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

<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:

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：
正文完
