Baeldung Weekly Review 3
Last updated: October 1, 2021
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:
Handling concurrency in an application can be a tricky process with many potential pitfalls. A solid grasp of the fundamentals will go a long way to help minimize these issues.
Get started with understanding multi-threaded applications with our Java Concurrency 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.
You can explore the course here:
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 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
>> Spring and Angular JS: A Secure Single Page Application
>> The Login Page: Angular JS and Spring Security Part II
A solid, detailed introduction to securing a single page app with Angular on the front end and Spring Security on the back end. This is going to be an important reference going forward.
>> “Configuring It All Out” or “12-Factor App-Style Configuration with Spring”
Configuration is easy to get wrong. It’s always a balancing act of how much flexibility you want and how much complexity you’re comfortable with. This article gives you the tools you need to do a good job reaching that balance.
Lots of Spring goodness this week (this is why Spring is the first section of the review on this one).
>> Getting Started with Gradle: Creating a Multi-Project Build
Continuing the Gradle series, this article goes into detail on how to structure a multi-module build.
I haven’t jumped on the Gradle bandwagon yet, but if I do, I’ll definitely be coming back to this article for a step-by-step guide on how to do it.
Some very cool presentations:
-
>> Making Spring Boot Even Groovier
-
>> Inside spring.io: a Production Spring Reference Application
-
>> Caching and Messaging Improvements in Spring Framework 4.1
-
>> From 0 to Spring Security 4.0
-
>> Spring Framework on Java 8
And the interesting releases of the week:
2. Java
>> Testing with files and directories in JUnit with @Rule
I wasn’t aware of this cool JUnit @Rule for intelligently working with the filesystem – looks helpful.
>> A beginner’s guide to Java Persistence locking
A high level intro to JPA 2.0 / Hibernate locking.
>> Java 8 Streams API as Friendly ForkJoinPool Facade
A few fun exercises using the new Streams API to submit work to a ForkJoinPool.
>> Everything You Need To Know About Default Methods
A good theoretical reference on default methods, aiming to basically cover everything there is to be covered on the subject.
Would benefit from a few more code examples showing how some of the scenarios/examples work. Must have taken a heck of a long time to put together.
3. Technical and Musings
>> The God Login
A thorough analysis of what a good authentication process looks like, what problems it solves and how it can be made so that it doesn’t annoy the crap out of your users.
>> Dissecting an interview question: math is hard
A fun problem of adding to number together. Yeah.
4. Comics
And the weekly dose of some Dilbert greats:
>> Adding 2 more people to a project
>> It couldn’t be worse
>> Minor website changes
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.
