Using the Netflix stack with Spring boot: Ribbon

In my last article I gave a basic introduction into the concepts of a service oriented architecture (SOA) and microservices. I also made a small example about a service registry and how Netflix is involved into microservices with tools like Eureka. However, the story was quite unfinished, since we only made it possible for microservices […]

Using the Netflix stack with Spring boot: Eureka

A while back I wrote a simple REST service with Spring boot. While this is quite common, we’re also seeing the word “microservice” pop up more often as well. But what is a microservice and what does Netflix has to do with it and more specifically, what is Eureka? Well, in this article I will […]

Utilizing cache abstraction with Spring boot and Ehcache

Caching is a very common operation when developing applications. Spring made a neat abstraction layer on top of the different caching providers (Ehcache, Caffeine, Guava, GemFire, …). In this article I will demonstrate how the cache abstraction works using Ehcache as the actual cache implementation.

Exploring contract first options with Swagger

In my latest tutorial I documented a simple REST API with Swagger and Springfox. While this approach certainly showed how valuable documenting your REST API can be, we aren’t really “done” yet. In the great world of SOA we know something like “contract first development”, in which we initially describe the web service (using WSDL) […]

Documenting your REST API with Swagger and Springfox

In my last tutorial I built a REST service together with a REST client. Like I said before, REST services are pretty great to allow reuse of your operations, however, to become reusable, you’ll have to properly document the available endpoints in your REST API, which endpoints there are, what they can do, what they […]

Consuming REST API’s with Spring

In the last tutorial we created a small REST API. So now that the “producing REST API” step is completed, it’s time to start consuming it in another Spring boot project. Last time we’ve already set up a module for this project, called spring-boot-rest-client.

Producing REST API’s with Spring

In the past couple of weeks I’ve written a few simple applications using Spring boot. With Spring MVC it’s also quite easy to serve REST API’s. In this article I’ll show you how to create such a REST API and how to consume one using RestTemplate.

CloudFlare, good or bad?

If you’re a developer like me and you spent some of your time on Reddit or StackOverflow, you probably might have encountered some articles about CloudFlare last week, like CloudFlare is ruining the internet (for me) and CloudFlare is ruining Stack Overflow for me with its recaptcha. Reading these articles made me want to evaluate […]

Handling forms with Spring Web and JSR-303

Up until now I’ve written several tutorials already about creating some readonly Spring boot application, but what’s cool about that? Eventually you’ll have to add/update some data in your application. In this example I’ll show you how you can do that with Spring Web and JSR-303 bean validations.

Internationalization (i18n) with Spring

When developing applications, it can be interesting to put labels in a separate properties file, so that they can be re-used. For example, we often noticed that within our applications there were slight variations on specific words, which broke consistency. The easiest way to solve that is to centralize these labels. Another benefit you get […]
