Getting Started

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

Prerequisites

JDK 1.8 - the project is written in Java.

Maven 3.x - this will handle any building, and dependencies. The Apache Maven build system can be found here.

Installing

Firstly, inside the project directory, run the following command in order to build the maven project:

$ mvn clean install 

Secondly, in the same directory, run the following command to run the project:

$ mvn spring-boot:run

Congratulations! You should now be able to visit the site at: http://localhost:8080/

More Useful Commands

In order to test the backend without a frontend, open terminal and navigate inside the project folder (where test.json is) present.:

curl -X POST  https://feedback-analysis-grp-app.herokuapp.com/feedback -d "@test.JSON" -H "Content-Type:application/json"

To skip using test.json, and specify your own:

curl -v -X POST https://feedback-analysis-grp-app.herokuapp.com/feedback -H 'Content-Type:application/json' -d '{"rating": 5, "text": "Your feedback test here"}'

Files

Root Directory

.gitignore - defines files and file types to be ignored by git 
.travis.yml - used to manipulate the travis ci pipeline & specify Heroku apps to push to
system.properties - used by heroku to specify the version of java we are using

BackendProject/

BackendProject/ - folder is for the java project files and packages - this can be accessed using Eclipse
procfile - used by heroku to tell it what the dynos should run (just what it should 'host'/ run;   
           in our case it's a compiled jar file which starts the spring server)  
pom.xml - the Maven build file, defines the build path i.e dependencies, plugins, etc.
