Comparison of Topics: Spring vs Spring Boot

1. Introduction and Overview

Spring Framework:

  • Introduction to Spring: Basics of the Spring Framework, understanding the need for Spring in enterprise applications.
  • Core Concepts of Spring: Inversion of Control (IoC), Dependency Injection (DI), and Aspect-Oriented Programming (AOP).
  • History and Evolution of Spring: From Spring 1.x to Spring 5.x and beyond.
  •  

Spring Boot:

  • Introduction to Spring Boot: Understanding how Spring Boot simplifies the Spring development process.
  • Why Spring Boot: Benefits like convention over configuration, embedded servers, and rapid application development.
  • Spring Boot vs. Spring Framework: When to use Spring Boot over traditional Spring.
  •  

2. Setup and Configuration

Spring Framework:

  • Setting up Spring Project: Manual setup using XML and Java Config.
  • Spring Beans and Configuration: XML-based and Annotation-based configuration.
  • Dependency Management: Using Maven or Gradle to handle dependencies.

Spring Boot:

  • Setting up Spring Boot Project: Using Spring Initializr (start.spring.io) to create a Spring Boot project.
  • Auto-Configuration: How Spring Boot configures your application based on dependencies.
  • Spring Boot Maven/Gradle Plugin: Automatic dependency management and project setup using Spring Boot’s conventions.

 

3. Core Components

Spring Framework:

  • Spring IoC Container: Detailed explanation of Bean Factory, ApplicationContext, and Bean scopes.
  • Spring AOP (Aspect-Oriented Programming): Introduction to AOP concepts and using Spring AOP for cross-cutting concerns.
  • Spring JDBC and ORM: Using Spring for database interaction (JDBC, JPA, Hibernate).
  • Spring MVC: The Model-View-Controller architecture and creating web applications with Spring MVC.

Spring Boot:

  • Spring Boot Auto Configuration: How Spring Boot automatically configures your app’s settings.
  • Embedded Servers: Working with embedded Tomcat, Jetty, or Undertow.
  • Spring Boot Profiles: Managing different environments (dev, prod) using profiles.
  • Spring Boot Starter Projects: Pre-configured templates for building web, data, and other types of applications.
  • Actuator: Monitoring and managing your Spring Boot application in production (health checks, metrics, etc.).

 

4. Web Development

Spring Framework:

  • Spring MVC: Building RESTful web services, handling HTTP requests, and using controllers and views.
  • Spring Security: Securing web applications using Spring Security.
  • Form Handling and Validation: Binding form data and validation with JSR-303/JSR-380 (Bean Validation).

Spring Boot:

  • Spring Boot for Web Development: Setting up REST APIs using Spring Boot.
  • Embedded Tomcat/Jetty: Running web applications with embedded servers.
  • Spring Boot Security: Simplified configuration for securing REST APIs and web apps.
  • Spring Boot REST Services: Creating RESTful services with minimal configuration.
 
 

5. Data Access and Persistence

Spring Framework:

  • Spring JDBC: Managing database connections and transactions using JDBC.
  • Spring ORM: Integrating with ORM frameworks like Hibernate.
  • Spring Data JPA: Simplifying data access through the use of Spring Data JPA and repositories.

Spring Boot:

  • Spring Boot Data Access: Using Spring Boot with Spring Data JPA, Spring Data MongoDB, and other Spring Data modules.
  • Embedded Databases: Using embedded databases like H2 for development and testing.
  • Spring Boot Data Integration: Simplifying database connection setup and management with Spring Boot’s default configurations.

 

6. Microservices Architecture

Spring Framework:

  • Spring Cloud: Building microservices using Spring Cloud for service discovery, configuration management, and load balancing.
  • Spring Integration: Integrating microservices and external systems.
  • Spring Messaging: Using JMS, AMQP, and Kafka with Spring for messaging-based communication.

Spring Boot:

  • Microservices with Spring Boot: Creating lightweight microservices using Spring Boot.
  • Spring Cloud with Spring Boot: Using Spring Boot for building scalable, fault-tolerant microservices in a distributed system.
  • Spring Boot with Docker: Containerizing Spring Boot applications with Docker for easy deployment and scaling.

 

7. Testing

Spring Framework:

  • Unit Testing with Spring: Using JUnit, Mockito, and Spring TestContext Framework for testing Spring beans.
  • Integration Testing: Testing the interaction between components and database layers.

Spring Boot:

  • Spring Boot Testing: Simplified testing with Spring Boot’s built-in support for unit tests, integration tests, and end-to-end tests.
  • Testing REST APIs: Using Spring Boot’s testing support for testing RESTful web services with tools like MockMvc.

 

8. Advanced Topics

Spring Framework:

  • Spring Batch: Handling large volumes of data and batch processing.
  • Spring Integration: Integrating with external systems and managing complex workflows.
  • Spring WebFlux: Asynchronous programming with Spring WebFlux for building reactive applications.

Spring Boot:

  • Spring Boot Customization: Customizing auto-configuration and writing custom Spring Boot starters.
  • Spring Boot with Cloud Providers: Deploying Spring Boot applications to cloud services like AWS, Azure, or Google Cloud.
  • Spring Boot and Kubernetes: Deploying and managing Spring Boot applications in a Kubernetes environment.
 
 

9. Deployment and Monitoring

Spring Framework:

  • Deploying Spring Applications: Deploying Spring applications to external containers like Tomcat or JBoss.
  • Application Monitoring: Using tools like Spring Insight for application performance monitoring.

Spring Boot:

  • Deploying Spring Boot Applications: Deploying applications as standalone JARs or WARs (to be deployed on external servers or as cloud-native applications).
  • Monitoring with Spring Boot Actuator: Using Spring Boot’s built-in actuator for monitoring, health checks, and metrics.
 
 

10. Conclusion and Best Practices

Spring Framework:

  • Best Practices in Spring: Design patterns, coding best practices, and performance optimization in Spring applications.
  • Security Considerations: Best practices for securing Spring applications.

Spring Boot:

  • Spring Boot Best Practices: Configuring Spring Boot for optimal performance and scalability.
  • Optimizing Spring Boot Applications: Techniques for improving Spring Boot startup times, memory usage, and performance.
 

Summary of Key Differences:

  • Spring Framework focuses on a comprehensive approach to building Java-based applications with a wide range of features, including AOP, IoC, MVC, and more. It requires more configuration and setup, particularly in terms of XML or annotation-based configurations.

  • Spring Boot, on the other hand, is designed for rapid development with less configuration. It eliminates the need for complex XML-based configuration and provides default setups for most common features (e.g., embedded servers, data access, etc.), making it ideal for microservices and cloud-native applications.
