That Spring allows you to easily develop REST APIs, is probably something we all know by now. With MockMvc and MockRestServiceServer, the same can be said to testing those REST APIs and clients. If you didn’t know this, then you’re at the right place to learn about it, as we’ll explore those options today!
About two years ago, I wrote a blogpost about containerizing your Spring boot application with Docker. However, some things have changed, and within this tutorial I’ll give you a more up-to-date take to containerizing your Spring boot applications.
A few years ago, I wrote an article about using WebSockets with Spring and AngularJS. However, the technologies have evolved over the years. That’s why I decided to write some up-to-date follow-up articles using the latest version of Spring boot and the latest version of the Angular framework. In this first follow-up article, I’m going […]
When handling input of a user, validation is a common task. In fact, it’s so common, that there’s even a specification for it called JSR 303 bean validation and JSR-380 which contains version 2 of the same specification. With Spring, we can utilize this specification to the fullest extent, and make validation an easier task.
As soon as you write your first web application with Spring, you probably want to secure it. Spring has a project called Spring Security that does most of the generic stuff for you. Just plug in a service that provides the user details (from a database, LDAP, …) and configure the endpoints and you’re ready […]
A few weeks back, I went to Devoxx, an annual Java conference located in Belgium. One of the few hypes there was Spring framework 5 and the upcoming release of Spring boot 2.0. With this tutorial I’ll show you how you can get started Spring boot 2.0.
Recently I wrote some articles about the various Netflix components and how they fit into a microservice architecture. In this article I will talk about the next component that is usable with Spring boot and that’s Hystrix.
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 […]
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 […]
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.
