三、表单请求Servlet处理

2010-11-06 11:44 330 查看

一、表单的Form代码

二、编写Servlet
1.MyEclipse新建一个Servlet

2.名字SecondServlet，选择doget和dopost方法
3.选择同时web.xml内容,Display Name和Description方框内容可以不要。点击"finish"

web.xml会自动生成SecondServlet的配置

4.更改SecondServlet的方法

protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
process(req, resp);
}

protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
process(req, resp);
}

protected void process(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String name=req.getParameter("usernaem");
String pass=req.getParameter("password");
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<HTML><HEAD><TITLE>My First Servlet</TITLE></HEAD>");
out.println("<BODY>");
out.println("You name is :" + name + " You password is:" + pass);
out.println("</BODY></HTML>");
}
