URLEncoder和URLDecoder转码

目前看是为了解决网络传输的中文乱码问题

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
public class URLDecoderTest {
public static void main(String[] args) throws UnsupportedEncodingException {
// 将application/x-www-from-urlencoded字符串转换成普通字符串
        String keyWord = URLDecoder.decode("%E6%9D%8E%E5%88%9A", "UTF-8");
        System.out.println(keyWord);
// 将普通字符创转换成application/x-www-from-urlencoded字符串
        String urlString = URLEncoder.encode("爱我中华", "UTF-8");
        System.out.println(urlString);
    }
}
