java base64加密解密 导入哪个包

Posted 2023-03-11

参考技术A package test;
import java.io.IOException;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class Test
public static void main(String[] args)
String str = "java12345";
String ret = null;
ret = new BASE64Encoder().encode(str.getBytes());
System.out.println("加 密 前:"+str+" 加 密 后:"+ret);
str = "amF2YTEyMzQ1";
try
ret = new String(new BASE64Decoder().decodeBuffer(str));
catch (IOException e)
e.printStackTrace();

System.out.println("解 密 前:"+str+" 解 密 后:"+ret);

本回答被提问者采纳 参考技术B build path 将Jre 配置为JDK即可 参考技术C package test;
import java.io.IOException;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class Test
public static void main(String[] args)
String str = "java12345";
String ret = null;
ret = new BASE64Encoder().encode(str.getBytes());
System.out.println("加前:"+str+" 加后:"+ret);
str = "amF2YTEyMzQ1";
try
ret = new String(new BASE64Decoder().decodeBuffer(str));
catch (IOException e)
e.printStackTrace();

System.out.println("解前:"+str+" 解后:"+ret);
