Agenda of the Course1:31

Introduction to Spring Boot12:58
What is Inversion of Control [IOC Container]1:06
Learn how the IOC container manages Spring beans, dependency injection, and the lifecycle from instantiation to destruction, including reading configuration from XML files, Java config, or annotations.
Creating Spring Boot First Application8:08
Create a Spring Boot first application using Spring Initializr or an integrated development environment, configure Java 17 and Spring Web, and expose a rest endpoint at /welcome.
Spring Boot Internal Execution Flow7:03
Spring Boot Runners8:05
[NEW] Monitoring & Managing Spring Boot Applications with Actuator5:52

@Component, @Repository, @Service and @Controller7:39
What is Dependency Injection ?1:27
Explain dependency injection as a design pattern that injects dependent objects into target classes to promote loose coupling, focusing on Spring's setter, constructor, and field injection.
@Autowired Annotation5:03
Learn how the @Autowired annotation injects dependencies at runtime using setter, constructor, and field injection in a sample product service and controller.
@Value Annotation4:18
Demonstrates the @Value annotation to assign default values and read data from application.properties, showing how to inject studentId and studentName into a Spring bean.
@Qualifier and @Primary Annotations7:58
@Bean and @Configuration Annotations4:41

Stereo-Type Annotations7:39
@RequestMapping Annotation5:36
@RestController Annotation3:17
@GetMapping Annotation5:50
@RequestParam Annotation3:36
@PathVariable Annotation3:13
@PostMapping, @RequestBody Annotations4:13
@PutMapping Annotation3:50

Autowired Annotation
Qualifier Annotation
Primary Annotation
SpringBootApplication
Bean and Configuration Annotations
Controller, Service, and Repository
Value Annotation
Controller and ResponseBody Annotations

What is Spring Framework ?

Spring Framework is a popular open-source Java-based application framework that provides a comprehensive infrastructure for developing Java applications. It was initially created to simplify the development of enterprise applications, but it has since expanded to become a general-purpose framework for developing any kind of Java application.

What is Spring Boot ?

Spring Boot is basically an extension of the Spring framework which eliminates the boilerplate configurations required for setting up a Spring application.

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily. The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration again and again.

Tools and technologies used:

Spring Boot
Java
STS IDE
Maven
Postman Client
