    //获得请求的参数。
    String id=request.getParameter("userid");
    String psw=request.getParameter("password");
    //连接数据库
    Class.forName("org.gjt.mm.mysql.Driver").newInstance();
    Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/rsm?user=root&password=&useUnicode=true&characterEncoding=gbk");
    Statement stmt=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);   
    String isCorrect="select * from user_info where username='"+id+"' and password='"+psw+"'";
    ResultSet result=stmt.executeQuery(isCorrect);
    session.setAttribute("isLog",new String("0"));if(!result.next())
    {
    response.sendRedirect("error.jsp");//账号或密码错误，转入错误页面
    result.close();
    stmt.close();
    con.close();
    }
    else
    {
      session.setAttribute("userid",result.getString("userid"));
      session.setAttribute("username",result.getString("username"));  
      session.setAttribute("password",result.getString("password"));
      session.setAttribute("email",result.getString("email"));
      session.setAttribute("usertype",new Integer(result.getString("usertype")));   
      session.setAttribute("isLog",new String("1"));
      session.setAttribute("point",new Integer(result.getInt("point")));   
      stmt.close();
      con.close(); 
      response.sendRedirect("../index.jsp");
    }
    %>
