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.

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 […]

Handling errors with Spring MVC

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.

JPA made easy with Spring data’s repositories

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 […]

Testing modern web applications

If you’re a web developer like me, then you probably know that writing tests for an application means that you have to test various parts of the application. Modern web architectures usually contain the necessary front-end logic, a REST back-end and some data persistence. Having to test your application means that you want to cover […]

Rapid prototyping with Spring Boot and AngularJS

Recently I wrote an article about writing modern webapps with Spring Data REST and AngularJS. It’s not that hard to write, but it can be done even easier with Spring Boot as pointed out in the comments by Greg Turnquist. I already planned on trying out Spring Boot after some amazing articles about Spring Boot […]
