Maven Web應用
本教程將教你如何管理使用Maven版本控制系統管理一個基於Web項目。在這裏，將學習如何創建/構建/部署和運行Web應用程序：
創建Web應用程序
要創建一個簡單的java web應用程序，我們將使用Maven的原型 - web應用插件。因此，讓我們打開命令控制檯，進入到C： MVN目錄並執行以下命令mvn命令。
C:MVN>mvn archetype:generate
-DgroupId=com.companyname.automobile
-DartifactId=trucks
-DarchetypeArtifactId=maven-archetype-webapp
-DinteractiveMode=false
Maven會開始處理，並建立完整的基於Web的Java應用程序項目結構。

現在去到C:/ MVN目錄。您將看到創建了一個名爲trucks （如artifactId指定）一個java應用程序項目。
Maven使用標準的目錄結構。用上面的例子中，我們可以瞭解到以下關鍵概念
文件夾結構
描述
trucks
contains src folder and pom.xml
src/main/webapp
contains index.jsp and WEB-INF folder.
src/main/webapp/WEB-INF
contains web.xml
src/main/resources
it contains images/properties files .
POM.xml
<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"\>
Maven還創建了一個示例JSP源文件
打開 C: > MVN > trucks > src > main > webapp > 文件夾，你會看到index.jsp。
Hello World!
構建Web應用程序
讓我們打開命令控制檯，進入到C:MVN rucks目錄並執行以下命令mvn命令。
C:MVN rucks>mvn clean package
Maven將開始建設該項目。

部署Web應用程序
現在複製創建的trucks.war 到**C: > MVN > trucks > target >**文件夾到web服務器的webapp目錄下，然後重新啓動Web服務器。
測試Web應用程序
使用URL運行Web應用程序 : http://
驗證輸出。
