Struts问题确实让我很烦啊，调好了这个bug，出现下面这个bug，这个有事刚刚弄了一下午的问题。
查找了许多答案，
大致的解决方法如下
1：注意Struts.xml文件的位置，必须在src目录之下
2：
1 <!DOCTYPE struts PUBLIC 2 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 3 "http://struts.apache.org/dtds/struts-2.3.dtd">
这里面的Struts—2.3.dtd必须与自己的tomcat版本相一致。
3：
1 <struts> 2 <constant name="struts.devMode" value="true" /> 3 <package name="exercise" extends="struts-default" namespace="/" >
在struts文件中开发模式必须默认为true
最后发现虽然我的struts.xml文件位于src文件之下，但是
struts.xm位于src下是为了编译后能找到struts配置文件，必须确保其在WEB-INF之下
更改eclipse web 项目默认编译输出路径：
eclipse中只能针对项目更改，因为其默认的是build目录下的，只能以项目更改：
项目右键 -》properties -》Java Build Path -》source -》Default output folder，选择你的路径，ok！
