struts-Action-Names

<action name="Logon" class="tutorial.Logon">
  <result type="redirectAction">Menu</result>
  <result name="input">/Logon.jsp</result>
</action>

注：（1）在web项目中，匹配action时，去掉请求路径中的host和项目的名字，只匹配name

In a web application, the name attribute is matched as part of the location requested by a browser (or other HTTP client). The framework will drop the host and application name and the extension and match what's in the middle: the action name. So, a request for http://www.planetstruts.org/struts2-mailreader/Login.do will map to the  Logon action.

（2）使用Struts标签时，form中可以直接写action的name

Within an application a link to an action is usually generated by a Struts Tag. The tag can specify the action by name, and the framework will render the default extension and anything else that is needed. Forms may also submit directly to a Struts Action name (rather than a "raw" URI).

（3）如果action中会出现“/”，需要配置 <constant name="struts.enable.SlashesInActionNames" value="true"/>

Action Names With Slashes

If your action names have slashes in them (for example, <action name="admin/home" class="tutorial.Admin"/>) you need to specifically allow slashes in your action names via a constant in thestruts.xml file by specifying <constant name="struts.enable.SlashesInActionNames" value="true"/>. 

（4）action的name使用驼峰表示

Action Names with Dots and Dashes
Although action naming is pretty flexible, one should pay attention when using dots (eg. create.user) and/or dashes (eg. my-action). While the dot notation has no known side effects at this time, the dash notation will cause problems with the generated JavaScript for certain tags and themes. Use with caution, and always try to use camelcase action names (eg. createUser) or underscores (eg. my_action).
