Camel Ehcache Blueprint example

Introduction

This example shows how to use camel-ehcache to cache messages in a Camel route.

Build

You will need to compile this example first:

mvn install

Run with Karaf

To install Apache Camel in Karaf you type in the shell (we use version ${project.version}):

feature:repo-add camel ${project.version}
feature:install camel

First you need to install the following features in Karaf with:

feature:install camel-ehcache
feature:install camel-servlet
feature:install camel-jackson

Then you can install the example:

install -s mvn:org.apache.camel.example/camel-example-ehcache-blueprint/${project.version}

And you can see the application running by tailing the logs:

log:tail

And you can use ctrl+c to stop tailing the log.

There is a data REST service that supports the following operation(s):

  • GET /data/{id} - to get data with the given id from an external service

From a web browser you can access the service using the following link(s):

http://localhost:8181/camel-example-ehcache-blueprint/data/123    - to get the data with id 123

From the command shell you can use curl to access the service as shown below:

curl -X GET -H "Accept: application/json" http://localhost:8181/camel-example-ehcache-blueprint/data/123

The first time you try to get the data it will take 3 seconds as the example (pretends to) access an external data service. But then the data will be cached, so it will be quick afterward.

Configuration

This example is implemented in XML DSL in the src/main/resources/OSGI-INF/blueprint/camel-context.xml file.
