我在类路径中添加了以下 jar 文件：

• commons-beanutils-1.8.0.jar
• commons-chain-1.2.jar
• commons-collections-3.1.jar
• commons-digester-2.0.jar

• xwork-core-2.3.4.1.jar
• javassist-3.11.0.GA.jar
• ognl-3.0.5.jar

网页.xml：

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
</filter>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

我已经关注了这个线程，但没有成功。

请帮忙。

有点奇怪。你有所有的罐子，但你可以尝试使用它web.xml来使用 version 2.4。我正在使用带有tomcat 7的netbeans。

<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping> </web-app>

但是，您可以查看 apache 日志以找到确切的问题，如下所示：

Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringUtils
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1711)
