Spring Cloud and ServiceCall EIP Example

This example show how to use Camel with ServiceCall EIP with spring-cloud and consul.

This example includes two maven modules:

  • service that exposes a number of services

  • consumer that consumes services

Configuration

The consumer is configured in the src/main/resources/application.properties

Build

You can build this example using

mvn compile

Run the example

Using multiple shells:

  • start consul:

    $ cd services
    $ src/main/bash/consul-run-linux.sh    (for linux)
    $ src/main/bash/consul-run-osx.sh      (for mac osx)
  • start the service:

    $ cd service
    $ mvn spring-boot:run
  • start the consumer

    $ cd consumer
    $ mvn spring-boot:run

Test the example:

In a new shell:

$ curl localhost:8080/camel/serviceCall/service1
Hi!, I'm service-1 on camel-1/route1
$ curl localhost:8080/camel/serviceCall/service2
Hi!, I'm service-1 on camel-1/route2

If you keep calling the http endpoint you’ll notice they are consumed using a round robin policy and that only the services matching specific tags are consumed.

Web console

You can open the Consul web console

http://localhost:8500/ui

Where you can find information about the services and its state.
