Baeldung Weekly Review 34
Last updated: October 23, 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.

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
>> Impulse: “Adventures On The Road to Valhalla” [codefx.org]
Detailed breakdown of the current progress and state of Project Valhalla – which is supposed to land in Java 10 or 11.
The article is following a recent talk that I shared in the review from last week.
>> Parameterized integration tests with Spring JUnit Rules [codeleak.pl]
Practical and timely illustration on how to put the new JUnit rules from Spring 4.2 to good use.
>> Migrating a Spring Web MVC application from JSP to AngularJS [spring.io]
A very nice guide on migrating an MVC style app to a REST API, which then makes possible moving from Server Side JSP to full Client Side AngularJS. Very nice.
Also worth reading:
-
>> Java Style Guidelines (Draft) [java.net]
-
>> Getting Started With Gradle: Creating a Spring Boot Web Application Project [petrikainulainen.net]
-
>> Embedding ElasticSearch In a Spring Application [geekabyte]
-
>> More DevOps for Spring Boot [frankel.ch]
-
>> Internationalization in Spring Boot [spr.com]
Webinars and presentations:
-
>> Takipi’s Tal Weiss Talks Candidly About Enterprise Debugging Practices (+ announcement) [infoq.com]
-
>> Protocols of Interaction: Best Current Practices [infoq.com]
Time to upgrade:
-
>> Hibernate ORM 5.0 has goes Final! [in.relation.to]
-
>> Spring AMQP 1.5.0 Release Candidate Available and >> Spring Integration 4.2 Release Candidate is Available [spring.io]
-
>> Spring Boot 1.3.0.M4 Available Now [spring.io]
2. Technical
>> Introduction to Akka Actors [codecentric.de]
Continues the introduction to Akka series with this well put together second installment.
>> Will there be a Distributed HTTP? [mnot.net]
Really good, in-depth writeup on the architecture of the web, potential privacy risks and one possible way to move forward.
>> Eliminating Roundtrips with Preconnect [igvita.com]
Very cool new spec to make the web faster.
>> Call me Maybe: Chronos [aphyr.com]
Another fantastic, in-depth read in the Call me Maybe series. I’m really enjoying these in-depth writeups of technologies I’m actually using.
Also worth reading:
-
>> Using JSON in a low latency environment [vanillajava]
-
>> Thomas Müller Unveils How HSQLDB Evolved into the Popular H2 Database [jooq.org]
3. Musings
>> The parable of the 57.6k modem [dandreamsofcoding.com]
Don’t get trapped in a local maxima.
>> Developers Who Can Build Things from Scratch [aaronstannard.com]
Learning to put your work out there often takes being intentional about it. Otherwise, it’s far to easy to land in a job where that simply isn’t part of the engineering culture.
I didn’t do to much of that in the first 3 years of my career; so, after that, I made it a point to prioritize the “release early and often” culture when I took on my next job. So yeah, a good quick write-up with a few solid take-aways.
>> The difference between time and attention [signalvnoise.com]
A good distinction – when you’re asking for someone’s time, you’re also asking for their attention. And though they might have the time, they might not have the attention.
Also worth reading:

>> Don’t Be a Human Resource [daedtech.com]
-
>> What Functional Programming Is + Why It Makes You Better [functionalworks]

>> You don’t have any friends, do you?
>> Said the engineer with no budget
5. 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.
If not – you can share the review and unlock it right here:

Usually the weekly pick isn’t pointing to my own stuff.
But since I recently made the official announcement and publicly committed to hard dates – here’s what I’m working on (and will be for the next few months):
