Base64和(BASE64Encoder/BASE64Decoder）比较

一、jdk1.8下的 BASE64Encoder 和 BASE64Decoder(JDK9开始已移除):

package com.lmp.utils;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class test {
    public static void main(String[] args) throws Exception {

        String str = "hello word";
        BASE64Encoder base64Encoder = new BASE64Encoder();
        // JDK1.8 BASE64Encoder 加密
        String encode = base64Encoder.encode(str.getBytes());
        System.out.println(encode);

        BASE64Decoder base64Decoder = new BASE64Decoder();
        // JDK1.8 BASE64Decoder 解密
        byte[] bytes = base64Decoder.decodeBuffer(encode);
        String res = new String(bytes);
        System.out.println(res);

    }

}

二、推荐使用Base64：

package com.lmp.utils;

import java.util.Base64;

public class test {
    public static void main(String[] args) throws Exception {

        String str = "hello word";
        // JDK1.8 Base64加密
        String encode = Base64.getEncoder().encodeToString(str.getBytes());
        System.out.println(encode);

        // JDK1.8 Base64解密
        byte[] bytes = Base64.getDecoder().decode(encode);
        String res = new String(bytes);
        System.out.println(res);
    }

}

参考: JDK从1.8升级到9.0.1后.BASE64Decoder和.BASE64Encoder不可用.
