E-Commerce Application

This application is multimodule app is built with Java, Spring Boot and it is built with up-to-date technologies such as, CI (github actions), JWT, Spring Security, Server-Sent-Events (SSE), Docker container etc.

Overview

In this project people can register as a user by default. There are 4 roles (USER, VENDOR, ADMIN, SUPER_ADMIN) which a user could have many. More than one role can be belong to a user. For instance, there is a user with ADMIN, USER, VENDOR role or with ADMIN and USER role.

Note

In every push to this project automatically build and extract jar then it deploys spring-boot-container into my private docker repository. Only pulling this container and setting up proper configuration you can easliy use this app, send requests. This defined in ci.yml.

Role details:

• ROLE_USER: Every user has user role by default. Users only can buy products.
• ROLE_VENDOR: Every vendor can open shop/s with products. Between vendor and shop there is OneToMany relationship, there is ManyToMany relationship between products and shop. Vendors can sell products.
• ROLE_ADMIN: Every admin can manage users which has more prievelige than the others except SUPER_ADMIN. They can give role to users and can delete/deactivate users, shops, products.
• ROLE_SUPER_ADMIN: The specific user who is only can be managed with db (manually). This can give all roles to users.

Notification, Adding roles

When user enters into app, he should automatically subscribe user-notification events that informs whether role request accept or not. When admin enters into app, he should automatically subscribe vendor-request-notification that he can accept or reject request and then messages sent to users.

Important

For reading messages there are methods that changes status of notification. You must send http request explicitly.

Server-Sent-Events logic, real-time notification delivery (even offline)

Whenever user subscribe events, if there are unread messages it contains in response body. If user is active and offline, we store notifications in db when user login we send it via SSE.
