Spark Java micro framework based application. Spark Framework is a simple and lightweight Java web framework built for rapid development.

Spark is built around Java 8's lambda philosophy, which makes a typical Spark application a lot less verbose than most application written in other Java web frameworks.

This project uses the gradle build tool. For a quickstart you need to follow these simple steps:

git clone [email protected]:kuffel/sparkapp.git    
cd sparkapp
// To list all available tasks use
./gradlew tasks
// To create a fat jar file with the complete application 
./gradlew shadowJar              

Shadow Jar allows an easier distribution of java applictions. To start this application you can simply use this command:

cd [PROJECT_DIR]/build/libs
java -jar sparkapp.jar

For further instructions on using the Spark framework read the official documentation

The generated jar file provides some cli options to create and pass a configuriation file for your service instance.

$ java -jar sparkapp.jar -h
usage: java -jar sparkapp.jar [-c <config.json>] [-h] [-i] [-v]
 -c,--config <config.json>   Path to config.json
 -h,--help                   Show usage and help information
 -i,--init                   Create empty template config.json
 -v,--version                Display current application version

For production deployments with your own configuration just start the service with your own config.json.

To generate a new config.json run java -jar sparkapp.jar -i

If you do not provide any config this values will be uses as defaults:

{
    "name" : "sparkapp",
    "version" : [CURRENT VERSION STRING],        
    "secret" : [RANDOM STRING],                
    "port" : 9999
}
