java使用BASE64编码器编码和解码

1. 编码

String content="这是bas64的编码内容";
base64Encoder base64Encoder = new base64Encoder();
String encode = base64Encoder.encode(content.getBytes(StandardCharsets.UTF_8));
System.out.println(encode);

2. 解码

base64Decoder base64Decoder = new base64Decoder();
byte[] bytes = base64Decoder.decodeBuffer(encode);
String s = new String(bytes, "utf-8");
System.out.println(s);
