Getting started with Axon 3 live coding webinar recording

In this first of a series of hands-on webinars you will learn about:
- how to set up the infrastructure components
- how to organize your codebase in a practical way
- how to apply event sourcing
- how to define test cases for event sourced aggregates

Really like this style of presentation more than the usual slide decks. Keep up the good work!

A small update here, the class Fixtures in the tests is now deprecated and replaced by AggregateTestFixture. Kindly take a note of it.

Very nice, just hoping this could be updated for 2024, and the latest Axon, there is a screaming lack of good docs and tutorials out there for Axon and SpringBoot

i enjoyed this session even though i'm not familiar with concept of eventbus, comandbus(cqrs) and such although i have guesses but as you know it will never same with truth.

[vinitsrivastava]

Thanks, please provide the code with annotations which are given in presentation.

[amberhoule]

thanks for this. Is the code available somewhere?

[sudarshanbarage]

Can u please share the code on github and give the path please...

i wonder if two withdrawmoneycommand handing method happens concurrently，will it as the concurrent update problems？how axon handles it？ to be more specific，if a account has a balance of 100 with overdraw limit set zero， when two withdraw 50 command almost happens concurrently. if so ，in the command hander method， will they both publish a event with remaining balance 50 ，because at the time of calculating remaining balance， the current balance is100. did i miss something here， or axon will not handle next command until current handling command has executed the event souring method part？ hope someone clears it for me.

Thank you very good hands on presentation. can you provide the sample code

[vladimirukrainian]

can't find enableAxonAutoConfiguration

[nikeshshetty]

I had to do an explicit containerManagedEntityManagerProvider.setEntityManager(entityManager)., as this was getting null
EntityManager entityManager = in GenericJpaRepository

[vladimirukrainian]

you just didn't initialize that balance ! and got -600
