Baeldung Weekly Review 5
Last updated: February 10, 2022
Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.
Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.
With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:
Explore Spring Boot 3 and Spring 6 in-depth through building a full REST API with the framework:
Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Spring Data JPA is a great way to handle the complexity of JPA with the powerful simplicity of Spring Boot.
Get started with Spring Data JPA through the guided reference course:
Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.
Regression testing is an important step in the release process, to ensure that new code doesn't break the existing functionality. As the codebase evolves, we want to run these tests frequently to help catch any issues early on.
The best way to ensure these tests run frequently on an automated basis is, of course, to include them in the CI/CD pipeline. This way, the regression tests will execute automatically whenever we commit code to the repository.
In this tutorial, we'll see how to create regression tests using Selenium, and then include them in our pipeline using GitHub Actions:, to be run on the LambdaTest cloud grid:

At the very beginning of 2014 I decided to track my reading habits and share the best stuff here, on Baeldung.
2014 has been quite the year, covering each week with a review. I’ve been doing a lot more reading to make sure I cover and curate stuff that has value and is actually interesting.
Let me know in the comments if you’re finding my reviews interesting and useful.
Here we go…
1. Spring and Java
>> The API Gateway Pattern: Angular JS and Spring Security Part IV
A proxy/gateway is one of the core questions you need to answer when building your Spring webapp. It helps with quite a few things – CORS being one of them. So – this forth part in the new Spring Security with Angular series unfolding over on Spring Central is a very useful reference to have.
Also – I just removed a topic from my article TODO list – and I didn’t have to write a single word 🙂
>> Spring 4 and Java 8
A quick guide on how Spring leverages Java 8 to write idiomatic code.
>> Hibernate locking patterns – How does Optimistic Lock Mode work
An interesting code-focused exploration of Hibernate optimistic locking and more importantly – the potential caveats of using it.
>> Reading Large Lines Slower in JDK 7 and JDK 8
I enjoy reading “Inspired by Actual Events” for these low level deep-dives into the Java language – and this one doesn’t disappoint. Here’s the followup to it.
>> Timeout support using ExecutorService and Futures
A quick introductory level article on working with a single thread executor and Java 8 streams.
Time to upgrade:
-
>> Spring Data Evans SR 2 and Dijkstra SR 5 released
-
>> JHipster 2.0 Released with AngularJS improvements, Liquibase diffs, and Spring WebSockets
-
>> Spring XD 1.1 RC1 released
-
>> Java 8 Auto-Update, Java 7 End of Public Update
2. Technical and Musings
>> Avoiding the Perfect Design
Pragmatism a clear “exit criteria” are missing in our industry.
You would think it’s a “young gun” mistake, but it’s not. As you’re reading this right now, someone with decades in the industry is crossing his fingers and signing off on The Big Rewrite. Why? Because – maybe this time…
So – maybe don’t do that, and maybe go read this one.
>> Agile Methodologies or Agile Software?
I try to stay away from the Agile writings here on Baeldung. That’s because most of the stuff I read on the subject is just serviceable – sometimes. With a few minor exceptions of course – such as Dan North – but he publishes once every blue moon. This one though – worth reading.
>> Taking the long view
“The long game” is an acquired skill, after you’ve been burned one to many times. And having the discipline to take the necessary steps and track the results long term can be the difference between a successful and a failed project.
>> All the Technology but None of the Love
Good advice.
>> Getting Started with AngularJS
Looks like a solid start with AngularJS – I plan to go through it over the weekend.
3. Comics
And my favorite Dilberts of the week:
>> We’re going to try something called Agile Programming
>> Please don’t hit me with your modem
>> Which answer gets us hired?
4. Pick of the Week
Earlier this year I introduced the “Pick of the Week” section here in my “Weekly Review”. If you’re already on my email list – you got the pick already – hope you enjoyed it.
