| == 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. |
