To run this application locally, you will need to have Java and MySQL installed on your machine.

• Clone the repository to your local machine.
• Create a new MySQL database called blogapp
• Make sure you have Java JDK above 8 on ur local machine.
• Update the application.properties file in the src/main/resources directory to include your MySQL username and password
• Run the application using your IDE or by running the command mvn spring-boot:run in the project directory
• Access the APIs using any HTTP client such as Postman or Swagger open AI.

Data flow

The application is built using the SpringBoot framework and consists of seven layers: DTO, model, controller, service, security, repository and jwt

• DTO -The DTO layer consists of classes that are used to transfer data between different layers of the application
• Controller - The controller layer handles the HTTP requests, translates the JSON parameter to object, and authenticates the request and transfer it to the business (service) layer.
• Service -The business layer handles all the business logic. It consists of service classes and uses services provided by data access layers.
• Security -We configure Spring security in this layer by creating security beans such as UserDetailsService,PasswordEncoder,SecurityFilterChain
• JWT - In this layer we configure JWT Authentication filter and create Jwt entry point.
• Repository - This layer maintains the data by accessing Mysql Database on which CRUD operations are performed.. for that we extend our interface with another interface called JpaRepository.
• Model - This layer consists basically the class level things-and this classes are stored in form of tables in given Mysql database as we annotate this class by @Entity.
