Spring Boot Blog REST API

The project demonstrates the integration of several key technologies for building production-ready RESTful services:

• Frameworks: Spring Boot 3+, Spring Security 6+
• Security: JSON Web Token (JWT) for stateless authentication and role-based authorization (both In-memory and DB-based).
• Data Access: Spring Data JPA (Hibernate) with MySQL database, including one-to-many and many-to-many mappings.
• API Design: Implementation of CRUD operations, Pagination, Sorting, URI versioning strategies, and DTO (Data Transfer Object) patterns.
• Validation & Error Handling: Spring Boot REST API validation and centralized exception handling.
• DevOps & Deployment: Docker containerization and deployment to AWS Cloud.

To build the project, navigate to the root directory of the project and execute the build command. You can use a local Maven installation or the included Maven Wrapper (mvnw).

# If Maven is installed on your machine
mvn clean package

# If Maven is NOT installed (using the wrapper)
./mvnw clean package

Before running the application, you must manually create a MySQL database named myblog. Hibernate will automatically create the necessary tables once the application starts, but the database container must exist.

create database myblog

Once the database is created and the project is built, use the following command to start the application. Hibernate will handle the automatic creation of database tables based on the entity mappings.

mvn spring-boot:run

After the application has started and tables are created, you must manually insert the required roles into the roles table to ensure proper authorization works. Use the following SQL statement:

INSERT INTO `myblog.roles` VALUES (1,'ROLE_ADMIN'),(2,'ROLE_USER');
