我需要一个使用 Google Translation API 将西班牙语转换为英语的示例。我尝试使用以下代码。它给出了一些例外。有人可以帮助我吗？

代码 ：

import  com.google.api.translate.*;
public class GoogleTranslator {

    /**
     * @param args

    */
    @SuppressWarnings("deprecation")
    public static void main(String[] args) {// TODO code application logic here


            try {
                Translate.setHttpReferrer("sp-en");
                String translatedText = Translate.translate("Hola mundo", Language.SPANISH, Language.ENGLISH);
                System.out.println(translatedText);
                } catch (Exception ex) {
                ex.printStackTrace(); }

    }
}

错误 ：

你需要弄清楚为什么你没有到达这个主机：ajax.googleapis.com

例外说：

 java.net.UnknownHostException: ajax.googleapis.com

javadoc 说抛出 UnknownHostException 表示无法确定主机的 IP 地址。

你应该你的DNS。

nslookup ajax.googleapis.com

Set your DNS to google one

if on linux machine

sudo gedit /etc/resolv.conf

add 

nameserver 8.8.8.8
nameserver 8.8.4.4

or if on windows goto network setting and set DNS for active connection

您没有 api 密钥，例如 GoogleAPI.setKey(); 我想你需要这样的东西才能继续
