Spring Cloud Hystrix AMQP sample app

Spring Cloud Hystrix AMQP sample app

Building

Build the app with the following command:

$ ./gradlew assemble

Running on Cloud Foundry

When running on CF, the app will expect to be bound to a Circuit Breaker service instance with the name circuit-breaker. Create a service instance and push the app with the following commands:

$ cf cs p-circuit-breaker-dashboard standard circuit-breaker
$ cf push hystrix-ampq-sample

Once the app is running, browse to the app’s route URL or curl the URL to drive some traffic to the app.

Browse to the PCF App Console, click on the manage link for the circuit-breaker service, and see the traffic to the sample app in the Hystrix dashboard.

Multiple RabbitMQ connections

In the default profile the app uses a circuit breaker, which uses RabbitMQ to send metrics to Spring Cloud Turbine AMQP. With the rabbits profile enabled, the app will expect a RabbitMQ service to be bound to the app for the app’s own use. To enable this mode, follow these steps:

$ cf cs p-rabbitmq standard rabbitmq
$ cf bs hystrix-ampq-sample rabbitmq
$ cf set-env hystrix-amqp-sample SPRING_PROFILES_ACTIVE rabbits
$ cf restage hystrix-ampq-sample
