Example Cassandra Application

This simple application illustrates the use of the Pivotal Cassandra data service in a Java Spring application running on Pivotal Cloud Foundry.

Installation

Running locally

To run the application locally, you need first to create a keyspace in your cassandra.

qlsh
ected to Test Cluster at 127.0.0.1:9042.
sh 5.0.1 | Cassandra 2.2.3 | CQL spec 3.3.1 | Native protocol v4]
HELP for help.

h> CREATE KEYSPACE example WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };

The default keyspace name is example. You can change it in the application.properties file.

Running on Cloud Foundry

Create a Cassandra service instance

Find your Cassandra service via cf marketplace.

ssandra   multi-tenant   Cassandra service powered by DataStax Enterprise

Our service is called p-cassandra. To create an instance of this service, use:

 create-service p-cassandra multi-tenant cf-cassandra-example-service

Push the Example Application

First, you need to build the app. Ensure that you have got JDK v8 installed and your JAVA_HOME path correctly set.

On OSX you can set your JAVA_HOME path as follows

port JAVA_HOME=`/usr/libexec/java_home`
ho $JAVA_HOME
rary/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home

ash
 install gradle
le assemble

The example application comes with a Cloud Foundry manifest.yml file, which provides all of the defaults necessary for an easy cf push.

To push the application, just run:

 push

Usage

You can now read, write and delete “users” by GETting, POSTing and DELETEing to /users.

rl -X GET  http://cassandra-example-app.example.com/users
rl -H "Content-Type: application/json" -X POST -d '{"username":"foobar", "fname": "foo", "lname": "bar"}' http://cassandra-example-app.example.com/users

Be sure to replace example.com with the actual domain of your Pivotal Cloud Foundry installation.
