Running Location Simulating system is a back end web real-time microservice system, using Java, Spring Boot, Spring Data, Spring Cloud, RabbitMQ, MongoDB, and H2

• RabbitMQ: process payment asynchronously for preventing a hard handling with too many orders

• Eureka: services registration and discovery

• Hystrix: services fall and gracefully degrade

• Running location service : Frontend can use running location service to initialize all locations during startup

• Running location simulator: Simulating running locations defined in JSON file and scheduled to run. Sending current location, including runningId, location lat, location logitude, runner status, speed, and heading to location distribution service

• Running location distribution service: Publish current locations to locations queue in RabbitMQ

• Running location updater: Consume current locations from locations queue in RabbitMQ, and setup Websocket connect and push locations to client

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Java JDK 1.8
Maven
Docker

Change your current Location to running-simulating-system

$ cd ../running-simulating-system

Create executable jar files

$ mvn clean install

Go into each module target folder and run jar file by run following Services' introduction order.

$ java -jar [jar file]

Integration test and MockMvc test run automatically while building jar files.

Use Google App Postman and to test

• Supply-location-service test :

  1. Set Postman's Http method as Post

  2. Input url: http://localhost:9001/bulk/supplyLocations

  3. Upload running location JSON file

• Running-location-simulator test:

  1. Set Postman's Http method as PUT

  2. Input url: http://localhost:9006/api/{simulation/cancel}

  3. To start or end simulation

Open eureka, rabbitMQ, and hystrix corresponding urls to confirm every microservice run correctly
