java使用Base64编码实例

本文实例为大家分享了java使用base64编码的具体代码，供大家参考，具体内容如下

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 {


 
 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;
 }


 
 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;
 }

}
