Hocon Configuration Format

The Hocon Configuration Format extends the Vert.x Configuration Retriever and provides the support for the HOCON(https://github.com/typesafehub/config/blob/master/HOCON.md) format.

It supports includes, json, properties, macros…​

Using the Hocon Configuration Format

To use the Hocon Configuration Format, add the following dependency to the dependencies section of your build descriptor:

  • Maven (in your pom.xml):

<dependency>
 <groupId>io.vertx</groupId>
 <artifactId>vertx-config-hocon</artifactId>
 <version>4.0.0.Beta2</version>
</dependency>
<dependency>
 <groupId>io.vertx</groupId>
 <artifactId>vertx-config</artifactId>
 <version>4.0.0.Beta2</version>
</dependency>
  • Gradle (in your build.gradle file):

compile 'io.vertx:vertx-config:4.0.0.Beta2'
compile 'io.vertx:vertx-config-hocon:4.0.0.Beta2'

Configuring the store to use HOCON

Once added to your classpath or dependencies, you need to configure the ConfigRetriever to use this format:

ConfigStoreOptions store = new ConfigStoreOptions()
  .setType("file")
  .setFormat("hocon")
  .setConfig(new JsonObject()
    .put("path", "my-config.conf")
  );

ConfigRetriever retriever = ConfigRetriever.create(vertx,
    new ConfigRetrieverOptions().addStore(store));

You just need to set format to hocon.
