The Baeldung Weekly Review 13
Last updated: October 1, 2021
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:

Java
>> Java 8 Friday: The Dark Side of Java 8
Let’s start with this weeks Java 8 Friday goodie – about how Java 8 is rough around the edges (or at least around some edges). A must read even if you’re already using Java 8 for a while.
>> Common Misconceptions About Java
Bozho is at it again, this time with an interesting piece about misconceptions about Java – an interesting read.
>> Compiling and Running Java Without an IDE
This article is probably (hopefully) known territory for most – but I’ve seen over-reliance on the IDE in quite a few occasions, so – if you’re using your IDE exclusively to compile and run code – this is a good resource.
>> Interface Default Methods in Java 8
A good first look at the newly introduced Java 8 Default Methods.
>> JDK 9 Project
Finally – in the hoopla that is the Java 8 release, this might have flown under the radar: the Java 9 page is up.
Spring
A more quiet week for Spring (other than Spring Boot which looks to be on fire after the 1.0 release) – Spring Tool Suite and 3.5.0 has also been released (I’ve been waiting for this one).
>> Real Time Analytics with Spring
Great hour-long presentation of Spring XD (with Redis) for real-time analytics in Spring applications.
>> Building microservices with Spring Boot – part 1
Hot on the heels of the the Microservices trend that has been discussed lately – this is the first of what will be a series of articles illustrating how to build such micro-services with Spring.
Technical
>> Tracking Events Through Complex Stacks – Part 2
Useful writeup – like the one above – about running real systems in production, where you need to track things in a decent way and be able to read and make sense of your logs. Yeah – I missed the first part last week, but luckily I discovered it in time to share it in the review of this week.
>> RESTistential Crisis over Hypermedia APIs
An overview of the thornier concerns related to Hypermedia APIs over at InfoQ.
>> ReportingDatabase
Martin Follower on the many advantages, downsides and alternatives of using a different Database for reporting purposes.
Musings
>> Domain-Driven Design Revisited
Petri’s journey into DDD reignited my own interest for the subject – maybe it’s time to give it another go. Good article to get you back in the game if you’re on the fence.
>> Effective learning techniques for software craftsmen
Insightful look at the process of learning for a developer, alongside very practical advice to improve that process.
