Spring Boot is the modern framework to develop Java/JVM applications using an opinionated view of the Spring platform and many third-party libraries.
When developing Spring Boot applications, I often need to check if property values are correctly received from configuration files, environment variables, or other sources. There are various ways to perform this task. This article will present my solution for dumping the Spring Environment using a simple application listener.
In Spring Boot applications, it’s not uncommon to configure a value representing a size in bytes, for example, a buffer size, a file size limit, etc. In this article, I will describe how to use the DataSize class provided by Spring Framework to configure and handle data size values.
In the previous article Spring Boot: configuring the Actuator “info” endpoint, I explained some fundamental concepts about configuring and using the “info” endpoint provided by Spring Boot Actuator. In this article, it’s time to see how to implement custom info contributors.
Actuator is a software module you can add to any Spring Boot project to expose many features for monitoring and managing the application. This article describes how to use and configure one of the essential features of Actuator, the “info” endpoint.
If you have been using Spring Boot for a while, sometimes you may have encountered a failure when launching an application. One common and frequent case is when the application is already running, and you try to re-run the application (or another application that uses the same server port). In this case, Spring Boot logs…
Spring Boot directly supports three well-known JSON binding libraries: Jackson, Gson, and JSON-B (note that the latter is, more precisely, a specification). JSON binding is typically used in REST web services, but you can use it in several other contexts. In this article, I will explain how to integrate these libraries in Spring Boot (mainly…
