Mustache
Available as of Camel
...
2.12
...
The
...
mustache:
...
component
...
allows
...
for
...
processing
...
a
...
message
...
using
...
a
...
...
template.
...
This
...
can
...
be
...
ideal
...
when
...
using
...
...
to
...
generate
...
responses
...
for
...
requests.
...
Maven
...
users
...
will
...
need
...
to
...
add
...
the
...
following
...
dependency
...
to
...
their
...
pom.xml
...
for
...
this
...
component:
| Code Block | ||||
|---|---|---|---|---|

{code:xml}
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-mustache</artifactId>
<version>x.x.x</version> <!-- use the same version as your Camel core version -->
</dependency>
|
URI format
| Code Block |

{code} h3. URI format {code} mustache:templateName[?options] {code} Where *templateName* is the |
Where templateName is the classpath-local
...
URI

Mustache
...
Context
...
Camel
...
will
...
provide
...
exchange
...
information
...
in
...
the
...
Mustache
...
context
...
(just
...
a
...
Map
...
).
...
The
...
Exchange
...
is
...
transferred
...
as:
| Wiki Markup |
|---|
{div:class=confluenceTableSmall} || key || value || | {{exchange}} | The {{Exchange}} itself. | | {{exchange.properties}} | The {{Exchange}} properties. | | {{headers}} | The headers of the In message. | | {{camelContext}} | The Camel Context. | | {{request}} | The In message. | | {{body}} | The In message body. | | {{response}} | The Out message (only for InOut message exchange pattern). | {div} h3. |
Dynamic
...
templates
...
Camel
...
provides
...
two
...
headers
...
by
...
which
...
you
...
can
...
define
...
a
...
different
...
resource
...
location
...
for
...
a
...
template
...
or
...
the
...
template
...
content
...
itself.
...
If
...
any
...
of
...
these
...
headers
...
is
...
set
...
then
...
Camel
...
uses
...
this
...
over
...
the
...
endpoint
...
configured
...
resource.
...
This
...
allows
...
you
...
to
...
provide
...
a
...
dynamic
...
template
...
at
...
runtime.
| Wiki Markup |
|---|
{div:class=confluenceTableSmall} || Header || Type || Description || Support Version || | MustacheConstants.MUSTACHE_RESOURCE_URI | String | A URI for the template resource to use instead of the endpoint configured. | | | MustacheConstants.MUSTACHE_TEMPLATE | String | The template to use instead of the endpoint configured. | | {div} h3. Samples For example you could use something like: {code} |
Samples
For example you could use something like:
| Code Block |
|---|
from("activemq:My.Queue").
to("mustache:com/acme/MyResponse.mustache");
{code}
|
To
...
use
...
a
...
Mustache
...
template
...
to
...
formulate
...
a
...
response
...
for
...
a
...
message
...
for
...
InOut
...
message
...
exchanges
...
(where
...
there
...
is
...
a
...
JMSReplyTo
...
header).
...
If
...
you
...
want
...
to
...
use
...
InOnly
...
and
...
consume
...
the
...
message
...
and
...
send
...
it
...
to
...
another
...
destination
...
you
...
could
...
use:
| Code Block |
|---|
} from("activemq:My.Queue"). to("mustache:com/acme/MyResponse.mustache"). to("activemq:Another.Queue"); {code} |
It's
...
possible
...
to
...
specify
...
what
...
template
...
the
...
component
...
should
...
use
...
dynamically
...
via
...
a
...
header,
...
so
...
for
...
example:
| Code Block |
|---|
}
from("direct:in").
setHeader(MustacheConstants.MUSTACHE_RESOURCE_URI).constant("path/to/my/template.mustache").
to("mustache:dummy");
