Quarkus Hibernate ORM PanacheEntity(class) Implementation

This guide will help you set up a Quarkus application with Hibernate ORM, creating REST endpoints and using a PostgreSQL database.

Prerequisites

  1. Docker Desktop: Install Docker Desktop to run the PostgreSQL database.
  2. IDE: Use an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.
  3. Java Version: jdk 21

Step-by-Step Guide

Step 1: Create a New Quarkus Project

  1. Go to Quarkus Code Generator.
  2. Choose the necessary dependencies for your project:
    • RESTEasy Classic
    • RESTEasy Classic Jackson
    • Quarkus Hibernate ORM Panache
    • Quarkus JDBC Postgres

Step 2: Extract and Open the Project in Your IDE

  • Extract the generated project files.
  • Open the project in your preferred IDE.

Step 3: Create REST Endpoints for CRUD Operations

Create REST endpoints for basic CRUD operations (Create, Read, Update, Delete).

Step 4: Configure application.properties

Add the following properties to src/main/resources/application.properties:

quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/my_db_movie
quarkus.datasource.username=username
quarkus.datasource.password=password
quarkus.datasource.db-kind=postgresql
quarkus.hibernate-orm.database.generation=drop-and-create.

Step 5: Build a Docker Image for POSTGRES sql.

  • Open a private command prompt for your project and run the following command
  • docker run --name my_db_movie -e POSTGRES_USER=username -e POSTGRES_PASSWORD=password -e POSTGRES_DB=my_db_movie -p 5432:5432 postgres:12.0

Step 6: Run the Application

  • Open a private command prompt for your project and run the following command
  • mvn quarkus:dev

Step 7: Test the Endpoints on POSTMAN

  • Use Postman or any other HTTP client tool to test your REST endpoints.

Step 8: (Optional) Visualize Your Database Using DBeaver

  • If you want to visualize your database schema and data, you can use DBeaver: Download and install DBeaver. Connect to your PostgreSQL database by providing the host (localhost), port (5432), username (username), password (password), and database name (my_db_movie).

Tip: Make sure you have these two installed on your PC and set the Path in Environment variables
