1. Spring Core Concepts

Overview of Spring Framework: A comprehensive framework for building Java applications.
IoC (Inversion of Control) Container: Manages the lifecycle and configuration of application objects.
Dependency Injection (DI): Injects dependencies into Spring beans to promote loose coupling.
Spring Bean Lifecycle: Stages of a bean’s lifecycle including instantiation, initialization, and destruction.
Key Spring Annotations:
- @Component, @Service, @Repository, @Controller
- @Autowired for dependency injection.
- @Configuration, @Bean for configuration.
- @Qualifier to specify which bean to use.
Spring Boot and Auto-Configuration: Simplifies Spring development by providing auto-configuration and an embedded server.

RESTful Web Services in Spring Boot: Build REST APIs with Spring Boot annotations.
Controller Layer: Use @RestController to handle HTTP requests.
HTTP Methods: Implement `GET`, `POST`, `PUT`, `DELETE` methods.
Request and Response Handling: Use @RequestBody, @PathVariable, @RequestParam.
Building RESTful APIs: Create endpoints, handle data using DTOs.
Validation and Error Handling: Implement validation with @Valid, handle errors with @ControllerAdvice.
HATEOAS: Implement hypermedia-driven REST API.

Spring Data JPA: Simplifies database access with repositories.
Entity Class and Repositories: Define entities with @Entity and use repository interfaces like CrudRepository.
Hibernate ORM: Maps Java objects to database tables.
Database Migrations: Use tools like Flyway or Liquibase for schema versioning and management.
Connecting to Databases: Configure database connections in application.properties.
SQL vs NoSQL: Work with relational databases and NoSQL databases like MongoDB.

Spring Security Basics: Provides authentication and authorization features.
Authentication and Authorization: Secure endpoints using user roles and permissions.
JWT Authentication: Implement JSON Web Token for stateless authentication.
OAuth2 Integration: Integrate third-party login services using OAuth2.
CSRF Protection: Protect against Cross-Site Request Forgery attacks.

Maven/Gradle for Building: Use Maven or Gradle to compile and package the application.
Creating Executable JAR or WAR: Package the application as a JAR or WAR file.
Local and Cloud Deployment: Deploy on local servers or cloud platforms like AWS, Heroku.
Docker Containerization: Create Docker images for your Spring Boot application.
CI/CD Pipeline Setup: Automate build, test, and deployment processes using CI/CD tools.
