In this section we will learn how to use the version control system Maven to manage a web-based project and how to create, build, and deploy an already running web application.

11.17.1. Create a Web application

We can use the maven-archetype-webapp plug-in to create a simple Java web application.

Open the command console, go to the C:MVN folder, and execute the following mvn command:

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

After execution, Maven will start processing and create a complete directory structure for the Java Web project.

After execution, we can see the trucks project under the C:/MVN folder and view the directory structure of the project:

The Maven directory structure is standard, and the functions of each directory are shown in the following table:

Folder structure

Description

Trucks

Contains the src folder and the pom.xml file.

Src/main/webapp

Contains index.jsp files and WEB-INF folders.

Src/main/webapp/WEB-INF

Include web.xml files

Src/main/resources

Contains pictures and properties resource files.

The pom.xml file code is as follows:

<projectxmlns="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

 Next, open the C:> MVN > trucks > src > main > webapp > folder, and you can see a created index.jsp file with the following code: 
 
 
 
Hello World!


 
 
  
 
  11.17.2.  Build Web application  
 
 Open the command console, change to the C:MVNtrucks directory, and execute the following mvn command: 
 
 
 
C:\MVN\trucks>mvn clean package

 
 
 
 Maven will begin to build the project:

 In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
