dropwizard-freemarker-config

Library for using freemarker templates as configuration files. Inspiration for the library stems from Ruby on Rails framework that allows loading config/database.yml as an erb template.

Usage

Add dependency.

<dependency>
    <groupId>fi.jubic</groupId>
    <artifactId>dropwizard-freemarker-config</artifactId>
    <version>0.1</version>
</dependency>

Set ConfigurationFactoryFactory during application bootstrapping.

@Override
public void initialize (Bootstrap<Configuration> bootstrap) {

    bootstrap.setConfigurationFactoryFactory(
            new FtlConfigurationFactoryFactory<>(
                    new FtlDefaultEnvProvider()
            )
    );

}

Configuration specified when launching the packaged application jar can contain freemarker notation and has environment variables injected as env field of the model.

Examples

Database credentials with fallback values:

database:
  user: ${(env.DB_USER)!"fallback"}
  password: ${(env.DB_PASSWORD)!"fallback"}

Conditional sections. Toggling Hibernate SQL pretty printing on in development env:

database:
  properties:
  <#if (env.DEPLOYMENT_ENVIRONMENT)?? & env.DEPLOYMENT_ENVIRONMENT == "development">
    hibernate.format_sql: true
  </#if>
