This now does two things. If the arguments and commandLineParser objects are bound, and the bean is a CommandLine object then try to actually instantiate the command line from the Options object in the context, using the bound arguments and parser If this isn't the case and the bean has at least one method with the WireOption annotation then attempt to wire into that setter the value from the named command line option

Specified by:

postProcessBeforeInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

Throws:

org.springframework.beans.BeansException
