java-getting-started

A barebones Java app, which can easily be deployed to Heroku.

This application supports the Getting Started with Java on Heroku article - check it out.

Make sure you have Java and Maven installed. Also, install the Heroku CLI.

$ git clone https://github.com/heroku/java-getting-started.git
$ cd java-getting-started
$ mvn install
$ heroku local:start

Your app should now be running on localhost:5000.

If you're going to use a database, ensure you have a local .env file that reads something like this:

JDBC_DATABASE_URL=jdbc:postgresql://localhost:5432/java_database_name

Using resources for this example app counts towards your usage. Delete your app and database as soon as you are done experimenting to control costs.

By default, apps use Eco dynos if you are subscribed to Eco. Otherwise, it defaults to Basic dynos. The Eco dynos plan is shared across all Eco dynos in your account and is recommended if you plan on deploying many small apps to Heroku. Learn more about our low-cost plans here.
