Syllabus

Spring Fundamentals

This module provides a comprehensive introduction to the core concepts of the Spring Framework, focusing on Spring Beans, a fundamental building block of Spring applications. It covers the creation, configuration, and management of Spring Beans, along with their various scopes, inheritance, and lifecycle. By the end of this module, learners will have a solid understanding of how to create, manage, and customize Spring Beans effectively in a real-world application context. They will also learn advanced topics such as Bean inheritance, Bean scopes, and the complete lifecycle management of Beans using annotations and configurations, preparing them to build flexible and maintainable Spring-based applications.

Dependency Injection

This module delves into the concept of Dependency Injection (DI), a core feature of the Spring Framework that enables the creation of flexible, maintainable, and loosely coupled applications. It begins by exploring the necessity of DI, demonstrating how it facilitates better code management and modular design. The module further explains different types of Dependency Injection methods, such as Constructor and Setter Injection, and illustrates how to handle various complex dependencies like collections and custom objects. By the end of this module, learners will be able to effectively implement DI in their Spring applications, configure it using different techniques, and manage complex dependencies to build scalable and modular software solutions.

Annotation with Autowiring

This module focuses on using annotations to simplify Dependency Injection and autowiring in Spring applications. It introduces the concept of autowiring, explaining its need and various methods, such as by type, name, and constructor. The module also explores key annotations like @Autowired, @Resource, and @Inject, providing a comparative analysis and best practices for their use. Additionally, it delves into the @Required annotation, demonstrating its significance in enforcing mandatory properties during bean configuration. By the end of this module, learners will be able to utilize autowiring annotations effectively, understand their differences, and apply them appropriately to enhance the maintainability and scalability of Spring applications.

Spring AOP

This module introduces learners to Aspect-Oriented Programming (AOP) in Spring, a powerful technique used to modularize cross-cutting concerns such as logging, security, and transaction management. It begins with the fundamental concepts of AOP, including aspects, advice, join points, and pointcuts, and highlights the benefits and real-world applications of using AOP in Spring. The module then provides a deep dive into pointcut expressions, explaining their syntax and use cases. Finally, it covers the implementation of Spring AOP using AspectJ with XML configuration, guiding learners through setting up aspects and advices for various operations. By the end of this module, learners will be able to apply AOP techniques to create clean, maintainable, and modular Spring applications by separating cross-cutting concerns effectively.
