Base64编码和解码

使用jdk自带jar

package demo;

import java.io.IOException;
import java.io.UnsupportedEncodingException;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class Base64EncodeAndDecode {
	public static void main(String[] args) {
		String temp = "你好，我叫tom";
		BASE64Encoder encoder = new BASE64Encoder();
		BASE64Decoder decoder = new BASE64Decoder();
		try {
			temp = encoder.encode(temp.getBytes("utf-8"));
			System.out.println(temp);
			byte[] tempByte = decoder.decodeBuffer(temp);
			temp = new String(tempByte, "utf-8");
			System.out.println(temp);
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
