Would you like to easily transition your application to microservices having started as a monolith? Then this course is for you

It teaches you from scratch all you need to know about Spring Modulith. We break entities and their related objects into modules and use existing Modulith rules to enforce compliance.

You will master why and how to use Spring events to communicate between modules.

Also covered are mirroring existing database with Spring Data JPA.

The course also explains pragmatically how to save events:

Successful events for metrics through illustration.

Failed Events: on how to retrieve, APIs made available to trigger the rerun.

Created a custom class to show how we can use a scheduler (cronjob) to rerun the events.

also manual triggering of the failed event through an exposed method.

Inside the Course, you will learn about and/or highlight a bit on:

Spring Events

Spring Data JPA

we likewise ran the application via Docker commands in the terminal

clear usage on how services communicate within the containerized environment

we leveraged Docker networks clearly defined in the compose file

CI/CD Pipeline using Git actions

Kubernetes Deployment

PostgresDB

Custom Exceptions and Validations

Modulith Metrics

Java records

Spring Boot Starter Docker Compose and how to use it in development and Integration Tests.
