The Baeldung Weekly Review 5
Last updated: September 7, 2019
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:

The first week of February looks to be a productive one – some very nice resources in this one, especially around HTTP and REST.
On Spring
=> Why I like Spring @Autowired for List types
Nice and quick intro on going beyond injecting a single bean at a time – by injecting collections of beans with Spring DI.
=> Spring Framework 4.0.1 & 3.2.7 released – and 3.1.x retired
In case you missed it – the Spring Framework is moving forward – the 3.1 is officially retired and 3.2 is in maintenance mode.
=> Consuming Spring-hateoas Rest service using Spring RestTemplate and Super type tokens
On Java
=> Choosing an ExecutorService
=> ForkJoinPool: the Other ExecutorService
Very useful article on picking the right Executor Service for the job – well worth a read. Also a follow up going in-depth into the ForkJoinPool (with illustrations to top it off).
=> Java 8 Friday Goodies: Lambdas and Sorting
These posts are setting a good weekly cadence – this one is illustrating how Java 8 will change the way we sort – nice and clean.
HTTP and REST
=> Nine Things to Expect from HTTP/2
OK, if you have to pick one thing to read this week, pick this one – it delivers some great insight into how HTTP is evolving and what we should expect. An important read.
=> Measuring Up Hypermedia Types
Lays down the way of the land when it comes to picking a Hypermedia type from the myriad of options available.
Persistence
=> Hibernate Facts: How to “assert” the SQL statement count
An interesting way of keeping tabs on the queries being executed by Hibernate – I might look into this to make sure I don’t introduce any performance regressions.
Technical
=> Finding Bugs: Debugger versus Logging
Surprisingly there is still an argument about the value of good logging – a good overview between debugging and using proper logging.
General Musings
=> Two Ways to Get the Most Out of Daily Stand-up Meetings
Pragmatic points about holding an effective Stand-Up meeting. One other thing I found really effective, if the team is collocated, is to actually stand up – this keeps everyone from jumping from “problem finding” into “problem solving” mode.
Done
These weekly reviews are a lot of fun to put together, and hopefully you’re getting good articles out of them as well. If you have any suggestions on the format, or if you think I missed anything this week – let me in the comments.
Until next week.
