Camel Servlet REST and OSGi Blueprint example


This example shows how to use Servlet REST to define REST endpoints in Camel routes using the Rest DSL


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/ServiceMix with:

feature:install camel-servlet
feature:install camel-jackson
feature:install war

Then you can install the Camel example:

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

And you can see the application running by tailing the logs


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

There is a user REST service that supports the following operations

  • GET /user/{id} - to view a user with the given id
  • GET /user/final - to view all users
  • PUT /user - to update/create an user

The view operations are HTTP GET, and update is using HTTP PUT.

From a web browser you can access the first two services using the following links

  http://localhost:8181/camel-example-servlet-rest-blueprint/rest/user/123    - to view the user with id 123
  http://localhost:8181/camel-example-servlet-rest-blueprint/rest/user/findAll   - to list all users

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-servlet-rest-blueprint/rest/user/123
curl -X GET -H "Accept: application/json" http://localhost:8181/camel-example-servlet-rest-blueprint/rest/user/findAll
curl -X PUT -d "{ \"id\": 666, \"name\": \"The devil\"}" -H "Accept: application/json" http://localhost:8181/camel-example-servlet-rest-blueprint/rest/user


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