All properties of the web application are centralized in the properties file and are mapped by properties classes under the package xbc.jb.socialvg.refinv.properties:

src/main/resources/application.yml

For simplicity I'm using H2 Database Engine for in-memory database, it can be simply migrated to alternative servers like MySQL By specifying the appropriate url in the properties file.

spring:  
  datasource:  
    url: jdbc:mysql://localhost:3306/db_name
  username: db_username 
  password: db_password

hibernate:  
  ddl-auto: update # create  
database: mysql

I made some properties of the web application in the property file to decouple them from the code and to make the application easily customizable.

webapp:
pagination:
page-size: 4
path:
file-sep: /
image-folder: /Users/abbesbes/images/
profile-def-img: /Users/abbesbes/images/default_profile.png

Description:

• webapp: The root of the custom properties.
  • pagination:Properties of DB pagination.
    • page-size: The size of the page to be shown in the list / DB Page size.
  • path: Properties related to paths.
    • file-sep: File Seperator which is used for path building.
    • image-folder: The path of the folder wich contain the photos uploaded by users.
    • profile-def-img: Path to the default photo to be used as profile picture for users.

The Spring Boot Maven plugin collects all jars on the classpath and build a single executable .jar which will be running on the server.

So all we need is to build this .jar and execute it on the server.

After cloning the repository simply import the project into IntelliJ IDEA as Maven Project by selecting the file pom.xml. After all dependencies are resolved, Press the run button to build and run the web application on the localhost.

If Maven is installed so we can build and run the application as follows.

From the project's root folder which contain the file pom.xml, we run the following command:

mvn install

Now a runnable .jar is created with the path refinv-0.0.1-SNAPSHOT.jar So we can execute it as follows:

java -jar target/refinv-0.0.1-SNAPSHOT.jar

Now the application is running on localhost.

I implemented an initilizer which create random users at the start of the application.

More customizations required !

Example:

http://localhost:8080/invite?code=AXE-120260

Score += 1 / lev;

Where lev is the length of the transitive invitation.

To be implemented !
