Java base64 编码、解码

public class uploadServletTest {

    @Test
    public void name() throws IOException {

        String content = "这里是Base64编码的内容";

        //编码
        BASE64Encoder base64Encoder = new BASE64Encoder();
        String encodeStr = base64Encoder.encode(content.getBytes("utf-8"));
        System.out.println(encodeStr);

        //解码
        BASE64Decoder base64Decoder = new BASE64Decoder();
        byte[] bytes = base64Decoder.decodeBuffer(encodeStr);
        String s = new String(bytes, "utf-8");
        System.out.println(s);
    }
}
