Class DefaultCamelBeanPostProcessor

java.lang.Object
  org.apache.camel.impl.DefaultCamelBeanPostProcessor

public class DefaultCamelBeanPostProcessor
extends Object

A bean post processor which implements the Bean Integration features in Camel. Features such as the Bean Injection of objects like Endpoint and ProducerTemplate together with support for POJO Consuming via the Consume annotation along with POJO Producing via the Produce annotation along with other annotations such as DynamicRouter for creating a Dynamic router via annotations. RecipientList for creating a Recipient List router via annotations. RoutingSlip for creating a Routing Slip router via annotations.

Components such as camel-spring, and camel-blueprint can leverage this post processor to hook in Camel bean post processing into their bean processing framework.

Method Detail

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                              String beanName)
                                       throws Exception

Apply this post processor to the given new bean instance before any bean initialization callbacks (like afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

Parameters:

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

Throws:

Exception - is thrown if error post processing bean

postProcessAfterInitialization

public Object postProcessAfterInitialization(Object bean,
                                             String beanName)
                                      throws Exception

Apply this post processor to the given new bean instance after any bean initialization callbacks (like afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

Parameters:

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

Throws:

Exception - is thrown if error post processing bean

getOrLookupCamelContext
