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>2.3.24</version>
- </dependency>
- </dependencies>
- <build>
- <finalName>maven-struts-demo</finalName>
- </build>
- </project>
复制代码
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.action">去登录界面</a>
- </body>
- </html>
复制代码
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.action" method="post">
- name:<input type="text" name="name" />
- password<input type="password" name="password" />
- <input type="submit" value="登录" />
- </form>
- </body>
- </html>
复制代码
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.action" 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>
复制代码
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>*.action</url-pattern>
- </filter-mapping>
- </web-app>
复制代码
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=UserLoginAction" method="user_login">
- <result name="success">/login.jsp</result>
- </action>
- <action name="login_go" class="UserLoginAction" method="login">
- <result name="success">/welcome.jsp</result>
- </action>
- </package>
- </struts>
复制代码6.建立 src/main/java目录中建立UserLoginAction.java
- public class UserLoginAction {
- private String name;
- private String password;
-
- public String user_login() {
- return "success";
- }
-
- public String login(){
- return "success";
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPassword() {
- return password;
- }
- public void setPassword(String password) {
- this.password = password;
- }
- }
复制代码
