Event Driven Microservices using Spring Boot | Full In-depth Course

An event-driven architecture uses events to trigger and communicate between decoupled services and is common in modern applications built with microservices. An event is a change in state, or an update, like an item being placed in a shopping cart on an e-commerce website.

Its so beautiful BRILLIANT and full of passion and integrity that its one out of millions quality work in microservices understanding that like us who are very naïve and new in this field, find it sky high inspiring to become able to take control on the reverse mechanism of the microservices when a single microservice fails to let all the other microservices need to take care of integrity of data and states of the objects. Heartful of thanks and wishes for you Shabbir Dawoodi, you are just a GENIUS!

[@MRXMrx-gg2xi]

I don't understand the write side of CQRS, if we have two database (write and read db) and would like to save an domain object in read database where should we persist it? in command handler? Because you only update the read database by event handler, right?

[@arturtyan93]

nice course, very helpful if you didn't face with event driven microservices architecture

[@guillermofernandezraboso6403]

Fantastic course and really well explained man!
Just to leave it requested, it would be great if you could expand the course with Spring Cloud, centralized logging and circuit breaker tools. Also, I would love to see how you managed the notification service and the rest of the missing compensations.
Anyhow, you are the best! Thanks a lot!!

[@updownftw]

Hi Shabbir, the CQRS example you took is sharing the same database. Isn't the whole point of CQRS is to make the applications loosely coupled? How do I connect my command and query databases and make sure they are in sync?

[@ThaileangSung]

Awesome! Your tutorial is very practical, which I like.

Awesome course bro!! Really looking forward to seeing some course that uses Kafka as well.

please make some courses on Front-end as well most preferably with Angular.
It helps lots of Full stack developers to improve their skills.

[@tejabtitare5169]

Hands on it guru. 👏🙏🙏

[@naeembilal]

This is not event driven but a very good example of event sourcing, my point of view this is too early as event sourcing should be part of some framework so the developers should focus on the key work they assigned, may be an annotation on the Controller or Spring configuration also tracing needs to be incorporated to link the events in the multithreaded environment, which leads to another problem of single point of failure, unless you have event server backed by the load balancer but then due to stateless affect sequence of sates will be present of different server and become bigger issues to playback the sequence of simple events say customer placed the orders and before the order process triggered how many events have been sourced.

Hey, Current axon framework version is 4.5.8. As per your instructions, I've used 4.5.3. But i'm getting the error as follows "Error creating bean with name 'entityManagerFactory': If I use 4.5.8 version, i'm getting the User object as NULL from Userservice. Not sure how to fix this. please help me.

[@MultiSudd]

Btw, I got it worked. I used the axon framework as 4.5.3. I need to change the spring boot version as well. I used the same version as you have used. It is now working fine for me. Thanks for the video.

[@Why_Zed]

Thank you

[@happy.s1ngh]

Great Tutorial! Do we need to create 4 different services for SAGA? Can we create all the 4 services as packages in the same service? Also is it a good idea to follow SAGA & CQRS only for order, payment & shipment services and use only simple MVC pattern for all the other CRUD operations of User, Address, Business, etc tables?

Getting below error while starting application
Description:
Parameter 0 of constructor in com.dailycodebuffer.ProductService.command.api.controller.ProductCommandController required a bean of type 'org.axonframework.commandhandling.gateway.CommandGateway' that could not be found.

How to resolve ?

[@masterinJava1611]

Error :
"OUT_OF_RANGE: [AXONIQ-2000] Invalid sequence number 0 for aggregate 0, expected 1"

[@abdelghafourboufenzi213]

it makes no sense to have 200 as a response of the postMapping when having an exception in your example starting from 1:01:00, it should be a 400 with a response message, i tried to use controllerAdvice with your example but it doesn't work, i'm getting some weird response and also the postMapping get's executed immediatly when running the application

[@Talaria.School]

Uncle Roger loves this widjo.

[@Rameez-Raja]

Thanks for your detailed description. One question which I have is, since you are running all the services in different port, how each service know each other with configuring the end point? Is it through command handler when you submit the send method
pls clarify

[@on611]

Hi sir, how to respond to a value other than String to the client when executing in the command controller. For example, when a user posts email, password -> command controller completes authentication -> responds with some user information along with token?

[@arioafrashteh6767]

Thanks but, about the exception handling:
1- Your error message is so general 58:07
2- Your banana sample is fine why you put an exception after the save method! 59:09 if this is just a sample of exception handling it's confusing.

[@DailyCodeBuffer]

Sorry for the confusion
I will try to be precise from new videos
Thank you so much for feedback 🙏🏻🙏🏻

[@ramasamyramasamy2423]

after finishing of the transaction, agreed with the exception thrown and the record is not saved. But if I stop and restart the springboot, the "on" method is automatically called. Anyhow its not saved but how to avoid the calling of the "on" method in event handler. Or how to delete the event of the save of "Apple" record from axon ?

[@АлексейШитиков-с7п]

Your aggregate identifier is not unique. Change line
@AggregateIdentifier
private String productId= UUID.randomUUID().toString();
It will help. Don't know why in author example there is no error. May be he fixed it without showing us.
