struts2动态方法调用和使用通配符定义action

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<package name="employee" extends="struts-default" namespace="/control/employee">
		<action name="add" class="blog.action.HelloWorld" method="execute" >
			<result name="success">/WEB-INF/page/addEmployee.jsp</result>
			<result name="message">/WEB-INF/page/message.jsp</result>
		</action>
		
		<action name="operation_*" class="blog.action.HelloWorld" method="{1}" >
			<result name="success">/WEB-INF/page/addEmployee.jsp</result>
			<result name="message">/WEB-INF/page/message.jsp</result>
		</action>
	</package>
</struts>

HelloWorld.java类中有两个方法：execute()和add()

则通过动态方法访问的方式为：

http://localhost:8080/struts2/control/employee/add!execute

和

http://localhost:8080/struts2/control/employee/add!add

通过通配符的方式访问为：

http://localhost:8080/struts2/control/employee/operation_execute

和

http://localhost:8080/struts2/control/employee/operation_add
