Undertow Component

Available as of Camel 2.16

The undertow component provides HTTP-based endpoints for consuming and producing HTTP requests. That is, the Undertow component behaves as a simple Web server.
Undertow can also be used as a http client which mean you can also use it with Camel as a producer.

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

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-undertow</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

undertow:http://hostname[:port][/resourceUri][?options]

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

Options

Message Headers

Camel uses the same message headers as the HTTP component.
From Camel 2.2, it also uses Exchange.HTTP_CHUNKED,CamelHttpChunked header to turn on or turn off the chuched encoding on the camel-undertow consumer.

Camel also populates all request.parameter and request.headers. For example, given a client request with the URL, http://myserver/myserver?orderid=123, the exchange will contain a header named orderid with the value 123.

Component Options

The UndertowComponent provides the following options:

Producer Example

The following is a basic example of how to send an HTTP request to an existing HTTP endpoint.

in Java DSL

from("direct:start").to("undertow:http://www.google.com");

or in Spring XML

<route>
    <from uri="direct:start"/>
    <to uri="undertow:http://www.google.com"/>
<route>

Consumer Example

In this sample we define a route that exposes a HTTP service at http://localhost:8080/myapp/myservice:

<route>
  <from uri="undertow:http://localhost:8080/myapp/myservice"/>
  <to uri="bean:myBean"/>
</route>
