SQL Example

SQL Example

Available as of Camel 2.11

This example is located in the examples/camel-example-sql directory of the Camel distribution.
There is a README.txt file with instructions how to run it.

If you use maven then you can easily compile and install the example from the command line:

mvn install

About

This example shows how to exchange data using a shared database table.

The example has two Camel routes. The first route insert new data into the table, triggered by a timer to run every 5th second.
The second route pickup the newly inserted rows from the table, process the row(s), and mark the row(s) as processed when done; to avoid picking up the same rows again.

Implementation

In the camel-context.xml file in the src/main/resources/META-INF/spring folder we have the Spring XML file to setup and configure the database, as well the CamelContext.

And then in the same file we setup our Camel application. At first we have a orderBean that we use in the routes to generate new orders and process orders as well.

Notice how we have externalized the SQL queries, and use Camels property placeholder to refer to the sql.properties file.

Running the example

This example can be run from the command line

mvn camel:run

Press ctrl + c to stop the example.

Running the example in OSGi such as Apache Karaf / ServiceMix

From Apache Karaf / ServiceMix shell you can install this example. You would need to install Camel first in Apache Karaf.
Camel is installed out of the box in Apache ServiceMix.

features:install camel-example-sql

When the example is running in Karaf / ServiceMix you can see in the log when it processes the orders, using

log:tail
