The Baeldung Weekly Review 11
Last updated: May 9, 2018
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.

Java
This is an exciting week – the week when Java 8 is finally out, so it makes sense to start here:
=> JDK 8: General Availability
=> Oracle Releases Java 8 at EclipseCon
Java 8 is out. Nuff said.
=> Java 8 Tutorial
And here’s a good, clean Java 8 Tutorial to guide you though all that goodness.
=> Java 8 Friday Goodies: Lean Concurrency
The fantastic Java 8 series from JOOQ is coming out consistently with good reads – this time with a look at the concurrency improvements that are now out in Java 8.
=> The Optional Type API
A good look at API design with the Scala, Guava and now Java 8 Optional type.
=> Getting JUnit Test Names Right
Interesting read about a problem I struggled with countless times – picking the right names for my tests.
Spring
=> Introducing Spring Test MVC HtmlUnit
MVC HtmlUnit is getting to be a thing – which is an interesting blend of two technologies I used in the past, but never though I’d see side by side. Alas, here we are, and it looks promising.
=> Adding Social Sign In to a Spring MVC Web Application: Integration Testing
If you’re building anything with Spring Social, this series is a must read.
=> Spring Context the Grails Way
There is a plethora of options for bootstrapping a Spring Context – and this is one of the more interesting options available.
Technical
=> TDD and Modeling a Chess Game
This new article continues what the previous “What TDD Is and Is Not” started – a thorough look at applying TDD on an actual usecase. But what makes this “the one to read this week” is that this is not your run of the mill TDD toy example but a real one, with real choices to be made, so thinking through it is well worth it.
=> Trying out TLS for HTTP:// URLs
This is a close second – transparent HTTPS in the form of Opportunistic Encryption. When/If it will get implemented into the major browsers, it will be nothing short of inspired.
=> Trigger Continuous Delivery every GitHub commit
Useful guide to have available if you’re setting up a CI.
Finally, Martin Fowler’s Microservices page is coming together into a complete picture:
- => Decentralized Governance
- => Decentralized Data Management
- => Infrastructure Automation
- => Smart endpoints and dumb pipes
General Musings
=> The Microservice Architecture Sounds Like Service-Oriented Architecture
This page is clearly having an impact in the industry; I am personally following it closely and learning a lot, and it looks like I’m not the only one. Very interesting read about the process of learning and changing your mind. Being willing to change your mind is so very important to do any kind of learning and growing – at least it is for me – so this was especially nice to read.
=> Afraid of reopened issues?
Reopened issues are a fact of life – and Vlad’s thinking through the possible reasons is worth reading.
