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 […]
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.
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.
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.
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 […]
Recently I wrote a tutorial about mapping with MapStruct. Testing it out for the first time, I noticed several differences between MapStruct and the mapping framework that I have the most experience in, called Dozer. That’s why I’m going to make a similar tutorial to my previous one, utilizing the Dozer framework this time, allowing […]
Recently, I wrote several tutorials about Spring boot and Spring Data JPA. A common issue that appears when writing large applications is that you don’t want to use your entities on your front-end. The reason behind this is that your entity usually resembles how your database and your tables look like, while your model or […]
A few weeks ago I wrote an article about creating Docker images containing a Spring boot application, introducing both Docker, Docker Machine and Docker Compose. Today I’m going to take those images (both the application image and the MySQL image) to the cloud, using Bluemix.
In my previous tutorial I wrote a small Spring boot application that retrieved data from a database and showed it on a webpage. However, we only handled the happy path, usually stuff may go wrong when retrieving data or doing certain operations.
In my previous tutorial I made a simple application to show some superheroes and supervillains. While the application did what it should do it was pretty statically because I used some mock data. With Spring Data it’s very easy to create a simple CRUD application without the hassle of creating your own DAO’s. Spring Boot […]
