Method Detail

postProcessBeforeInitialization

default 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

default 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

setEnabled

default void setEnabled(boolean enabled)

Can be used to turn off bean post processing. Be careful to turn this off, as this means that beans that use Camel annotations such as EndpointInject, ProducerTemplate, Produce, Consume etc will not be injected and in use. Turning this off should only be done if you are sure you do not use any of these Camel features.

isEnabled

default boolean isEnabled()

setUnbindEnabled

default void setUnbindEnabled(boolean unbindEnabled)

isUnbindEnabled

default boolean isUnbindEnabled()

Can be used to unbind any existing beans before binding a bean to the registry. Be careful to enable this, as this will unbind all beans with the given id. This is used in special use-cases such as reloading of Camel routes which triggered updating beans that have their implementation re-compiled and re-loaded.

addCamelBeanPostProjectInjector

default void addCamelBeanPostProjectInjector(CamelBeanPostProcessorInjector injector)

Adds a custom bean post injector

Parameters:

injector - the custom injector
