Custom ConfigSource with MicroProfile Configuration

By Community, MicroProfile, Open Source No Comments

In the previous blog post “An Overview of MicroProfile Configuration” we have seen how to start using MicroProfile Configuration and covered the most common cases where it can be used. In today’s blog post, we are going to show you one of the advanced features of MicroProfile Configuration: the ability to add your own ConfigSource. To refresh your memory, MicroProfile Config already ships with a few ConfigSources by default: file, system properties, and environment variables. What if your source of Configuration is somewhere else? Maybe a database or an API? Good news! MicroProfile Configuration allows you to create your…

By Community, MicroProfile, Open Source One Comment

When we are developing an application, it is usually a good practice to externalize some aspects of the application so we can change its runtime behavior without the need to change the code. This is what we call Configuration. A few examples may include the application language, the currency symbol, the username and password to connect to the database or a system path to store uploaded files. In a Monolithic Architecture, you may get away from Configuration. It is not a big deal to perform a couple more builds to change some parameters. In the Microservices world, it is impossible….

Overview of MicroProfile Rest Client

By Apache TomEE, MicroProfile 2 Comments

The goal of this article is to give you an overview of the MicroProfile Rest Client (aka Rest Client), how it works and the advantages you can obtain when utilizing it to implement a Java REST client. When we talk about microservices, we discuss many different architecture topics, but sometimes we forget the importance of a good client API. The Rest Client is a Java REST client based in JAX-RS 2.0, that uses its current features, but also provides a different way of interacting with the microservices. The 1.0 version of Rest Client was first introduced in MicroProfile version 1.3…
