Dropwizard Courtesy Client Sample App

Sample project for Dropwizard 1.0.0 demonstrating the courtesy client pattern.

The sample service requires Java 1.8 and Gradle 2.9 or higher

For a sample service compatible with Dropwizard 0.9.3 check out the dropwizard-0.9.3 release

Project Structure

The project contains three subprojects hosting the API, the application (service), and a courtesy client. Individual project structure is based on the Dropwizard recommended model. This results in the following package layout:

com.sample
    |- api
    |- client
        |- configuration
    |- service
        |- domain
        |- health
        |- resource
        |- service

Build Artifacts

There are three artifacts produced during a standard build:

1. sample-service
2. sample-client
3. sample-api

The dependencies are set up as follows: service -> api <- client. This allows us to provide downstream services with the client as a courtesy, saving effort implementing the service's interface but without depending on it directly. Downstream services need only update their version of the client if a new version of the client has been produced because the API interface implemented by the service has changed.

Run Dropwizard service

Build, package and run the service:

./go

To unit test:

gradle test

To integration test:

gradle integrationTest

The integration test provided currently does only the following:

1. Run the service
2. Call the service HTTP API using the client
