A simple DropWizard extension for integrating Guice via a bundle. It optionally uses classpath scanning courtesy of the Reflections project to discover resources and more to install into the dropwizard environment upon service start.
Simply install a new instance of the bundle during your service initialization
public class HelloWorldApplication extends Application<HelloWorldConfiguration> {
public static void main(String[] args) throws Exception {
new HelloWorldApplication().run(args);
}
@Override
public void initialize(Bootstrap<HelloWorldConfiguration> bootstrap) {
GuiceBundle<HelloWorldConfiguration> guiceBundle = GuiceBundle.<HelloWorldConfiguration>newBuilder()
.addModule(new HelloWorldModule())
.setConfigClass(HelloWorldConfiguration.class)
.build();
bootstrap.addBundle(guiceBundle);
}
@Override
public String getName() {
return "hello-world";
}
@Override
public void run(HelloWorldConfiguration helloWorldConfiguration, Environment environment) throws Exception {
environment.jersey().register(HelloWorldResource.class);
environment.healthChecks().register("Template", TemplateHealthCheck.class);
}
}
Lastly, you can enable auto configuration via package scanning.
public class HelloWorldApplication extends Application<HelloWorldConfiguration> {
public static void main(String[] args) throws Exception {
new HelloWorldApplication().run(args);
}
@Override
public void initialize(Bootstrap<HelloWorldConfiguration> bootstrap) {
GuiceBundle<HelloWorldConfiguration> guiceBundle = GuiceBundle.<HelloWorldConfiguration>newBuilder()
.addModule(new HelloWorldModule())
.enableAutoConfig(getClass().getPackage().getName())
.setConfigClass(HelloWorldConfiguration.class)
.build();
bootstrap.addBundle(guiceBundle);
}
@Override
public String getName() {
return "hello-world";
}
@Override
public void run(HelloWorldConfiguration helloWorldConfiguration, Environment environment) throws Exception {
// now you don't need to add resources, tasks, healthchecks or providers
// you must have your health checks inherit from InjectableHealthCheck in order for them to be injected
}
}
Please fork an example project if you'd like to get going right away.
Enjoy!
