(encode));
14         byte[] decode2 = Base64.encodeBase64(b);
15         byte[] decode3 = Base64.decodeBase64(decode2);
16         System.out.println(encode);
17         System.out.println(decode);
