Maven Web 利用
本章节咱们将学习如何应用版本控制系统 Maven 来治理一个基于 web 的我的项目，如何创立、构建、部署曾经运行一个 web 利用。

创立 Web 利用
咱们能够应用 maven-archetype-webapp 插件来创立一个简略的 Java web 利用。

关上命令控制台，进入到 C:\MVN 文件夹，而后执行以下的 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 将开始解决，并且创立残缺的于 Java Web 我的项目的目录构造。

[INFO] -------------------------------------------------------------------

执行完后，咱们能够在 C:/MVN 文件夹下看到 trucks 我的项目，查看我的项目的目录构造：

Maven 目录构造是规范的，各个目录作用如下表所示:
pom.xml 文件代码如下：

<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.companyname.automobile</groupId>
   <artifactId>trucks</artifactId>
   <packaging>war</packaging>
   <version>1.0-SNAPSHOT</version>
   <name>trucks 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>
   </dependencies>
   <build>
      <finalName>trucks</finalName>
   </build>
</project>

接下来咱们关上 C:\ > MVN > trucks > src > main > webapp > 文件夹，能够看到一个曾经创立好的 index.jsp 文件，代码如下：

<html>
   <body>
      <h2>Hello World!</h2>
   </body>
</html>

构建 Web 利用
关上命令控制台，进入 C:\MVN\trucks 目录，而后执行上面的以下 mvn 命令：C:\MVN\trucks>mvn clean package
Maven 将开始构建我的项目:

部署 Web 利用
关上 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 利用目录，而后重启 web 服务器。

测试 Web 利用
拜访以下 URL 运行 web 利用：

http://:/trucks/index.jsp
验证后果：
