Project: ReactiveSpringApp

Description

This is a Spring Boot 🌱 project designed to work with reactive web applications ♻️ and supports two databases: PostgreSQL 🐘 and Cassandra 🗄️. Users can configure the application to use either database as per their requirements. The project leverages modern Java ☕ features and frameworks like WebFlux ♻️ and R2DBC for reactive programming ⚡.

---

Features

• ⚡ Reactive programming with WebFlux ♻️.
• 📊 Support for PostgreSQL 🐘 and Cassandra 🗄️ databases.
• 🛠️ Built with Java 21 ☕.
• 🖥️ Ready for native image compilation using GraalVM.

---

Prerequisites

Before running the application, ensure you have the following installed:

• Java Development Kit (JDK) 21 ☕ or higher.
• PostgreSQL database 🐘 (if using PostgreSQL).
• Cassandra database 🗄️ (if using Cassandra).
• Docker (optional, for containerized database setup).
• Maven or Gradle for dependency management.

Clone the Repository

git clone https://github.com/Jaxongirshoh/reactivespringapp.git
cd reactivespringapp

Build the Project

gradle build

Database Configuration

PostgreSQL Configuration 🐘

1. Update the application.yml or application.properties file:

spring:
  r2dbc:
    url: r2dbc:postgresql://localhost:5432/your_database
    username: your_username
    password: your_password

2. Ensure the PostgreSQL database is running. You can use Docker to set up a PostgreSQL instance:

docker run --name postgres-db -e POSTGRES_USER=your_username -e POSTGRES_PASSWORD=your_password -e POSTGRES_DB=your_database -p 5432:5432 -d postgres

Cassandra Configuration 🗄️

1. Update the application.yml or application.properties file:

spring:
  data:
    cassandra:
      contact-points: localhost
      port: 9042
      keyspace-name: your_keyspace
      username: your_username
      password: your_password

2. Ensure the Cassandra database is running. You can use Docker to set up a Cassandra instance:

docker run --name cassandra-db -e CASSANDRA_KEYSPACE=your_keyspace -p 9042:9042 -d cassandra
