Spring Boot Roadmap

Introduction to Spring Boot

• Spring Boot is an enhancement over the Spring framework.
• Advantages:
  • Easy configuration.
  • Starter dependencies.
  • Integrated server for deployment.
  • Production-ready features.

Setting Up Your Initial Spring Boot Project

• Creating and running the first Spring Boot project.
• Use of IDEs like IntelliJ.
• Understanding the layered architecture:
  • Controller Layer
  • Service Layer
  • Repository Layer

Build Tools: Maven and Gradle

• Build tools manage dependencies for applications.
• Maven uses pom.xml for dependency management.
• Gradle as an alternative option.

Understanding Spring Boot Annotations

• Key annotations: @SpringBootApplication, @Controller, @RestController, @RequestMapping, etc.
• Importance of knowing what each annotation does.

Dependency Injection (DI)

• Core concept in Spring for managing dependencies.
• Types of DI:
  • Field Injection
  • Setter Injection
  • Constructor Injection

Configuring Spring Boot Applications

• Using application.properties or application.yaml for configurations.
• Profile-specific configurations for different environments (test, prod, etc.).

Spring Beans and Life Cycle

• Definition: Java objects managed by Spring.
• Life cycle from creation to destruction.
• Understanding Bean scopes:
  • Singleton
  • Prototype
  • Request
  • Session

Spring Boot Data Access

• Use of Spring Data JPA for database access.
• Introduction to JPA (Java Persistence API) and ORM (Object-Relational Mapping).

Creating RESTful APIs

• Basic CRUD operations as an introduction.
• Plans for more detailed RESTful API tutorials.

Spring Boot Security

• Adding dependencies for security.
• Handling authentication and authorization.

Logging and Exception Handling

• Tools and frameworks provided by Spring Boot for logging.
• Exception handling techniques within controllers.

Caching and Interceptors

• Enabling cache management.
• Using interceptors for requests and responses.

Scheduling and Unit Testing

• Spring Boot scheduling for task automation.
• Unit testing with JUnit and Mockito for mocking dependencies.

Spring Boot Actuators

• Production-ready features for monitoring and management.
• Health checks, metrics, and more.

Deploying Spring Boot Applications

• Default Tomcat server integration.
• Options for Dockerizing applications.
• CI/CD processes with Jenkins.
• Deployment on cloud platforms like AWS, Azure, or Google Cloud.

Microservices with Spring Boot

• Introduction to microservice architecture.
• Use of Eureka Server for service registration.
• Tracing with Sleuth and visualization with Zipkin.
• API Gateway as the entry point for requests.
• Spring Cloud Config for centralized configuration management.

Conclusion

• Completion of the roadmap enables project development with Spring Boot.
• Upcoming content will cover remaining topics not yet addressed in detail.
