This project aims to create a web system using Spring Boot and JPA / Hibernate to manage a specific domain model. It covers everything from the initial project setup to the implementation of CRUD (Create, Read, Update, Delete) functionalities and exception handling.
- Create a Spring Boot project in Java.
- Implement the domain model.
- Structure the logical layers: config, entities, repositories, resources, and services.
- Configure a test database (H2).
- Populate the database with initial data.
- Implement CRUD operations for data manipulation.
- Handle exceptions appropriately.
- Spring Boot
- Spring Data JPA
- Hibernate
- H2 Database
The project is organized into several packages to maintain a clean and modular codebase:
- config: Contains configuration classes for Spring Boot, database configuration, and other application settings.
- entities: Holds the domain model entities representing the data structure of the application.
- repositories: Provides interfaces for data access operations, defining methods for CRUD operations and query execution.
- resources: Contains REST controllers responsible for handling HTTP requests and interacting with the service layer.
- services: Implements the business logic of the application, performing operations on the data accessed through repositories.
The project is configured to use an H2 in-memory database to facilitate development and testing. Database configurations can be found in the application-test.properties file.
CRUD (Create, Read, Update, Delete) operations are implemented to allow manipulation of the domain model data.
The project has appropriate exception handling to deal with unexpected situations during the application's execution. This ensures a better user experience and facilitates system maintenance.
