在eclipse中新建项目StrutsDemo1【struts的配置见】struts开发<在eclipse中配置struts. 一>
具体目录结构如下
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>
运行tomcat，在浏览器输入http://localhost:9000/strustDemo1/input
同理输入响应的目录就会得到相应的页面输出
第二种配置方法
其他的不用改动，直接改动UserAction和struts.xml即可
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>
运行时输入http://localhost:9000/StrutsDemo2/User!add 即可得到相应的页面
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较多
