struts2中Action基础

第一种Action直接写execute方法

package com.lbx.action;

public class IndexAction1 {
	
	public String execute() {
		return "success";
	}
	
}

 

第二种Action实现Action接口

package com.lbx.action;

import com.opensymphony.xwork2.Action;

public class IndexAction2 implements Action{

	public String execute() throws Exception {
		// TODO Auto-generated method stub
		return SUCCESS;
	}

}

 


第三种继承ActionSupport类，而ActionSupport类已经实现了Action的接口

package com.lbx.action;

import com.opensymphony.xwork2.ActionSupport;

/**
 * 
 * @author Administrator
 * 一般用这种
 *
 */

public class IndexAction3 extends ActionSupport{

	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		return SUCCESS;
	}
	
}

 

接下来就是配置struts.xml文件就可以了

<?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>
<constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant>
    <package name="login" namespace="/" extends="struts-default">
    	<action name="index" class="com.lbx.action.IndexAction3">
    		<result name="success">
    			/ActionIntroduction.jsp
    		</result>
    	</action>
    </package>
    
</struts>
