RSS

Since Camel 2.1

The RSS component ships with an RSS dataformat that can be used to convert between String (as XML) and ROME RSS model objects.

  • marshal = from ROME SyndFeed to XML String

  • unmarshal = from XML String to ROME SyndFeed

A route using this would look something like this:

The purpose of this feature is to make it possible to use Camel’s lovely built-in expressions for manipulating RSS messages. As shown below, an XPath expression can be used to filter the RSS message:

Query parameters

If the URL for the RSS feed uses query parameters, this component will understand them as well, for example if the feed uses alt=rss, then you can for example do from("rss:http://someserver.com/feeds/posts/default?alt=rss&splitEntries=false&delay=1000").to("bean:rss");

Options

The RSS dataformat supports 1 options, which are listed below.

Name Default Java Type Description

contentTypeHeader

false

Boolean

Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON etc.

Spring Boot Auto-Configuration

When using rss with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

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

The component supports 5 options, which are listed below.

Name Description Default Type

camel.component.rss.basic-property-binding

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

Boolean

camel.component.rss.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.rss.enabled

Whether to enable auto configuration of the rss component. This is enabled by default.

Boolean

camel.dataformat.rss.content-type-header

Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON etc.

false

Boolean

camel.dataformat.rss.enabled
