Add dependency to pom.xml

<dependency>

  <artifactId>dropwizard-morphia</artifactId>
  <version>${some.version}</version>
</dependency>

Usage

Add the following to your Dropwizard Configuration class

@Valid
@NotNull
private MongoConfiguration mongo;

@JsonProperty
public MongoConfiguration getMongo() {
    return mongo;
}

@JsonProperty
public void setMongo(MongoConfiguration mongo) {
    this.mongo = mongo;
}

Add the following to your Dropwizard Application class

private MorphiaBundle<ExampleConfiguration> morphiaBundle =
        new MorphiaBundle<ExampleConfiguration>(ExampleEntity.class) {
            @Override
            protected MongoConfiguration getMongo(ExampleConfiguration configuration) {
                return configuration.getMongo();
            }
        };
        
@Override
public void initialize(Bootstrap<ExampleConfiguration> bootstrap) {
    bootstrap.addBundle(morphiaBundle);
}


@Override
public void run(ExampleConfiguration configuration, Environment environment) throws Exception {
    Datastore datastore = morphiaBundle.getDatastore();
}

It is also possible to create an instance of MorphiaPackageBundle, which accepts package name as constructor parameter.

private static MorphiaPackageBundle<ExampleConfiguration> morphiaBundle = 
        new MorphiaPackageBundle<ExampleConfiguration>("some.package.with.entities", false) {
            @Override
            protected MongoConfiguration getMongo(DummyConfiguration configuration) {
                return configuration.getMongo();
            }
        };

Configuration

Minimal configuration requires the following

mongo:
  type: uriConfig
  uri: ${MONGODB_URI}

Currently the only available type is uriConfig. A mongodb:// uri is used to connect to Mongo. dbName can be retrived from uri, if it is specified. Otherwise you'll have to set dbName inside mongo explicitly.

Available Morhpia settings:

• storeNulls (boolean) Enables/disables storing null values in Mongo
• storeEmpties (boolean) Enables/disables storing empty values in Mongo
• enableValidationExtension (boolean) Add Hibernate Validator interceptor to Morphia
• ignoreFinals (boolean) Specifies whether Morphia will ignore final fields
• useLowerCaseCollectionNames (boolean) Specifies whether Morphia should use lowercase letters for collection names
