选择Artifact Id ：maven-archetype-webapp 那一项

图片描述

GroupID是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。

ArtifactID就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。一般GroupID就是填com.leafive.test这样子。

在pom中加入sturts2依赖

添加struts2依赖到的pom.xml 此处使用的是版本是3.8.1，保存文件后 maven 会自动下载依赖的相关包

图片描述

pom.xml内容：

<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.str2</groupId>
    <artifactId>struts</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>struts 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>

        <dependency>
            <groupId>javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.12.1.GA</version>
        </dependency>
    </dependencies>
    <build>
        <finalName>struts</finalName>
    </build>
</project>

3.在src/main下创建文件结构：java/action/user.java

userAction.java 内容

package com.struts.action;

public class UserAction   {
    private String name;
    private String password;
    
    
    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;
    }
    public String execute() {
        return "success";
    }
    public String user_login_go() {
        return "success";
    }
    public String login_go() {
        return "success";
    }
    public String user_login() {
        return "success";
    }
    public String login() {
        return "success";
    }
}

在resource包下创建struts2文件

<?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.struts.action.UserAction" method="user_login">
            <result name="success">/login.jsp</result>
        </action>
        <action name="login_go" class="com.struts.action.UserAction" method="login">
            <result name="success">/welcome.jsp</result>
        </action>
    </package>
</struts>

配置 src/main/webapp/WEB-INF/web.xml

web.xml 内容

<!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>Archetype Created 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>

在 src/main/webapp/WEB-INF/ 下创建一个空的文件夹 classes
在 src/main/webapp/ 创建文件inde.jsp

index.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>
<body>
    <h2>Struts2-Demo</h2>
    <a href="user_login_go">去登录界面</a>
</body>
</html>

在 src/main/webapp/创建文件 login.jsp

login.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>

在 src/main/webapp/ 创建文件 welcome.jsp

welcome.jsp

<%@ 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>
