There is no Action mapped for action name hello. - [unknown location

看看struts.xml 下有没有这个hello action

[渭水飞熊]

看错误报，原因是Action没有配置到Struts配置文件中，你得说清楚，你的具体环境是什么。比如你使用的是XML的配置方式还是注解的配置方式。这样大家好帮你分析啊。

[inewzone]

求看一下的jar与struts2的配置文件。。。其实很多时候就是这两个引起的

[dryZeng]

除了上面的些原因外，还有一个原因。

就是检查一下你页面的form里所有name是否和action里的变量是否对应，变量类型是否一致。

比如，如果你action中有个变量叫public Integer userid，那么在form中的这个userid不能输入中文.

[kobe__java]

There is no Action mapped for action name hello 这里写了，应该是struts配置里没有对应的name="hello" class="......";

[dryZeng]

还有，楼主一个贴都没结吗？

[安静的洋葱]

建议楼主先检查看看struts配置文件是否配置正确

[昨日凡阳]

hello.do，你的struts配置文件中，path是否有/hello这样的mapping？

[xieshengjun2009]

仔细检查代码！

[不关橙猫猫事的哦]

There is no Action mapped for action name hello

有木有<action name="hello" class="xxx"></action>

[cxw3152]

应该是在对应的配置文件中没有找到相应的result 例如<result name="updateTypeInfo">
<param name="includeProperties">message</param>
</result>
name="updateTypeInfo"中的updateTypeInfo就是你返回的字符串

[cxw3152]

给你一个配置的问题
<action name="cdmcategory"
class="com.bossy.web.action.CdmCategoryAction">
<result type="json">
<param name="root">nodeLists</param>
</result>
<result type="json" name="saveTypeInfo">
<param name="includeProperties">message</param>
</result>
<result type="json" name="deleteTypeInfo">
<param name="includeProperties">message</param>
</result>
<result type="json" name="updateTypeInfo">
<param name="includeProperties">message</param>
</result>
<result type="json" name="loadTypeInforToPaixu">
<param name="root">extJsPageBean</param>
</result>
<result type="json" name="paixuTypeInfo">
<param name="includeProperties">message</param>
</result>
</action>
