java使用Base64编码

Test Base64

package com.weiwen.provider.utils;
import java.io.IOException;

import com.alibaba.fastjson.JSON;
import lombok.extern.slf4j.Slf4j;
import org.junit.Test;

import sun.misc.BASE64Encoder;
import sun.misc.BASE64Decoder;
@Slf4j
public class Base64  {

        @Test
        public void testBase64() throws IOException {
            // BASE64编码
            String s = "1f2bc1970a2eb19aabc0f94acea922717a1ae998603ff0593baff";
            BASE64Encoder encoder = new BASE64Encoder();
            s = encoder.encode(s.getBytes("UTF-8"));
//            System.out.println(s);
            log.info("BASE64编码为：{}", JSON.toJSONString(s));

           // BASE64解码
            BASE64Decoder decoder = new BASE64Decoder();
            byte[] bytes = decoder.decodeBuffer(s);
//            System.out.println(new String(bytes, "UTF-8"));
            log.info("BASE64解码为：{}", JSON.toJSONString(new String(bytes, "UTF-8")));
        }
    }

Base64工具类

package com.weiwen.provider.utils;
import java.io.IOException;

import com.alibaba.fastjson.JSON;
import lombok.extern.slf4j.Slf4j;
import org.junit.Test;

import sun.misc.BASE64Encoder;
import sun.misc.BASE64Decoder;
@Slf4j
public class Base64  {


    /**
     * Base64 编码
     * @param encodeText
     * @return
     * @throws IOException
     */
    public static String base64Encode(String encodeText) throws IOException{
        BASE64Encoder encoder = new BASE64Encoder();
        String str = encoder.encode(encodeText.getBytes("UTF-8"));
        log.info("BASE64编码为：{}", JSON.toJSONString(str));
        return str;
    }


    /**
     * Base64 解码
     * @param decodeText
     * @return
     * @throws IOException
     */
    public static byte[] base64Decode(String decodeText) throws IOException{
            BASE64Decoder decoder = new BASE64Decoder();
            byte[] bytes = decoder.decodeBuffer(decodeText);
            log.info("BASE64解码为：{}", JSON.toJSONString(new String(bytes, "UTF-8")));
            return bytes;
    }

}
