This is a collection of small and focused instances - each covering a single and well defined approach in the area of the java application development grouped by modeules. Each module is supposed to provide a separate simple instance. In this project each module presents a small simple instance of the queue stream realisation between a spring-boot restful services. A strong focus of these is, of course, the spring-cloud-stream implementation for different queue services.

This project includes the follows modules:

• number-counter - this module is a java project with simple instances of the Spring Cloud Stream implementation with Rabbit and Kafka, booth in one service;

• The simple spring-cloud-strea implementation for consuming and producing messages on booth RabbitMQ and Kafka.

• For more information on an upcoming development, please read the todo list.

• For more information on a releases, a features and a changes, please read the changelog notes.

To use it is necessary to: 1 - To deploy the additional software. 2 - To build the project. 3 - To launch the instances.

1 - To do the deployment of the additional software, execute docker compose in the root directory by the following command:

docker-compose up

2 - Wait for all software deployment to complete.

To do the full build, execute maven goal install in the root directory by the following command:

mvn clean install

To do the full build, execute maven goal install in the module directory by the following command:

mvn clean install

To do the examples, execute maven goal spring-boot:run in the module directory by the following command:

mvn spring-boot:run

This is a multi-module project. Each model is supposed to provide a separate example. That's why when you're working with an individual module, there's no need to import all of them (or build all of them) - you can simply import that particular module in either Eclipse, NetBeanse or IntelliJ IDEA and run each example in IDE.

• Oracle JDK - java development kit;
• Maven - dependency management;
• RabbitMQ - database management system;
• Docker Compose - tool for defining and running multi-container Docker applications.
