Baeldung Weekly Review 6
Last updated: July 21, 2016
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 and Java
>> How to fix optimistic locking race conditions with pessimistic locking
Combining pessimistic and optimistic locking with Hibernate to keep the integrity of your data.
>> Top 5 Use-Cases For Nested Types
With the advent of lambdas, a deep dive, back-to-roots piece on Java nested classes is quite helpful, at least for a solid grasp of the basics.
>> Inconsistent operation widen rules in Java
Another back-to-basics with Java – a nice reminder on working with numerical primitives.
>> Programmatically Determining Java Class’s JDK Compilation Version
Another cool, low level Java article – this time about determining the version of the JDK that compiled a class. I didn’t even know it was possible.
>> Storing months of historical metrics from Hystrix in Graphite
Very cool solution for monitoring your app.
I’ve been using various permutations for monitoring – CollectD and Graphite (and more recently Kibana) being the most common – but this looks quite slick.
>> SSO with OAuth2: Angular JS and Spring Security Part V
Getting into more advanced topics with the 5th part of the AngularJS and Spring Security series – with a deep dive into OAuth and SSO.
>> Why 12 Factor Application Patterns, Microservices and CloudFoundry Matter
Complicated, manual and error prone deployment processes – that brings me back; the industry has come a long way since the early days.
And some good talks to have fun with during the weekend:
-
>> Testing with Spring 4.x
-
>> Building a Continuous Delivery Pipeline with Gradle and Jenkins
-
>> Groovy, in the light of Java 8
Time to upgrade:
-
>> Spring Security OAuth 2.0.6.RELEASE Available Now
-
>> Swagger-core v1.5.0-M1 Released! and >> Swagger-UI v2.1.1-M1 Released!
2. Technical and Musings
>> Cutting Down on Code Telepathy
“Out of Band” required knowledge to interact with an API is usually not good. A REST architecture addresses the problem via the HATEOAS constraint and Media Types. However this is not a REST-only issue, but a question to be asked when designing any API:
Does the caller require any out of band knowledge to consume the API?
If so, this is a cost; depending on the situation, it may be a cost you want to take on, but it should always be an intentional decision.
>> The Army of the New Independents
The job / employment landscape is changing, and fast. So, if you are already independent or thinking about it, this is a good one to read to give you some context.
>> Programmer IS A Career Path, Thank You
The Musings section is good advice this week – have a read.
>> Let’s Talk About Your Backups
Wake up call?
3. Comics
And my favorite Dilberts of the week:
>> The Problem with Randomness (you can never be sure)
>> Buzzwords
>> Empty Jargon
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.
