java 中的编码与解码

package com.sunplus.app;

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;

public class Encode {

    public static void main(String[] args) {
        String keyWord = "小张";
        try {
            String encodeBefore = URLEncoder.encode(keyWord, "utf-8");
            System.out.println("编码前：" + encodeBefore);
            String encodeEnd = URLDecoder.decode(keyWord, "utf-8");
            System.out.println("解码：" + encodeEnd);
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

 

编码前：%E5%B0%8F%E5%BC%A0
解码：小张
