Workshop Spring Boot 3 with JPA

Overview

Welcome to the Workshop Spring Boot 3 with JPA project. This comprehensive workshop is designed to equip you with the knowledge and skills required to develop robust web services using Spring Boot and JPA/Hibernate. Our primary focus is on creating a well-structured, scalable, and maintainable backend application leveraging some of the most powerful technologies in the Java ecosystem.

Goals

This workshop aims to achieve the following objectives:

1. Create a Spring Boot Java Project: Initiate and set up a new Spring Boot project using Maven, enabling rapid application development with Spring Boot's auto-configuration and starter dependencies.

2. Implement Domain Model: Design and implement the domain model, encapsulating the core business logic and entities in a structured and maintainable manner.

3. Structure Logical Layers: Establish a clear separation of concerns by organizing the codebase into logical layers:

   • Resource Layer: RESTful controllers to handle HTTP requests and responses.
   • Service Layer: Business logic and service orchestration.
   • Repository Layer: Data access and interaction with the database using JPA repositories.

4. Configure Test Database (H2): Set up and configure an H2 in-memory database for testing and development purposes, ensuring a smooth and efficient development workflow.

5. Populate the Database: Seed the database with initial data, facilitating the demonstration and testing of various CRUD operations.

6. CRUD Operations: Implement Create, Retrieve, Update, and Delete operations to interact with the domain entities, providing a complete suite of data manipulation functionalities.

7. Exception Handling: Develop a robust exception handling mechanism to gracefully manage and respond to various error scenarios, enhancing the application's resilience and user experience.

Technologies

This project leverages the following technologies to deliver a high-quality, scalable, and maintainable web service solution:

• Spring Boot: Streamlined and efficient Java-based framework for building production-ready applications quickly and easily.
• Maven: Dependency management and build automation tool to simplify project configuration and management.
• JPA/Hibernate: Object-relational mapping framework to map Java objects to database tables, providing a seamless data access layer.
• H2 Database: Lightweight in-memory database for fast and efficient testing and development.
• Apache Tomcat: Embedded servlet container to run Spring Boot applications, facilitating easy deployment and management.
• Postman: API development and testing tool to streamline the testing of RESTful web services.
• PostgreSQL: Robust, scalable, and open-source relational database management system for production deployment.
• Heroku: Cloud platform for deploying, managing, and scaling applications effortlessly.

Project Structure

The project is structured as follows to ensure clarity, maintainability, and scalability:

• src/main/java: Contains the main application code.
  • com.educandoweb.course: Base package.
    • entities: Domain entities representing the core business objects.
    • repositories: JPA repositories for data access and manipulation.
    • services: Business logic and service layer components.
    • resources: RESTful controllers to handle incoming HTTP requests.
    • config: Configuration classes, including database setup and other settings.
• src/main/resources: Configuration files and resources.
  • application.properties: Main configuration file for the Spring Boot application.
• src/test/java: Contains test classes.
• pom.xml: Maven configuration file to manage project dependencies and build process.

Getting Started

Follow these steps to set up and run the project locally:

1. Clone the Repository:

   git clone https://github.com/yourusername/workshop-springboot3-jpa.git
   cd workshop-springboot3-jpa

2. Configure the Application:

   • Ensure the application.properties file is correctly set up for your environment.
   • Configure the database settings for H2 and PostgreSQL as needed.

3. Build the Project:

   mvn clean install

4. Run the Application:

   mvn spring-boot:run

5. Access the Application:

   • The application will be available at http://localhost:8080.
   • Use Postman to test the RESTful endpoints.

Deployment

For production deployment, the application is configured to run on PostgreSQL and can be easily deployed to Heroku or any other cloud platform.
