package key;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class t1 extends HttpServlet{
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
super.doGet(req, resp);
}

}
为什么后台捕获不到前台传递的值呢。。。才学JAVA 不是很懂

[解决办法]
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub

String name = req.getParameter("name") ;
String password = req.getParameter("password") ;

String pwd = req.getParameter("pwd") ;

System.out.println("name = " + name + ", password = " + password + " , pwd = " + pwd) ;

}
