Spring Boot Lecture Notes

Introduction

• Speaker: Alias My Name is the Wind Ready
• Topic: Spring Boot

Background on Spring Framework

Early 2000s Context

• Java EE was used for enterprise projects
• Key Feature: EJB (Enterprise JavaBeans)
  • Provided features like messaging and entity lookup
  • Challenging to manage entities as they were heavy
• Solution: Concept of POJOs (Plain Old Java Objects)
  • Achieved the same features with lighter objects
  • Included in Spring Framework

Key Features of Spring Framework

• POJOs Support: Reduced complexity
• Dependency Injection: Simplifies object creation and management
• AOP (Aspect-Oriented Programming): Adds additional functionality
• Integrates with other frameworks (Hibernate, Struts)
• Suitable for various business purposes

Limitations of Spring Framework

• Heavy use of external Java files
• Complex configuration, especially for enterprise applications
  • Developers prefer to focus on coding, not configuration

Introduction to Spring Boot

• Not a replacement but a complement to Spring Framework
• Aims to minimize setup and configuration
• Main Idea: Provide production-ready applications
  • Minimal initial configuration
  • Focus on coding rather than setup

Features of Spring Boot

• Dependency Management: Handles necessary jar files
• Auto Configuration: Preconfigures the application
• Embedded Server: Includes a server within the jar file
  • Usually Tomcat
  • Simplifies deployment and running

Advantages in Modern Development

• Supports microservices architecture
• Easier to set up and run web applications
  • No need for separate web server (Tomcat is embedded)

Starter Projects

• Predefined templates for various types of projects
  • Examples: spring-boot-starter-web, spring-boot-starter-jdbc
• Provides a ready-to-use project setup

Auto Configuration

• Automatically configures most parts of the application
• Reduces the need for manual setup

Configuration Management

• Application.properties: Handles custom configurations
  • Easier and more straightforward than XML files

Practical Implementation

• Links to practical videos mentioned (found in the description)
• Overview of Spring Boot project creation

Conclusion

• Spring Boot enhances productivity by reducing setup time
• Focus on coding and convention over configuration
