UnknownHostException：如何通过java应用程序解决UnknownHostException

Question

我正在尝试连接到URL并使用java代码从URL读取/下载内容。 我面临以下例外。

Exception in thread "main" java.net.UnknownHostException: myURL

代码：

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class GetURLContent {
    public static void main(String[] args) {

        URL url;

        try {
            // get URL content
            url = new URL("https://myURL");
            URLConnection conn = url.openConnection();
            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String inputLine;

            //save to this filename
            String fileName = "C:/data/test.html";
            File file = new File(fileName);
            if (!file.exists()) {
                file.createNewFile();
            }
            //use FileWriter to write file
            FileWriter fw = new FileWriter(file.getAbsoluteFile());
            BufferedWriter bw = new BufferedWriter(fw);
            while ((inputLine = br.readLine()) != null) {
                bw.write(inputLine);
            }

            bw.close();
            br.close();
            System.out.println("Done");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

我是否需要在我的应用程序或代理设置中设置任何内容来解决此错误。任何建议都会有所帮助。
