Class Component

Available as of Camel 2.4

The class: component binds beans to Camel message exchanges. It works in the same way as the Bean component but instead of looking up beans from a Registry it creates the bean based on the class name.

URI format

Where className is the fully qualified class name to create and use as bean.

Options

Name

Type

Default

Description

method

String

null

The method name that bean will be invoked. If not provided, Camel will try to pick the method itself. In case of ambiguity an exception is thrown. See Bean Binding for more details.

multiParameterArray

boolean

false

How to treat the parameters which are passed from the message body; if it is true, the In message body should be an array of parameters.

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

Using

You simply use the class component just as the Bean component but by specifying the fully qualified classname instead.
For example to use the MyFooBean you have to do as follows:

You can also specify which method to invoke on the MyFooBean, for example hello:

Setting properties on the created instance

In the endpoint uri you can specify properties to set on the created instance, for example if it has a setPrefix method:

And you can also use the # syntax to refer to properties to be looked up in the Registry.

Which will lookup a bean from the Registry with the id foo and invoke the setCool method on the created instance of the MyPrefixBean class.
