Practical Cloud-Native Java Development with MicroProfile

By: Emily Jiang, Andrew McCright, John Alcorn, David Chan, Alasdair Nottingham

Overview of this book

In this cloud-native era, most applications are deployed in a cloud environment that is public, private, or a combination of both. To ensure that your application performs well in the cloud, you need to build an application that is cloud native. MicroProfile is one of the most popular frameworks for building cloud-native applications, and fits well with Kubernetes. As an open standard technology, MicroProfile helps improve application portability across all of MicroProfile's implementations. Practical Cloud-Native Java Development with MicroProfile is a comprehensive guide that helps you explore the advanced features and use cases of a variety of Jakarta and MicroProfile specifications. You'll start by learning how to develop a real-world stock trader application, and then move on to enhancing the application and adding day-2 operation considerations. You'll gradually advance to packaging and deploying the application. The book demonstrates the complete process of development through to deployment and concludes by showing you how to monitor the application's performance in the cloud. By the end of this book, you will master MicroProfile's latest features and be able to build fast and efficient cloud-native applications.

Consuming GraphQL services with client APIs

The client APIs are not officially part of the MP GraphQL specification yet. At the time of writing, these APIs are still under development in the SmallRye GraphQL project, with the intention of formalizing them into the specification.


Since these APIs are not official yet, they are subject to change. The information in this section pertains to the SmallRye GraphQL version 1.2.3 client APIs. These APIs may change when added to the official MP GraphQL specification, so please check with the official documentation at for any changes.

The MP GraphQL project intends to support two flavors of client APIs. Similar to the JAX-RS client and the MicroProfile REST client (see Chapter 4, Developing Cloud-Native Applications), there is a dynamic client API and a type-safe client API. As with the JAX-RS client, the dynamic client allows users to specify the nitty-gritty details of the...
