dropwizard-guicier

A Dropwizard bundle to handle Guice integration.

Usage

    <dependencies>
        <dependency>
            <groupId>com.hubspot.dropwizard</groupId>
            <artifactId>dropwizard-guicier</artifactId>
            <version>1.0.2.0</version>
        </dependency>
    </dependencies>

Simply install a new instance of the bundle during your service initialization

public class ExampleApplication extends Application<ExampleConfiguration> {

  public static void main(String... args) throws Exception {
    new ExampleApplication().run(args);
  }

  @Override
  public void initialize(Bootstrap<ExampleConfiguration> bootstrap) {
    GuiceBundle<ExampleConfiguration> guiceBundle = GuiceBundle.defaultBuilder(ExampleConfiguration.class)
        .modules(new ExampleModule())
        .build();

    bootstrap.addBundle(guiceBundle);
  }

  @Override
  public void run(ExampleConfiguration configuration, Environment environment) throws Exception {}
}

Features

• Injector is created during the run phase so Configuration and Environment are available to eager singletons (injector is also created with Stage.PRODUCTION by default)
• Modules added to the GuiceBundle can extend DropwizardAwareModule which gives them access to the Bootstrap, Configuration, and Environment inside of the configure method. This can be used to do conditional binding, for example
• Any Managed, Task, HealthCheck, or ServerLifecycleListener bound in Guice will be added to Dropwizard for you, for example (must be eager singletons for this to work)

Examples

There is an example project you can clone and play with if you'd like to get going right away.

Enjoy!
