这个是Struts.xml的配置
<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="importdata-*" class="com.imooc.drdc.action.ImportDataAction" method="{1}">
<result>/jsp/importList.jsp</result>
</action>
<action name="download" class="com.imooc.drdc.action.FileDownloadAction">
<result name="success" type="stream">
<param name="contentType">application/octet-stream</param>
<param name="inputName">inputStream</param>
<param name="contentDisposition">attachment;filename="${downloadFileName}"</param>
<param name="bufferSize">8192</param>
</result>
</action>
</package>
</struts>

ImportDataAction路径也没发现有什么问题

[孟子E章]

错误说没有找到
com.imooc.drdc.action.ImportDataAction
这个类，确认编译成功了，
并
:/Java/Tomcat8/webapps/excel_web_drdc/WEB-INF/classes/子文件夹下面有这个类ImportDataAction.class
注意不要有拼写错误和大小写错误

[飘落的羽毛]

有的，但是不知为什么还是有问题

[飘落的羽毛]

额，我发现了，类名出了个小问题，谢谢啦

[飘落的羽毛]

现在有个问题，我的myeclips没有对这些.java的进行编译
