<property name="song" value="Jingle Bells" />

<property name="instrument" ref="saxophone" />


As illustrated here, mixing automatic and explicit wiring is also a great way to deal

with ambiguous autowiring that may occur when autowiring using byType. There

may be several beans in the Spring context that implement Instrument. To keep

Spring from throwing an exception due to the ambiguity of several Instruments

to choose from, we can explicitly wire the instrument property, effectively overriding
