BeanIO
Available as of Camel
...
2.10
...
The
...
BeanIO
...
...
...
uses
...
...
to
...
handle
...
flat
...
payloads
...
(such
...
as
...
XML,
...
CSV,
...
delimited,
...
or
...
fixed
...
length
...
formats).
...
BeanIO
...
is
...
configured
...
using
...
a
...
...
...
file
...
where
...
you
...
define
...
the
...
mapping
...
from
...
the
...
flat
...
format
...
to
...
Objects
...
(POJOs).
...
This
...
mapping
...
file
...
is
...
mandatory
...
to
...
use.

receives a message for each row.
The 2nd route is for the reverse operation, to transform a List<Employee> into a stream of CSV data.

Dependencies
To use BeanIO in your Camel routes you need to add a dependency on camel-beanio which implements this data format.
If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).
