Payment Management System

Payment-Management-System

---

The goal of the project is to create a complete payment system with all the basic functionality.
I deployed the application on the hosting.
Go to this address: https://payment-management-system.herokuapp.com/

Used tools and patterns for project implementation

Primary: MySQL 5.7, Java 8 (Core + Servlets + JDBC + JSP), JSTL, Maven 3, HTML CSS, JS, jQuery v3.4, Bootstrap v4.4.
Secondary: Apache Tomcat v9.0, Apache Commons Lang v2.6, Apache Log4j v1.2, JUnit v4.13, Mockito v1.10.
*For more information on dependencies and plugins, see the pom.xml file.

When implementing business logic algorithms, I used GoF patterns (Singleton, Builder, Factory Method, Command, Strategy), as well as MVC and DAO patterns.

Initialization and launch of the project

For the correct launch and stable operation of the site (locally) you need to:

• Download and uncompress the .zip archive of this repository. I recommend cloning a project (if you know Git):
  $ git clone https://github.com/SValentyn/Payment-Management-System.git
• Specify the correct path to the JDK home folder in the IDE.
• Connect, configure and start your database server.
• Import the database dump from the /resources/sql/dump.sql file (substituting your DB name).
• Specify the correct database connection parameters in the /webapp/META-INF/context.xml file
• Uncomment the block of code needed for your purposes in the /persistence/dao/impl/QueryExecutor.java file (contains the basic methods for working with the DB).
• Run the project build command from the root folder: $ mvn clean package
• Connect and configure your web server to deploy the project locally.
• Verify that all components are configured correctly and that all services are running.
• In the browser, go to this address: http://localhost:8080/

If you know Docker, use these commands by running them from the root folder:
    $ docker build -f Dockerfile -t pms-assembly .
    $ docker run --name mysql57 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=pppp -d mysql/mysql-server:5.7
    $ docker run -d -p 8080:8080 pms-assembly
Or use this command by running it from the root folder:
    $ docker-compose up --build -V

I advise you to use the first option with manual installation and configuration.

Use Case diagrams

All options for using the system can be found in Use Case diagrams. Since there are two types of users in the system: Regular User (Client) and Administrator, the corresponding two Use Case diagrams were created. Their main difference from each other is that they have different privileges and specific capabilities.

Use Case diagram for Regular User (Client):

Use Case diagram for Administrator:
