    [[MVELComponent-MVELComponent]]
    MVEL Component
    ~~~~~~~~~~~~~~

    *Available as of Camel 2.12*

    The *mvel:* component allows you to process a message using an
    http://mvel.codehaus.org/[MVEL] template. This can be ideal when using
    link:templating.html[Templating] to generate responses for requests.

    Maven users will need to add the following dependency to their `pom.xml`
    for this component:

    [source,xml]
    ------------------------------------------------------------
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-mvel</artifactId>
        <version>x.x.x</version>
        <!-- use the same version as your Camel core version -->
    </dependency>
    ------------------------------------------------------------

    [[MVELComponent-URIformat]]
    URI format
    ^^^^^^^^^^

    [source,java]
    ---------------------------
    mvel:templateName[?options]
    ---------------------------

    Where *templateName* is the classpath-local URI of the template to
    invoke; or the complete URL of the remote template (eg:
    file://folder/myfile.mvel[file://folder/myfile.mvel]).

    You can append query options to the URI in the following format,
    `?option=value&option=value&...`

    [[MVELComponent-Options]]
    Options
    ^^^^^^^


    // component options: START
    The MVEL component has no options.
    // component options: END




    // endpoint options: START
    The MVEL component supports 4 endpoint options which are listed below:

    {% raw %}
    [width="100%",cols="2,1,1m,1m,5",options="header"]
    |=======================================================================
    | Name | Group | Default | Java Type | Description
    | resourceUri | producer |  | String | *Required* Path to the resource or a reference to lookup a bean in the Registry to use as the resource
    | contentCache | producer | false | boolean | Sets whether to use resource content cache or not
    | encoding | producer |  | String | Character encoding of the resource content.
    | synchronous | advanced | false | boolean | Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported).
    |=======================================================================
    {% endraw %}
    // endpoint options: END



    [[MVELComponent-MessageHeaders]]
    Message Headers
    ^^^^^^^^^^^^^^^

    The mvel component sets a couple headers on the message.

    [width="100%",cols="10%,90%",options="header",]
    |=======================================================================
    |Header |Description

    |`CamelMvelResourceUri` |The *templateName* as a `String` object.
    |=======================================================================

    [[MVELComponent-MVELContext]]
    MVEL Context
    ^^^^^^^^^^^^

    Camel will provide exchange information in the MVEL context (just a
    `Map`). The `Exchange` is transfered as:

    [width="100%",cols="10%,90%",options="header",]
    |=======================================================================
    |key |value

    |`exchange` |The `Exchange` itself.

    |`exchange.properties` |The `Exchange` properties.

    |`headers` |The headers of the In message.

    |`camelContext` |The Camel Context intance.

    |`request` |The In message.

    |`in` |The In message.

    |`body` |The In message body.

    |`out` |The Out message (only for InOut message exchange pattern).

    |`response` |The Out message (only for InOut message exchange pattern).
    |=======================================================================

    [[MVELComponent-Hotreloading]]
    Hot reloading
    ^^^^^^^^^^^^^

    The mvel template resource is, by default, hot reloadable for both file
    and classpath resources (expanded jar). If you set `contentCache=true`,
    Camel will only load the resource once, and thus hot reloading is not
    possible. This scenario can be used in production, when the resource
    never changes.

    [[MVELComponent-Dynamictemplates]]
    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.

    [width="100%",cols="10%,10%,80%",options="header",]
    |=======================================================================
    |Header |Type |Description

    |CamelMvelResourceUri |String |A URI for the template resource to use instead of the endpoint
    configured.

    |CamelMvelTemplate |String |The template to use instead of the endpoint configured.
    |=======================================================================

    [[MVELComponent-Samples]]
    Samples
    ^^^^^^^

    For example you could use something like

    [source,java]
    --------------------------------------
    from("activemq:My.Queue").
      to("mvel:com/acme/MyResponse.mvel");
    --------------------------------------

    To use a MVEL template to formulate a response to a message for InOut
    message exchanges (where there is a `JMSReplyTo` header).

    To specify what template the component should use dynamically via a
    header, so for example:

    [source,java]
    -------------------------------------------------------------------------
    from("direct:in").
      setHeader("CamelMvelResourceUri").constant("path/to/my/template.mvel").
      to("mvel:dummy");
    -------------------------------------------------------------------------

    To specify a template directly as a header the component should use
    dynamically via a header, so for example:

    [source,java]
    ------------------------------------------------------------------------------------------
    from("direct:in").
      setHeader("CamelMvelTemplate").constant("@{\"The result is \" + request.body * 3}\" }").
      to("velocity:dummy");
    ------------------------------------------------------------------------------------------
