我是靠谱客的博主含糊草丛，最近开发中收集的这篇文章主要介绍页面从http://localhost:8080自动跳转到指定页面(之前的Web日历)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

注意不要把地址写成main.jsp了，这时还没有携带数据呢，写sevlet中的main

<body>

<!-- 运行javaScript不用额外安装包，自带了 -->
<script>window.location.href='main';</script>

<!--方法1-->
<!--2种写法都可以,单双引号都可以，注意不要写成了main.jsp会报空指针异常，此时jsp页面还没有携带参数！要写servlet在地址栏的映射main，如下
@WebServlet("/main")
public class Main extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {.......}
<script>window.location.href='main';</script>
<script>window.location.href="main";</script>
<script>window.location.href='http://localhost:8080/main';</script>
<script>window.location.href='success.jsp';</script>
 -->

<!--方法2-->
<!--
<script>setTimeout("location.href='main'", 0);</script>
<script>setTimeout("location.href='error.jsp'", 0);</script>
-->

</body>
</html>

测试用的2个页面

success.jsp
