这篇文章主要介绍了java使用Base64编码，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
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
