struts2动作方法通配符

		<action name="*_*" class="com.itheima.actions.{1}" method="{2}">
			<result>/{2}.jsp</result>
		</action>
	</package>
</struts>

注意第十行,value="action,,do“ 中间两个逗号,这样配置可以在访问路径的时候省略后面的.action

 

CustomerAction.java:

package com.itheima.actions;

import com.opensymphony.xwork2.ActionSupport;

public class CustomerAction extends ActionSupport{
	public String addCustomer(){
		System.out.println("addCustomer");
		return SUCCESS;
	}
	public String delCustomer(){
		System.out.println("delCustomer");
		return SUCCESS;
	}
	public String updateCustomer(){
		System.out.println("updateCustomer");
		return SUCCESS;
	}
}
