关于struts2找不到action

刚才小弟做了次上传拦截除图片外的其他东西，修改了web.xml和struts2.xml报错以后，我就Ctrl+z还原回来了。可是悲剧了找不到action了，所有action都毛笔了。
struts.xml <action name="picNews_*" class="picNewsAction" method="{1}">
<result name="findPNAll">/picNews/picNews.jsp</result>
<result name="blockall">/picNews/picNews_block.jsp</result>
<result name="cblockall">/picNews/picNews_cblock.jsp</result>
<result name="newsAll">/picNews/picNews_news.jsp</result>
<result name="picnews">/picNews/updatePicNews.jsp</result>
<result>/test.jsp</result>
</action>web.xml<?xml version="1.0" encoding="UTF-8"?>
