采用struts版本：struts-2.3.8
一.创建一个web项目
参考前面文章，项目名：maven-struts-demo。
二.配置pom.xml文件添加struts2依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.lei.demo</groupId> <artifactId>maven-struts-demo</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>maven-struts-demo Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.8</version> </dependency> </dependencies> <build> <finalName>maven-struts-demo</finalName> </build> </project>
保存后maven会自动下载相应的jar包。
下载完成后查看jar包，如图
三.新建JSP页面
1.index.jsp页面，点“去登录界面”后，去struts.xml中找对应的anction中name=user_login_go的路径
<%@ page 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> <body> <h2>Struts2-Demo</h2> <a href="user_login_go">去登录界面</a> </body> </html>
2.login.jsp页面，输入name和password后，去struts.xml中找对应的anction中name=login_go的路径
<%@ page 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>struts2-Demo-登录界面</title> </head> <body> <p>struts2-Demo-登录界面</p> <form action="login_go" method="post"> name:<input type="text" name="name" /> password<input type="password" name="password" /> <input type="submit" value="登录" /> </form> </body> </html>
3.welcome.jsp页面，输入name和password后，去struts.xml中找对应的anction中name=login_go的路径
<%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!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>Struts2-Demo-欢迎页面</title> </head> <body> Welcome: <br> <h1>name=<s:property value="name" /></h1> <h1>password=<s:property value="password" /></h1> <h1>重新登录</h1> <s:form action="login_go" namespace="/" method="post"> <s:textfield name="name" label="name"></s:textfield> <s:password name="password" label="password"></s:password> <s:submit value="Login"></s:submit> </s:form> </body> </html>
4.web.xml
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Struts2 Web Application</display-name> <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>
5.struts.xml，放在src/main/resources目录下
<?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="user" namespace="/" extends="struts-default"> <action name="user_login_go" class="com.sulei.action.UserLoginAction" method="user_login"> <result name="success">/login.jsp</result> </action> <action name="login_go" class="com.sulei.action.UserLoginAction" method="login"> <result name="success">/welcome.jsp</result> </action> </package> </struts>
目录结构：
运行效果如下
