搭建简单的struts框架
一、下载struts2所需jar包并导入到工程中(WEB-INF的lib文件夹下)

二、建立一个web工程
三、配置web.xml文件
<?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>StrutsDemo</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-list> <!-- 定义struts2 的核心控制器,用于生成ActionMapper ,拦截所有的Action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>
四、编写Action类
public class LoginAction extends ActionSupport { private static final long serialVersionUID = -6461652240745739673L; private String userName; private String password; public String execute() { if (userName.equals("zf") && password.equals("123")) { return SUCCESS; } else { return ERROR; } } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
五、建立struts.xml文件(放入Action所在包统计目录,名称必须为struts.xml)
<?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> <package name="defult" extends="struts-default"> <action name="login" class="cn.zf.action.LoginAction"> <result name="success">/jsp/success.jsp</result> <result name="error">/jsp/error.jsp</result> </action> </package> </struts>
六、编写测试页面(建一个jsp文件夹)
login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!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> <form action="login" method="post"> 用户名:<input type="text" name="userName"><br/> 密 码:<input type="password" name="password"/><br/> <input type="submit" value="提交"/> <input type="reset" value="重置"/> </form> </body> </html>
error.jsp
<%@ page language="java" contentType="text/html; charset=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=ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1>登录失败!</h1> </body> </html>
success.jsp
<%@ page language="java" contentType="text/html; charset=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=ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1>登录成功!</h1> </body> </html>
七、访问地址
