ElasticsearchJavaSample

This is a sample project to demonstrate the ElasticSearch Java API's. I use this project as part of trainings on ElasticSearch. I have developed the project using Codenvy (IDE), Travis CI (CI-CD), Coveralls (Coverage) and deployed it on Heroku (PaaS).

Project Details:

• dropwizard v0.8
• dropwizard-swagger bundle v0.7
• Java v1.7
• ElasticSearch Java API v1.7.1
• Maven v3.2.5

This project has been tested with ElasticSearch Server v1.7.1.

Prerequisites:

• Git Bash / Client
• Java v1.7
• Maven v3.2.5
• cURL or Postman or similar browser extension

Build Steps:

• Clone this repository.
• Ensure the path to Java and Maven are set.
• Run the command "mvn clean package" from the Elastic-Sample folder.
• Either use the IDE or execute the built fat JAR. Pass the following program arguements "server local.yaml".
• Once the application is running, open http://localhost/swagger in the browser. Swagger should appear as shown below.

Tips:

• Run ElasticSearch Server locally. Ensure the cluster.name in elasticsearch.yml is "elasticsearch".
• Refer the Elasticsearch Samples Gist for scripts to create indices and documents.
• Install and use the Head plugin in ElasticSearch to view the indices, documents, queries, cluster and node status etc.
• Update Maven settings to download the dependencies to a local folder on disk (instead of a network folder).
• If you are behind a firewall, update the proxy settings for Git client and Maven.

Thanks:

• Many thanks to federecio for the dropwizard-swagger bundle. It saves a lot of time and issues in dropwizard and swagger integration.
