Middleware Application

A simple Middleware Application with Java and Spring Boot.

High Level Design

Installation

It's a Spring Boot and Java application with a very little functionality. Here are the commands you need to run one by one-

git clone https://github.com/CodeMechanix/Digital-Backend.git
cd Digital-Backend
mvn clean
mvn spring-boot:run

Then you need to put your database credentials in the application-dev.yml file. I used PostgreSQL in this project.

Then you can visit the base url in this url- http://localhost:7007/.

Docker Image Build

# Build the Docker image using the following command:

docker build -t middleware .

# Once the image is built, run a container using the following command:

docker run -p 7007:7007 middleware

This will start a container and map port 7007 on the host to port 7007 in the container, making the Spring Boot application accessible on http://localhost:7007.

Uses

This application can be used both in logged in or logged out state. But for using the full potential, you should logged in.

This project has the following features-

PreAuthorize: @PreAuthorize is an annotation in Spring Security that allows you to specify authorization rules for your application's endpoints. It can be used to define access control for methods in a Spring-based application.
Swagger: Swagger is a popular open-source framework for building and documenting RESTful APIs. In a Spring Boot application, you can use the Swagger library to generate documentation for your API, which can be easily accessible and understandable by both developers and end-users.
API Security: API Security purpose I used Authentication based API Data communication.
Logging: Logging purpose, I use Database layer Request log and besides this file based log management system.
Unit Testing: API coverage Unit Testing.
Loosely couple design the Middleware Application.

Database

MW_USER : Manage all Authenticate User Information.

MW_HISTORY : Logging All User Request details with Time. Beside this manage file base log.

MW_COURIER : Courier-Rate Details Information. Load data through Scheduler and have manual process for sync realtime data. Courier Service easily active/Inactive as per demand.

Using PostgreSQL DB?

# Data source 
spring.datasource.databaseName=MIDDLEWAREDB
spring.datasource.serverName=localhost
spring.datasource.url=jdbc:oracle:thin:@localhost:1525/MIDDLEWAREDB
spring.datasource.driverClassName=oracle.jdbc.OracleDriver
spring.datasource.username=middleware
spring.datasource.password=middleware123
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

Is this configuration for PostgreSQL DB?
