java自动登陆JSP网站

有httpunit这个框架可以实现,代码如下
import java.io.IOException;
import java.net.MalformedURLException;

import org.xml.sax.SAXException;

import com.meterware.httpunit.GetMethodWebRequest;
import com.meterware.httpunit.PostMethodWebRequest;
import com.meterware.httpunit.WebConversation;
import com.meterware.httpunit.WebRequest;
import com.meterware.httpunit.WebResponse;

public class LoginTest {
/**
* form的get方法登录
* @throws MalformedURLException
* @throws IOException
* @throws SAXException
*/
public void getMethod() throws MalformedURLException, IOException, SAXException{
// 建立一个WebConversation实例
WebConversation wc = new WebConversation();
// 向指定的URL发出请求
WebRequest req = new GetMethodWebRequest( " http://localhost:8080/book/adminLogin " );
// 给请求加上参数
