Java

Define the JestConfiguraion class somewhere in your applications configuration.

import com.meltmedia.dropwizard.jest.JestConfiguration;

...

  @JsonProperty
  protected JestConfiguration elasticsearch;

  public JestConfiguration getElasticsearch() {
    return jest;
  }

Then include the bundle in the initialize method of your application.

import com.meltmedia.dropwizard.jest.JestBundle;

...
protected JestBundle jestBundle;

@Override
public void initialize(Bootstrap<ExampleConfiguration> bootstrap) {
  bootstrap.addBundle(jestBundle = JestBundle.<ExampleConfiguration>builder()
    .withConfiguration(ExampleConfiguration::getElasticsearch)
    .build());
}

Finally, use the bundle to access the client supplier.

@Override
public void run(ExampleConfiguration config, Environment env) throws Exception {
  JestClient client = jestBundle.getClientSupplier().get();
}

Configuration

Add the jest configuraiton block to your applications config.

elasticsearch:
  clusterName: elasticsearch
  servers:
  - 'http://localhost:9200'

Formatting

This project contains formatters to help keep the code base consistent. The formatter will update Java source files and add headers to other files. When running the formatter, I suggest the following procedure:

1. Make sure any outstanding stages are staged. This will prevent the formatter from destroying your code.
2. Run mvn format, this will format the source and add any missing license headers.
3. If the changes look good and the project still compiles, add the formatting changes to your staged code.

If things go wrong, you can run git checkout -- . to drop the formatting changes.
