Maven3路程（四）用Maven创建Struts2项目

2015-05-18 00:00 453 查看
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
