一、搭建第一个struts项目
1.1新建一个web项目
1.2导入所需jar包
1.3web.xml中配置struts核心过滤器
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>1_struts_hello</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 配置struts核心过滤器(过滤请求) --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
1.4写action处理类
package edu.aeon.struts2.action; import com.opensymphony.xwork2.ActionSupport; /** * [说明]:action处理类 * @author aeon * */ public class HelloAction extends ActionSupport { public String helloAc(){ System.out.println("hello,struts2!"); return SUCCESS; } }
1.5在struts.xml核心配置文件中配置请求映射(将一个请求映射到一个action处理类)
<?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> <!-- struts基于包管理 --> <package name="hello" namespace="/" extends="struts-default"> <action name="helloAction" class="edu.aeon.struts2.action.HelloAction"> <result name="success">/hello.jsp</result> </action> </package> </struts>
1.6编写显示页面hello.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>hello,struts</title> </head> <body> hello,struts!!! </body> </html>
