The Baeldung Weekly Review 6
Last updated: September 7, 2019
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.
Another week, another good set of articles.
There have been a lot of articles this week, and in the interest of keeping the weekly review short as well as actually valuable, I had to make some touch choices.
On Java
=> Java 8 Friday Goodies: Lambdas and SQL
This series is consistently putting out great stuff – even if you don’t use jOOQ it’s worth reading to see how Java 8 is going to make APIs a lot better.
=> Unit Testing Private Methods
This is a good writeup answering the now – age-old problem of how to best test private methods. Nice.
=> It’s About Time
Nice in-depth article about the new Date-Time API that’s going to be out soon with Java 8. This is a bit more than a week old, but I wanted to include it anyways.
On Spring
Spring Data is making headway this week (I’m most excited about the new pagination support):
- => What’s new in Spring Data Codd RC1?
- => Spring Data Elasticsearch 1.0 M1 released
- => Spring Data Couchbase 1.0 RC1 released
Technical
=> How I hacked Github again.
Every one of my weekly reviews has one article that you simply should not miss – and this detailed security analysis of a high security Github exploit is the one. Not necessarily because of this particular vulnerability (although this one was a perfect storm) – but because of the mindset that this puts you in when thinking about the security of your own applications.
=> Elasticsearch 101
Elasticsearch is one of those rare types of software that actually delivers – this article will provide a good and comprehensive introduction to it.
=> Distributed Performance Testing With Maven JMeter and Jenkins
This is a good tool to know – it enables properly tracking the performance of your application and actually knowing when you’re introducing a regression. All in all, it’s an easy thing to set up and run in your CI.
=> Git tips from the trenches
I know that one of these crops up every couple of months – and I was planning to skip it – but I found that I was taking notes of things to try out – which to me is a sign that it’s worth a read if you’re working with Git (if you’re still working with SVN, I think we should have a little talk).
General Musings
=> Why don’t software development methodologies work?
A balanced, non ritualistic approach to development methodologies – and a reminder that we should focus on being productive and producing good quality work and not obsess or get bogged down in any one process.
=> Code review best practices
Good pointers to get more value out of a code review. Here are another two good articles on the subject:
- => 11 proven practices for more effective, efficient peer code review
- => What I look for in a Code Review
Done
My plan for this review is to give you a good handful of articles to read every week – my own perspective – and filter out some of the noise.
If you have any suggestions on what I should read, to potentially include into the next review, drop me a line in the comments.
Also, if you feel that I missed a gem that came out this week, also let me know – these articles are editable at the end of the day.
Have a great week.
Eugen.
