Direct Component

The direct: component provides direct, synchronous invocation of any consumers when a producer sends a message exchange. This endpoint can be used to connect existing routes in the same camel context.

Asynchronous

The SEDA component provides asynchronous invocation of any consumers when a producer sends a message exchange.

Connection to other camel contexts

The VM component provides connections between Camel contexts as long they run in the same JVM.

URI format

Where someName can be any string that uniquely identifies the endpoint.

Options

Name

Default Value

Description

allowMultipleConsumers

true

@deprecated

If set to false, then when a second consumer is started on the endpoint, an IllegalStateException is thrown.

Will be removed in Camel 2.1: Direct endpoint does not support multiple consumers.

block

false

Camel 2.11.1: If sending a message to a direct endpoint which has no active consumer, the producer will block for timeout milliseconds waiting for a consumer to become active.

timeout

30000

Camel 2.11.1: The timeout value, in milliseconds, to block, when enabled, for an active consumer.

failIfNoConsumers

true

Camel 2.16.0: Indicates whether the producer should fail by throwing an exception when sending to a direct endpoint with no active consumers.

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

 

Samples

In the route below we use the direct component to link the two routes together:

And the sample using spring DSL:

See also samples from the SEDA component, how they can be used together.
