刚开始使用Struts2。我认为使用 struts2 原型是个好主意，但它似乎已经过时了。当我运行我的项目时，我不断收到以下警告：

ActionContextCleanUp <<< is deprecated! Please use the new filters!

这是我当前的 web.xml 文件：

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

    </welcome-file-list>

</web-app>

我要改变什么来摆脱警告？

想通了。在查看了 sitemesh 插件的这个示例web.xml 文件后，我最终得到了一个可以工作的 web.xml 文件。以下是其他遇到此问题的人的样子：

<display-name>Test</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

</web-app>

现在那个警告消失了。

您可以删除过滤器 action2-cleanup。

<filter>
    <filter-name>action2-cleanup</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
</filter>
