Struts2中Action配置

<!--
方案一:一个action对应一个方法;
-->

<action name="add" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall" method="add">
<result>/views/kp02_action/action.jsp</result>
</action>
<action name="delete" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall" method="delete">
<result>/views/kp02_action/action.jsp</result>
</action>
<action name="update" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall" method="update">
<result>/views/kp02_action/action.jsp</result>
</action>
<action name="query" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall" method="query">
<result>/views/kp02_action/action.jsp</result>
</action>

<!--
方案二: 动态方法调用(DMI)
DMI: Dynamic Method Invocation
http://host:port/contextPath/namespace/actionName!methodName
-->
　　　　　　　　　　注意:一般动态方法调用都默认为false,首先要设置为true
　　　　　　　　　　<constant name="struts.enable.DynamicMethodInvocation" value="true"/>

<action name="call" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall">
<result>/views/kp02_action/action.jsp</result>
</action>
<!--
方案三: 通配符(Wildcard)
把当前请求过来的地址进行过滤, 凡是以call_为actionName的请求都通过, 把请求地址中*所代表的
所有字符串放在后面的属性的值中, 值使用{}
-->
<action name="call_*" class="com.gxxy.struts.kp03_methodcall.MultiMethodCall" method="{1}">
<result>/views/kp02_action/action.jsp</result>
</action>
<action name="test_*" class="com.gxxy.struts.kp03_methodcall.TestCall" method="{1}">
<result>/views/kp02_action/action.jsp</result>
</action>
<action name="*_*" class="com.gxxy.struts.kp03_methodcall.{1}Call" method="{2}">
<result>/views/kp02_action/action.jsp</result>
</action>
<!-- http://localhost/struts/method/Test_update -->
