struts2.0 零配置
查找
Actions
在web.xml中设置Actions包过滤器的参数时，如果多个用逗号隔开，包和子包将被自动扫描。所有在包里注册的继承Action接口或以Action结尾的类和子类将被检查。
例如：
<filter>
<filter-name> struts2 </filter-name>
<filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class>
<init-param>
<param-name> actionPackages </param-name>
<param-value> com.foo.bar,com.baz.quux </param-value>
</init-param>
</filter>
<filter-name> struts2 </filter-name>
<filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class>
<init-param>
<param-name> actionPackages </param-name>
<param-value> com.foo.bar,com.baz.quux </param-value>
</init-param>
</filter>
事例：
Showcase中的例子
- Web.xml中的一部分：
<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>org.apache.struts2.showcase.person</param-value>
</init-param>
</filter>
- struts-person.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
<!-- START SNIPPET: xworkSample -->
<struts>
<package name="person" extends="struts-default" namespace="/person" />
</struts>
<!--END SNIPPET: xworkSample -->
- person/index.jsp

<li><a href="listPeople.action">List</a> all people</li>
