我是Struts的新手，我遇到了这样的问题

我的struts.xml文件中还有一些probs

<?xml version="1.0" encoding="UTF-8" ?>**
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="false" />
    <constant name="struts.custom.i18n.resources" value="AppResources" />
    <package name="default" extends="struts-default" namespace="/">
        <action name="login"
            class="sturts2.LoginAction">
            <result name="success">Welcome.jsp</result>
            <result name="error">Login.jsp</result>
        </action>
    </package>
</struts>

在struts.xml的第一行，我得到了这样的错误：

引用文件包含错误（http://struts.apache.org/dtds/struts-2.0.dtd）。有关详细信息，请右键单击“问题视图”中的消息，然后选择“显示详细信息...”

这对我有用：

将所有必要的jar文件复制到WebContent＆gt; WEB-INF＆gt; lib文件夹
确保您添加了 commons-lang3-3.1 和 struts2-core-2.3.16.3

java.lang.ClassNotFoundException：org.apache.struts2.dispatcher.FilterDispatcher
