Course content

1 section • 25 lectures • 3h 11m total length

Introduction to the Course & PDF part 11:33
Install JDK, IntelliJ, JSON, Postman & Maven5:15
Install and configure open-source tools—Zulu JDK, IntelliJ Community Edition, JSON viewer, Postman, Maven, and Postgres—then set JAVA_HOME and PATH for a complete development setup.
Install PostgreSQL Database7:05
Install and configure PostgreSQL on Windows, including downloading binaries, setting PATH, initializing the database, starting the server, and using pgadmin 4 to manage and query.
Setup Spring Boot4:04
Create a Spring Boot initializer project on start.spring.io by selecting Maven, Java 22, and dependencies (Spring Boot DevTools and Spring Web), then open in IntelliJ and configure the SDK.
A few things about the setup1:39
Explore setting up a Spring Boot project by understanding the main application annotation, component scanning, and Maven dependency management, and begin by creating a controller.
Our First Controller7:59
GET Mappings5:41
Learn to configure a base path with a Spring Boot rest controller and get mappings, call api paths like /api/hello and /api/world, and use request params with defaults returning json.
Domain, Exception, Service & Repository20:08
Student Controller - Bringing it together9:16
Troubleshooting1:11
Qualifier2:14
Post & Find by ID10:14
Custom Queries12:29
Learn how to implement and test custom queries in a spring boot app with Postgres, extending jpa repositories, adding upsert, delete, and date-based search in a rest api.
One Student Many Tasks5:46
Build a one-to-many bidirectional mapping where every student can have multiple tasks, adding a task class, and configure fetch, cascade, and JSON references for serialization.
One to Many relationship26:40
Explore a practical one-to-many bidirectional mapping between student and task domains in Spring Boot, covering entity relationships, DTO usage, JSON references, and repository-service-controller patterns to manage tasks.
Many to Many relationship14:24
Explore many-to-many relationships by modeling a linking table between students and courses, enabling each student to enroll in multiple courses and each course to include multiple students.
Set vs List4:02
Explore how converting sets to lists solves fetch issues in Spring Boot for many-to-many relationships, enabling proper enrollment of students in courses and tasks.
Actuator3:25
Logging2:17
Validation & Exceptions11:14
Explore Spring Boot validation with inbuilt validators for fields like email and name, using not null, size, and email annotations, and handle errors via a global exception handler.
Swagger3:36
For swagger use version 2.7.0 instead of 2.2.0
Testing with Mockito9:55
Use Mockito for mock testing in a Spring Boot app, testing controllers without hitting services or repositories. Inject mocked services to demonstrate arrange, act, and assert in tests.
React UI - Display9:32
React UI - POST7:25
Inversion of Control / PDF and Code of Project4:01
Explore dependency injection and inversion of control in spring boot by comparing constructor injection and field injection, showing how final fields enable required arguments constructors and automatic injection.
