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 {

/**

@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;
}
/**

@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;
}

}
