在eclipse中新建项目StrutsDemo1【struts的配置见】struts开发<在eclipse中配置struts. 一>

详细文件夹结构例如以下

struts开发&lt;struts中的action详细配置. 二&gt;

第一种配置方法

新建UserAction

package fzl.user.struts.demo;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

public String list(){

	System.out.println("list");

	return "success";

}

public String input(){

	System.out.println("input");

	return "success";

}	

public String add(){

	System.out.println("add");

return "success";

}}

在struts重配置

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

	<package name="default" namespace="/" extends="struts-default">

		<!-- 第一种,配置多个action -->

		<action name="add" class="fzl.user.struts.demo.UserAction" method="add">

		<result name="success">/WEB-INF/User/add.jsp</result>

		</action>

		<action name="input" class="fzl.user.struts.demo.UserAction" method="input">

		<result name="success">/WEB-INF/User/input.jsp</result>

		</action>

	<action name="list" class="fzl.user.struts.demo.UserAction" method="list">

		<result name="success">/WEB-INF/User/list.jsp</result>

		</action>

	</package>

</struts>

新建input.jsp 、list.jsp、add.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

<h1>------------------input-----------------</h1>

</body>

</html>
<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

<h1>------------------add-----------------</h1>

</body>

</html>
<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

<h1>------------------list-----------------</h1>

</body>

</html>

执行tomcat，在浏览器输入http://localhost:9000/strustDemo1/input

同理输入响应的文件夹就会得到对应的页面输出

另外一种配置方法

其它的不用修改，直接修改UserAction和struts.xml就可以

package fzl.user.struts.demo;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

public String list(){

	System.out.println("list");

	return "list";

}

public String input(){

	System.out.println("input");

	return "input";

}	

public String add(){

	System.out.println("add");

return "add";

}}
<action name="User" class="fzl.struts.demo.UserAction">

    <result name="add">/WEB-INF/User/list.jsp</result>

    <result name="input">/WEB-INF/User/input.jsp</result>

    <result name="list">/WEB-INF/User/add.jsp</result>

    </action>

执行时输入http://localhost:9000/StrutsDemo2/User!add 就可以得到对应的页面

第三种方法

package fzl.user.struts.demo;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

public String list(){

	System.out.println("list");

	return "success";

}

public String input(){

	System.out.println("input");

	return "success";

}	

public String add(){

	System.out.println("add");

return "success";

}}

通过通配符配置，通配符不来了解的自行百度

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

	<package name="default" namespace="/" extends="struts-default">

	 <action name="*_*" class="fzl.user.struts.demo.{1}Action"

			method="{2}">

			<result>/WEB-INF/{1}/{2}.jsp</result>

		</action> 

	</package>

</struts>

action的配置方法大概就这三种，后两种在开发中用的比較多
