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.

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
>> Reactive Programming with Spring 5.0 M1 [spring.io]
Reactive support has finally been merged and is included into this cut of the 5.x version of the framework.
If you’ve been holding off from exploring it before, now’s a good time to get your feet wet.
>> Java on Steroids: 5 Super Useful JIT Optimization Techniques [takipi.com]
Interesting notes about what JVM compiler does to optimize the performance of our production code.
>> Java 8 Top Tips [jetbrains.com]
A good read with or without the IntelliJ tips. Of course if you’re using IntelliJ, it’s even better.
>> Oh No, I Forgot Stream::iterate! [codefx.org]
Quick and to the point – some nice APIs are coming along with Java 9.
>> The best way to map a @OneToOne relationship with JPA and Hibernate [vladmihalcea.com]
Hehe, the good ol’ one-to-one relationship.
>> Oracle Paves the Way to Standardise Command Line Options in the JDK [infoq.com]
A quick positive news item slotted for Java 10, among all the negative news about Java EE lately.
