Question

我正在开发tomcat上的spring mvc应用程序。问题是tomcat每隔2/3分钟刷新页面，我看不出原因！我的配置是

的web.xml

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

服务器无法自行刷新页面，没有简单的方法来实现。如果你真的遇到过这样的行为，那么你的代码中的某个地方你有一个显式刷新（可能是重定向？JavaScript可能？）或者AJAX正在强制页面重新加载。

请注意我说的“简单方法”。你可以通过更复杂的技术来做到这一点，但你不太可能这样做。

Answer 2

你有一个：

<meta http-equiv="refresh" content="240" />

页眉中的

，表示您告诉浏览器每4分钟（240秒）刷新一次页面。

作为一个额外的观察，你还在渲染主页时创建一个会话，这可能是一个不必要的开销。

为什么tomcat会永久刷新页面
