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

• Containerization (Docker)

  • The course shows three(3) ways we can containerize our application. i.e create image

  • 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.

Who this course is for:

• This course is for all Java developers: beginners to advanced who want to build projects that easily ship from monolith to microservices
• For developers/Engineers who want to properly structure a projects very neatly
• The Course is idea for all Java/ Spring Developers and intending Spring Developers
