To

Camel supports the Message Endpoint from the EIP patterns using the Endpoint interface.

How does an application connect to a messaging channel to send and receive messages?

Connect an application to a messaging channel using a Message Endpoint, a client of the messaging system that the application can then use to send or receive messages.

In Camel the To EIP is used for sending messages to static endpoints.

The To and ToD EIPs are the most common patterns to use in Camel routes.

Options

The To eip supports 3 options, which are listed below.

Name	Description	Default	Type
uri	Required Sets the uri of the endpoint to send to.		String
disabled	Whether to disable this EIP from the route during build time. Once an EIP has been disabled then it cannot be enabled later at runtime.	false	Boolean
pattern	Sets the optional ExchangePattern used to invoke this endpoint. Enum values: InOnly InOut		ExchangePattern
description	Sets the description of this node.		String

Different between To and ToD

The to is used for sending messages to a static endpoint. In other words to sends message only to the same endpoint.

The toD is used for sending message to a dynamic endpoint. The dynamic endpoint is evaluated on-demand by an Expression. By default, the Simple expression is used to compute the dynamic endpoint URI.

Using To

The following example route demonstrates the use of a File consumer endpoint and a JMS producer endpoint, by their URIs:

Java
XML
YAML

from("file:messages/foo")
    .to("jms:queue:foo");

<route>
    <from uri="file:messages/foo"/>
    <to uri="jms:queue:foo"/>
</route>

- from:
    uri: file:messages/foo
    steps:
      - to:
          uri: jms:queue:foo
