An example of using Jersey's dependency injection framework in a DropWizard application.

ExampleApplication.java

package io.github.derekbassett.exampledropwizard

import com.mongodb.MongoClient;

import io.dropwizard.Application;
import io.dropwizard.setup.Bootstrap;
import io.dropwizard.setup.Environment;

import org.glassfish.hk2.utilities.binding.AbstractBinder;

public class ExampleDropwizardApplication extends Application<ExampleDropwizardApplicationConfiguration> {

    public static void main(final String[] args) throws Exception {
        new ExampleDropwizardApplication().run(args);
    }

    @Override
    public void initialize(final Bootstrap<ExampleDropwizardApplicationConfiguration> bootstrap) {
    }

    @Override
    public void run(final ExampleDropwizardApplicationConfiguration configuration, final Environment environment) throws Exception {

        final MongoClient mongoClient = configuration.getMongoClientFactory().buildClient(environment, "mongo");

        environment.jersey().register(new AbstractBinder() {
            @Override
            protected void configure() {
                bind(configuration).to(ExampleDropwizardApplicationConfiguration.class);
                bind(mongoClient).to(mongoClient);
            }
        });
    }
}
