Camel Servlet REST and OSGi Blueprint example

=============================================

Introduction

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

Build

You will need to compile this example first:

mvn install

run

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

log:tail

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

Configuration

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