用Maven创建第一个web项目

一.创建项目

1.Eclipse中用Maven创建项目

上图中Next

 

2.继续Next

 

3.选maven-archetype-webapp后，next

 

4.填写相应的信息，Packaged是默认创建一个包，不写也可以

 

5.创建好项目后，目录如下：

至此，项目已经创建完毕，下边可是配置。

二.项目配置

1.添加Source Folder

Maven规定，必须创建以下几个Source Folder

src/main/resources

src/main/java

src/test/resources

src/test/java

添加以上的Source Folder

创建好后的目录如下：

2.配置Build Path

 

3.设定4个文件夹的输出Output folder，双击修改

分别修改输出路径为

src/main/resources　　对应　　target/classes

src/main/java　　对应　　target/classes

src/test/resources　　对应　　target/test-classes

src/test/java　　对应　　target/test-classes

4.修改后如下图

 

5.设定Libraries

 

6.配置完Build Path后目录如下：

7.将项目转换成Dynamic Web Project

在项目上右键Properties

在左侧选择 Project Facets,单击右侧的 ”Convert faceted from “

 

8.修改Java为你当前项目的JDK，并添加Dynamic Web Module ，最后单击”Further Configuration available“ 链接：

 

9.修改Content directory 为 src/main/webapp ,单击OK:

 

10.设置完Content directory，ok后再次点击前一界面ok，完成转换成Dynamic Web Project项目

 

11.设置部署程序集(Web Deployment Assembly)

在项目上右键单击，选择Properties，在左侧选择Deployment Assembly

 

12.设置部署时的文件发布路径

　　1，我们删除test的两项，因为test是测试使用，并不需要部署。
　　2，设置将Maven的jar包发布到lib下。 
　　　　Add -> Java Build Path Entries -> Maven Dependencies -> Finish

设置完成后如图

 

ok后，web项目就创建完毕了，目录机构如图

运行后访问工程成功！

下一章将测试一个servlet

Maven3路程（三）用Maven创建第一个web项目(2)servlet演示

上一章用Maven新建了web项目成功后，本文演示在此基础上应用servlet。

1.首先修改pom.xml文件，添加servlet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-web-demo</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>maven-web-demo Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>      <!-- JUnit配置 -->    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>    <!-- 添加Servlet -->      <dependency>            <groupId>javax.servlet</groupId>            <artifactId>servlet-api</artifactId>            <version>2.5</version>            <scope>provided</scope>        </dependency>  </dependencies>  <build>    <finalName>maven-web-demo</finalName>  </build></project>

修改完保存后，项目会从Maven仓库中自动添加servlet-api-2.5.jar包的引用，如果仓库中没有，会自动下载。

引用后见图。

 

2.新建一个Servlet

在src/main/java下创建一个Servlet，ServletDemo

package com.sulei.demo;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * Servlet implementation class ServletDemo */public class ServletDemo extends HttpServlet {    private static final long serialVersionUID = 1L;           public ServletDemo() {        super();    }    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        doPost(request, response);    }    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        request.setCharacterEncoding("UTF-8");          response.setContentType("text/html;charset=utf-8");                String action = request.getParameter("action");          if("login_input".equals(action)) {              request.getRequestDispatcher("login.jsp").forward(request , response);          } else if("login".equals(action)) {              String name = request.getParameter("name");              String password = request.getParameter("password");                            System.out.println("name->" + name + ",password->" + password);        }    }}

 

3.修改Web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:javaee="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <javaee:display-name>Archetype Created Web Application</javaee:display-name>  <servlet>    <javaee:description></javaee:description>    <javaee:display-name>ServletDemo</javaee:display-name>    <servlet-name>ServletDemo</servlet-name>    <servlet-class>com.sulei.demo.ServletDemo</servlet-class>  </servlet>  <servlet-mapping>    <servlet-name>ServletDemo</servlet-name>    <url-pattern>/demo</url-pattern>  </servlet-mapping></web-app>

 

4.创建index.jsp

<%@ page language="java" 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>Insert title here</title></head><body>    <p>用Maven创建web项目，测试Servlet</p>    <a href="demo?action=login_input">登录(demo?action=login_input)</a></body></html>

 

5.创建login.jsp

<%@ page language="java" 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>Insert title here</title></head><body>    <form action="demo?action=login" method="post">          Name:<input type="text" name="name" />          Password:<input type="password" name="password" />                        <input type="submit" value="登录" />      </form>  </body></html>

 

OK，可以测试一下

 

Maven3路程（四）用Maven创建Struts2项目

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
