参考网上做的一个Ajax+jsp+servlet的一个简单示例

不多说，一切尽在代码中

首先 jsp页面代码：

?
public class AjaxServlet extends HttpServlet {/** *  */private static final long serialVersionUID = 1L;@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse resp)throws ServletException, IOException {resp.setContentType("text/html;charset=utf-8");resp.setHeader("Cache-Control", "no-cache");PrintWriter out=resp.getWriter(); //String email=request.getParameter("mailAddress");if(email.equals("12345678@163.com"){ out.writer("数据库中有该邮箱");}else out.writer("无该邮箱");out.close();}@Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {this.doGet(req, resp);}}
