Spring Tutorial

Spring is a lightweight, open-source framework for building enterprise-level Java applications. It simplifies development by providing support for dependency injection (DI), aspect-oriented programming (AOP), transaction management and integration with various frameworks.

Key Features of Spring

• POJO-Based Development: Build apps using simple Java objects without heavy EJB containers.
• Modular Design: Spring is highly modular, so you only use the parts you need without unnecessary overhead.
• Framework Integration: Works well with existing technologies such as Hibernate, Quartz, JDK timers and other view frameworks.
• Easy Testing: Its DI and POJO-based approach makes testing straightforward, allowing easy injection of mock data for test cases.
• Web MVC Framework: Provides a clean, flexible and well-structured MVC framework, often preferred over heavier alternatives like Struts.
• Centralized Exception Handling: Converts framework-specific exceptions (JDBC, Hibernate, etc.) into consistent unchecked exceptions, simplifying error handling.
• Lightweight Containers: The IoC containers are lightweight compared to EJB containers, making Spring ideal for applications that need efficiency in memory and CPU usage.

1. Basics of Spring

• Introduction
• Architecture
• Reasons to Use
• Spring Initializr
• Spring vs. Struts in Java

2. Software Setup and Configuration (STS/Eclipse/IntelliJ)

Getting started with Spring requires setting up an IDE like Spring Tool Suite (STS), Eclipse or IntelliJ IDEA.

• Download and Install
• Create and Setup Spring Boot Project
• Project with IntelliJ IDEA
• Setup in Eclipse IDE
• Run First Spring Boot Application

3. Core Spring

Core Spring focuses on Inversion of Control (IoC) and Dependency Injection (DI).

• Create a Simple Spring Application
• Inversion of Control
• BeanFactory
• ApplicationContext
• Dependency Injection
• Bean life cycle
• Bean Scope
• IoC Container
• Expression Language(SpEL)
• RowMapper vs ResultSetExtractor

4. Spring Annotations

Annotations in Spring simplify configuration and setup by providing metadata about our components.

• @Bean
• @Controller
• @Value
• @Configuration
• @ComponentScan
• @Qualifier
• @Service
• @Repository
• @Required
• @Component
• @Autowired
• @Scope
• @Required
