採用struts版本：struts-2.3.8html

一.建立一個web項目

參考前面文章，項目名：maven-struts-demo。java

二.配置pom.xml文件添加struts2依賴

<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>

保存後maven會自動下載相應的jar包。web

下載完成後查看jar包，如圖apache

三.新建JSP頁面

1.index.jsp頁面，點「去登陸界面」後，去struts.xml中找對應的anction中name=user_login_go的路徑app

<%@ 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">去登陸界面</a>
</body>
</html>

2.login.jsp頁面，輸入name和password後，去struts.xml中找對應的anction中name=login_go的路徑jsp

<%@ 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-登陸界面</title>
</head>
<body>
    <p>struts2-Demo-登陸界面</p>
    <form action="login_go" method="post">
        name:<input type="text" name="name" />
        password<input type="password" name="password" />
        <input type="submit" value="登陸" />
    </form>
</body>
</html>

3.welcome.jsp頁面，輸入name和password後，去struts.xml中找對應的anction中name=login_go的路徑maven

<%@ 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-歡迎頁面</title>
</head>
<body>
    Welcome:
    <br>
    <h1>name=<s:property value="name" /></h1>
    <h1>password=<s:property value="password" /></h1>    
    <h1>從新登陸</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.xmlpost

<!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目錄下ui

<?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>
