This is the code repository for Hands-On Enterprise Java Microservices with Eclipse MicroProfile, published by Packt.
Build and optimize your microservice architecture with Java
Eclipse MicroProfile has gained momentum in the industry as a multi-vendor, interoperable, community-driven specification. It is a major disruptor that allows organizations with large investments in enterprise Java to move to microservices without spending a lot on retraining their workforce.
This book covers the following exciting features:

All of the code is organized into folders. For example, Chapter02-govandcontribs.
The code will look like the following:
package org.eclipse.microprofile.health;
@FunctionalInterface
public interface HealthCheck {
HealthCheckResponse call();
}Following is what you need for this book: If you're a Java developer who wants to create enterprise microservices, this book is for you. Familiarity with Java EE and the concept of microservices will help you get the most out of this book.
