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.

Chapter 4: Developing Cloud-Native Applications

MicroProfile 4.1 builds on some Jakarta EE (formerly Java Enterprise Edition) application programming interfaces (APIs)—specifically, Jakarta RESTful Web Services (JAX-RS), Jakarta Contexts and Dependency Injection (CDI), JavaScript Object Notation Processing (JSON-P), and JSON Binding (JSON-B). Using only these technologies, it is possible to develop a perfectly capable cloud-native application. The MicroProfile community added a type-safe mechanism for invoking RESTful services known as the MicroProfile Rest Client. These technologies are essential for building Java-based microservices that can interoperate in the cloud. Learning to use these technologies will enable you to build robust and secure Java microservices.

In this chapter, we will explore all of the following topics:

  • Developing a RESTful service with JAX-RS
  • Managing the payload with JSON-P and JSON-B
  • Consuming RESTful services with the MicroProfile...
