Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the asciidoc in the repository: https://github.com/apache/camel/blob/master/README.md https://github.com/apache/camel/blob/master/components/readme.adoc
e.g. lets invoke the
What this does is basically create a route that looks kinda like this
When using more than one CamelContext
Using context option to apply only a certain CamelContext
See the warning above.
You can use the
The consumer above will only be created for the CamelContext that have the context id =
Using an explicit route
If you want to invoke a bean method from many different endpoints or within different complex routes in different circumstances you can just use the normal routing DSL or the Spring XML configuration file.
which will then look up in the Registry and find the bean and invoke the given bean name. (You can omit the method name and have Camel figure out the right method based on the method annotations and body type).
Use the Bean endpoint
You can always use the bean endpoint
Using a property to define the endpoint
Available as of Camel 2.11
The following annotations @Consume, @Produce, @EndpointInject, now offers a
This applies for them all
The explanation below applies for all the three annotations, eg @Consume, @Produce, and @EndpointInject
If you define the bean in Spring XML or Blueprint, then you can configure the property as follows:
This allows you to configure the bean using any standard IoC style.
Camel offers a naming convention which allows you to not have to explicit name the property.
1. Use the property name if explicit given
So in the example above, we could have defined the @Consume annotation as
Now the property is named 'service' which then would match step 3 from the algorithm, and have Camel invoke the getServiceEndpoint method.
We could also have omitted the property attribute, to make it implicit
Now Camel matches step 5, and loses the prefix on in the name, and looks for 'service' as the property. And because there is a getServiceEndpoint method, Camel will use that.
Which approach to use?
Using the @Consume annotations are simpler when you are creating a simple route with a single well defined input URI.
However if you require more complex routes or the same bean method needs to be invoked from many places then please use the routing DSL as shown above.
