【maven学习】构建maven web项目

Maven Web应用

创建Web应用程序

要创建一个简单的java web应用程序，我们将使用Maven的原型 - web应用插件。因此，让我们打开命令控制台，进入到C： MVN目录并执行以下命令mvn命令。

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

Maven会开始处理，并建立完整的基于Web的Java应用程序项目结构。

现在去到C:/ MVN目录。您将看到创建了一个名为trucks （如artifactId指定）一个java应用程序项目。

Java web application project structure

Maven使用标准的目录结构。用上面的例子中，我们可以了解到以下关键概念

文件夹结构	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">
   <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>

Maven还创建了一个示例JSP源文件

打开 C: > MVN > trucks > src > main > webapp > 文件夹，你会看到index.jsp。

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

构建Web应用程序

让我们打开命令控制台，进入到C:MVN rucks目录并执行以下命令mvn命令。

C:MVN	rucks>mvn clean package

Maven将开始建设该项目。

部署Web应用程序

现在复制创建的trucks.war 到C: > MVN > trucks > target >文件夹到web服务器的webapp目录下，然后重新启动Web服务器。

测试Web应用程序

使用URL运行Web应用程序 : http://<server-name>:<port-number>/trucks/index.jsp

验证输出。
