Define the annotation bean, set the scan package.

<p>The packagePath seems to be better set in ShenyuMotanConfig,
but if so, the parameters in the configuration file can not be read,
using @Value can, probably related to the bean loading timing.

@param packagePath package path
@return  annotationBean
