出现这样的问题的解决办法：

1.确保struts.xml配置文件名书写正确、

2.确保struts的配置文件是在src路径下

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9"
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">


    <display-name>ComputerRoom</display-name>


    <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>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>


</web-app>

struts2的配置文件

<?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>


    <!-- 取消默认的表格布局 -->
    <constant name="struts.ui.theme" value="simple"/>
    <!-- 设置字符集  -->
    <constant name="struts.i18n.encoding" value="utf-8"/>
    <!-- 设置struts2的对象工厂为spring
    <constant name="struts.objectFactory" value="spring" />
     -->
    <constant name="struts.devMode" value="true" />
    <constant name="struts.enable.DynamicMethodInvocation" value="true"/>
<!--

通配符方式的登录Action定义 
        <action name="*LoginAction" class="loginActionBean" method="{1}"> 
            <result name="SUCCESS">WebContent/mainPage.jsp</result>
            <result name="ERROR">WebContent/index.jsp</result>
        </action> 
    
</package>
 -->  
<package name="default" namespace="/" extends="struts-default">
        <action name="success" class="com.computerRoom.action.TestAction">
            <result name="success">index.jsp</result>
        </action>
    </package>
</struts>    

解决的办法：之前index.jsp页面的路径在WebContent/WebInf路径下，我将index.jsp页面移动到WebContent路径下，这样就可以了。

总结：出现There is no Action mapped for namespace [/] and action name [] associated with context path [/computerRoom]. - [unknown location]的错误，主要是strut2.xml的配置有问题，检查struts的配置文件是否有问题，如果修改之后还是还是有问题

就查看index.jsp的文件路径是否正确
