exception

因此，它显示容器找不到 addUserAction。但是，请查看我的 struts.xml 和 applicationContext.xml：

struts.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<constant name="struts.objectFactory" value="spring"/>
<include file="struts-default.xml"></include>
<package name="default" extends="struts-default">
 <action name="addUser" class="addUserAction">
    <result name="success">/add_success.jsp</result>
    <result name="error">/add_error.jsp</result>
  </action>
</package>
</struts>

applicationContext.xml 的一部分：

<bean id="userService" class="com.rainbow.service.impl.UserServiceImpl">
        <property name="userDAO" ref="userDAO"></property>
    </bean>
<bean id="addUserAction" class="com.rainbow.action.AddUserAction" scope="prototype">
        <property name="userService" ref="userService"></property>
    </bean>

很明显 addUserAcion 是“com.rainbow.action.AddUserAction”，所以我找不到原因，希望有人能帮助我，非常感谢！

你在类路径中有所有必要的 jar 文件吗？你有struts2-spring-plugin jar 文件吗？
