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 […]
In my latest tutorials I built a small web application using a database to retrieve some data and show it on a simple webpage. In this tutorial I will be using the same codebase, but this time I will be using Docker containers to run the application.
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 […]
Three years ago I wrote this tutorial. Things have changed in the Java and Spring landscape, so let’s see how much easier it is now to write a simple Spring webapplication.
In the next few weeks I will be writing a small web application and in these articles I’m going to explain certain aspects of it. Previous time I mentioned how you could secure your REST API (partially), and this time I will be talking about how to validate the input you send to the REST […]
In the next couple of weeks I’m going to develop a small idea sharing/voting application, using several common concepts in web development. First of all, I’m going to write and secure a REST API with Spring Security.
