⚙️ Setup Instructions

2️⃣ Configure the MySQL Database

Open:

src/main/resources/application.properties

Use this config:

spring.datasource.url=jdbc:mysql://localhost:3306/miniblog?createDatabaseIfNotExist=true spring.datasource.username=root spring.datasource.password=root

spring.jpa.hibernate.ddl-auto=update spring.jpa.show-sql=true spring.jpa.properties.hibernate.format_sql=true

MySQL will automatically create the database if it doesn't exist.

3️⃣ Build and Run the Application

Using Maven:

mvn clean install mvn spring-boot:run

Or run the main class MiniBlogApplication.java from your IDE.

4️⃣ Access the Application
