这里系统采用偷懒的方式，只是在package的namespace为"/hello"下面查看是否有name为“hello/sum”的action，没有，就会显示上述警告，而实际运行时，会解析action的路径来查找对应的jsp页面，所以不会影响系统运行。

原始jsp代码:

求代数和. <br>
<s:form action = "hello/sum" method = "post">
<s:textfield name = "v1" label = "操作数1"/>
<s:textfield name = "v2" label = "操作数2"/>
<s:submit value = "求和"/>
</s:form>

struts.xml:

<package name="default" namespace="/hello" extends="struts-default">
<action name="test" class="com.lijie.test.HelloWorld">
<result name = "success" type="dispatcher">/hello.jsp</result>
<result name = "positive">/positive.jsp</result>
<result name = "negative">/negative.jsp</result>
</action>
<action name="sum" class="com.lijie.test.FirstAction">
<result name = "positive">/positive.jsp</result>
<result name = "negative">/negative.jsp</result>
</action>
</package>

若要让上述警告消失，修改jsp中的form标签的属性：

<s:form action = "sum" method = "post" namespace = "/hello">
这样系统可以在/hello下查找到name为sum的action，就不会出现警告信息了。
