What is a Framework? Advantages of Using a Framework9:43
Spring Framework features12:29
Dependency Injection18:40
How to import Project? Common issues when importing Projects4:22
Step by Step on how to create Spring Project from Scratch?17:30
Step by step, learn to create a Spring project from scratch, add dependencies via central repository, and load beans with a main method.
Why Bean class?1:04
A Bean is an object which is created and managed by Spring Framework
Scope of a Bean8:18
Auotwiring17:55
Learn how autowiring in Spring injects object dependencies automatically, by name or by type, using XML or annotations, with constructor or setter injection in beans like employee and salary.
Bean Configuration using Annotations6:26
Discover how to configure beans with annotations in Spring, using a @Configuration class and @Bean methods for dependencies like Employee, and let the Spring context drive dependency injection.
Bean Configurations - Lazy Loading Annotation7:47
#1. Lazy Loading can be specified through Bean xml file.
<beans>
<bean id="bid" class="com.pkg.Abcd" lazy-init="true"/>
<beans>
#2. As seen in video Scope can be specified using @Scope Annotation, for eg. @Scope("prototype")
#3. @Lazy Annotation can be used along with @Component, @Service annotations. @COmponent, @Service we will be exploring in next Lectures.
Bean Scope and LifeCycle(Annotations)5:58
Explore bean scope and life cycle in annotation-based Spring configuration, comparing singleton and prototype scopes and illustrating init and destroy methods in the bean lifecycle.
ComponentScan & Component Annotations4:19
Explore component scanning in Spring by using @Component and AnnotationConfigApplicationContext to auto-register beans, replacing XML configuration, and troubleshoot when no qualifying bean is found.
AOP - Aspect Oriented Programming46:09
Learn how aspect oriented programming in spring modularizes crosscutting concerns like logging and transaction management, using aspects, advice, join points, pointcuts, and weaving with proxies.

Spring Boot REST API49:56
Learn how springboard enables auto configuration, starter packages, and embedded tomcat to accelerate rest api development; build a hello world app and a customer CRUD controller.
Spring Boot @SpringBootApplication with componentScan to add packages12:08
How to add Dev Tools? Purpose of Dev Tools6:14
Exception Handling in Spring Boot REST API17:17
Exception Handling in Spring Boot REST API - 218:02
Learn to implement a custom error object in spring boot rest api that includes date and time, occurrence details, and temporary or permanent status for richer exceptions.

Spring Boot JPA, Data39:08
Spring Boot JPA, One to One Entity Relation9:33
Spring Boot JPA, One to Many Entity Relation26:40
Explore spring boot jpa one-to-many and many-to-one relationships between user and actors, including join columns, lazy loading, and repository usage to create and retrieve related data.
Spring Boot JPA, Many to Many Entity Relation11:30
Explore many-to-many relationships in Spring Boot JPA, using a join table to map users and addresses, and configure cascade behavior across one-to-many and many-to-one associations.

Spring Boot JPA - Entity class fields Validations7:33
Apply Spring Boot JPA bean validations to an entity, enforcing not null names, email format, min and max values, negative values, and past date constraints via the request body.
More Validation related Annotations8:39
Explore how to apply and combine multiple validation annotations in Spring Boot, including not null, not blank, pattern, size, email, digits, min/max, and future dates, to enforce data integrity.

Different types of Repository Custom Methods/Queries33:00
@Modifying Annotation for update, delete Custom Queries11:08
How to use Derived Query Methods?18:22
Master derived query methods in Spring Boot with JPA to implement custom repository methods, including find by name and country, ignore case, contains, count, and top results.
Custom Query(Native Query) returning List of Maps from Repository Methods5:20
retrieve records using a native query that returns a list of maps from a repository method, mapping country names to user names, with service and controller integration.

Spring Boot 2.x Actuator27:42
Explore spring boot actuator for remote monitoring, exposing health, metrics, logs, memory, and other management endpoints via configuration properties, with security considerations and runtime control.
How to Customize Spring Boot 2.x Actuator7:12
Create custom Spring Boot actuator endpoints and extend existing ones with additional details from various sources, including health indicator, enabling read and write operations without extra configuration or dependencies.
