Event hub is a project that collects various events from clients and reacts to them based on how a particular project is configured. Clients submit data via REST API. EventHub service provides client authentication and authorization and some of the most common action processing implementations. It's a very generic framework and can be extended to work with various kinds of events and event processors.
This section describes steps required to build, configure and run the application.
Install these applications on your dev machine in order to be able to build the src code:
- Java Development Kit (JDK) >= 1.7
- Optionally install SBT, or use one provided with the project
SBT is a build tool that downloads source code dependencies, compiles code, runs tests, generates scaladocs, and produces executables.
Start up SBT from unix shell:
> sbt
or if it's not on a PATH:
> ./sbt
In SBT shell type (note semicolons):
;clean; assembly
You can also run it as a single command from OS shell:
> sbt clean assembly
This will run all tests and generate a single jar file named similar to: rest-assembly-0.1.jar.
Here is a full list of commands in case you want to generate projects and documentation, etc:
> sbt clean compile test doc assembly eclipse
Look at the output to find where docs, jars, etc goes. You can open projects with Eclipse or IntelliJ afterwards. New versions of IntelliJ IDEA do not require generation of project files and can open SBT projects directly using Scala plugin.
To run compiled JAR file you should have installed:
- Java Runtime Environment (JRE) >= 1.7
- MongoDB >= 2.4
Run from your OS shell:
> java -jar rest-assembly-0.1.jar
This will run the application. In particular it will start a web server and will be ready to receive HTTP requests. Please use run scripts in production environment. They take care of runtime settings and environment, so that you don't get it wrong.
TODO
You can send requests to the web service with tools like curl on Unix systems,
or you can open the site in a browser.
