This example shows how to use camel-ehcache
to cache messages in a Camel route.
You will need to compile this example first:
mvn install
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):
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.
This example is implemented in XML DSL in the src/main/resources/OSGI-INF/blueprint/camel-context.xml
file.
