I just released the Starter Class of "Learn Spring Security":
At the very beginning of last year, I decided to track my reading habits and share the best stuff here, on Baeldung. Haven’t missed a review since.
Here we go…
1. Spring and Java
>> Event Sourcing in Microservices Using Spring Cloud and Reactor [kennybastani.com]
All the cool kids of doing microservices – and most are left with a complex and hard to manage mess on their hands.
But there are ways to avoid that – and Event Sourcing is one of the best ways I found to get there.
>> How to verify equality without equals method [lkrnac.net]
A cool deep-dive into testing the implementation of the equals method using reflection.
>> Exploring CQRS with Axon Framework: Closing thoughts [geekabyte.blogspot.com]
The end of a long running series I’ve been following closely, all about one of my favorite topics – Event Sourcing and CQRS.
CQRS is definitely not the holy grail, but it sure comes close in some scenarios 
>> How to join unrelated entities with JPA and Hibernate [thoughts-on-java.org]
A cool addition to Hibernate I wasn’t aware of.
>> Java EE 8 MVC: Global exception handling [mscharhag.com]
A very quick and to the point intro to handling exceptions if you’re doing work with Java EE.
>> Save Time by Writing Less Test Code [petrikainulainen.net]
Some initial details about a course I’m really excited about (check out this week’s pick for more on that).

4. Pick of the Week
Almost a year ago, when I started to work on my first course, I wrote that we have so few solid courses in our ecosystem. I know from experience that it takes a long time to put together a good, high quality course – around 6 months of ongoing work – which explains why there are so few of these out there.
That’s slowly changing – Petri’s newly announced testing course is definitely going to be reference material:
>> TEST WITH SPRING
The packages have been at 50% off all week (ending today) – so if you’re into testing, pick this one up. If you’re not really into testing, then definitely pick this one up.
I’m excited about this one, not just because it’s about testing, but also about Spring (which is very cool).
