Maven Web 应用
本章节我们将学习如何使用版本控制系统 Maven 来管理一个基于 web 的项目，如何创建、构建、部署已经运行一个 web 应用。
创建 Web 应用
我们可以使用 maven-archetype-webapp 插件来创建一个简单的 Java web 应用。
打开命令控制台，进入到 C:\MVN 文件夹，然后执行以下的 mvn 命令：

C:\MVN>mvn archetype:generate -DgroupId=com.companyname.automobile -DartifactId=trucks -DarchetypeArtifactId=maven-archetype-webapp-DinteractiveMode=false

执行完后 Maven 将开始处理，并且创建完整的于Java Web 项目的目录结构。

[INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'archetype'. [INFO] ------------------------------------------------------------------- [INFO] Building Maven Default Project [INFO]task-segment: [archetype:generate] (aggregator-style) [INFO] ------------------------------------------------------------------- [INFO] Preparing archetype:generate [INFO] No goals needed for project - skipping [INFO] [archetype:generate {execution: default-cli}] [INFO] Generating project in Batch mode [INFO] -------------------------------------------------------------------- [INFO] Using following parameters for creating project from Old (1.x) Archetype: maven-archetype-webapp:1.0 [INFO] -------------------------------------------------------------------- [INFO] Parameter: groupId, Value: com.companyname.automobile [INFO] Parameter: packageName, Value: com.companyname.automobile [INFO] Parameter: package, Value: com.companyname.automobile [INFO] Parameter: artifactId, Value: trucks [INFO] Parameter: basedir, Value: C:\MVN [INFO] Parameter: version, Value: 1.0-SNAPSHOT [INFO] project created from Old (1.x) Archetype in dir: C:\MVN\trucks [INFO] ------------------------------------------------------------------- [INFO] BUILD SUCCESSFUL [INFO] ------------------------------------------------------------------- [INFO] Total time: 16 seconds [INFO] Finished at: Tue Jul 17 11:00:00 IST 2012 [INFO] Final Memory: 20M/89M [INFO] -------------------------------------------------------------------

执行完后，我们可以在 C:/MVN 文件夹下看到 trucks 项目，查看项目的目录结构：
Maven 目录结构是标准的，各个目录作用如下表所示:

pom.xml 文件代码如下：

4.0.0 com.companyname.automobile truckswar 1.0-SNAPSHOT trucks Maven Webapp http://maven.apache.org junit junit 3.8.1 test trucks

接下来我们打开 C:\ > MVN > trucks > src > main > webapp > 文件夹，可以看到一个已经创建好的 index.jsp 文件，代码如下：

Hello World!

构建 Web 应用
打开命令控制台，进入 C:\MVN\trucks 目录，然后执行下面的以下 mvn 命令：C:\MVN\trucks>mvn clean package
Maven 将开始构建项目:

部署 Web 应用
打开 C:\ < MVN < trucks < target < 文件夹，找到 trucks.war 文件，并复制到你的 web 服务器的 web 应用目录，然后重启 web 服务器。
测试 Web 应用
访问以下 URL 运行 web 应用：
http://:/trucks/index.jsp
验证结果：
