7,用来服务注册的servlet regist.java

package servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;

import dao.userdata;
@WebServlet(urlPatterns={"/regist"})
public class regist extends HttpServlet{
userdata dao;

@Override
public void service(ServletRequest req, ServletResponse res)
throws ServletException, IOException {
req.setCharacterEncoding("GBK");
String name=req.getParameter("name");
String pass=req.getParameter("password");
dao=userdata.getdao();
dao.regist(name, pass);
req.getRequestDispatcher("login.jsp").forward(req, res);
}

}
