Source code from the Reactive Microservices in Java book

Reactive Microservices in Java

This repository contains the source code from the Reactive Microsevices in Java - Asynchronous, Elastic, Resilience Applications book. It contains the source code shown in the book as well as other examples.

The repository is structured as follows:

• Hello Vert.x - the Vert.x Hello World
• Packaging Examples - build Vert.x application using any tool
• Reactive Programming (RX Java 1) examples
• Microservices - the different microservices built in the book
• OpenShift - the microservices built in the book running on top of OpenShift

Each directory contains the instructions to build and run the module.

HelloConsumerWithCircuitBreakerHttpVerticle. Circuit Breaker don't rediscover endpoint after reset

When following the book walkthrough, when scaling to 0 pods the hello-microservice to open the circuit and later rescale to 1 pod to see the circuit closed again, it won't close as the Service Discovery code won't execute, so it wouldn't find the new pod. Some code has to be attached to the halfOpenHandler to re-discover the service.

No handlers for address hello

I am trying the message-based example, but after doing everything I get that error when I visit localhost::8082.
Also, I do not see any resources/ folder in the generated project.
By the way, this is created via start.vertx.io page and with Gradle, rather than via Maven, as mentioned in the book. Is it something to do with the configuration of Inifinispan?

Wrong artifact in poms

These two poms have "hello-consumer-microservice-message" as their artifactId instead of their own names

microservices/hello-consumer-microservice-timeout/pom.xml
microservices/hello-microservice-faulty/pom.xml

I'll submit a PR shortly

Fix jar names in READMEs

The following readmes use the wrong jar names in the java commands

microservices/hello-consumer-microservice-timeout/README.md
microservices/hello-microservice-faulty/README.md

I will submit a PR to fix these

typo in healthcheck maven dependency

Hi,

I think that there is a typo in the following pom.xml file

openshift/hello-microservice-openshift-health-checks/pom.xml

The healthcheck maven dependency should be

<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-health-check</artifactId>
</dependency>

i.e. vertx-health-check rather than vertx-health-checks

Cannot extract main class to startup

I am getting the following error when I run "mvn fabric8:deploy -Popenshift". Any idea of what could be the problem?
