eclipse中配置struts2时报：
Eclipse中配置Struts2出现There is no Action
mapped for action name loginAction. - [unknown location]
错误
做如下检查：
1、确保struts.xml文件名大小写正确：struts.xml(全部小写，我就是这里出错了)
2、确保struts.xml文件在src目录下（很重要！后面就着重说这个）
附：
web.xml

错误总结：
1. struts.xml中的 <action>标签name="LoginAction"要与 index.jsp中 <form>标签action="LoginAction" 一致；
2. struts.xml中的 <package>标签namespace="/"要与 index.jsp中 <form>标签namespace="/" 一致；
3. 配置好后若有修改重启一下服务器；
