If the attribute value to be set for bean is another bean instance in the container, use<Ref.../>Element. When using the ref element, you can specify the following two attributes:

① Bean:Reference the ID attribute values of other bean instances that are not in the same xml configuration file.

② Local:Reference the ID attribute values of other bean instances in the same xml configuration file.

<Bean id = "steelaxe" class = "com. bean. steelaxe "/> <bean id =" Chinese "class =" com. bean. chinese "> <property name =" Axe "> <ref local =" steelaxe "/> </property> </bean>

<Bean id = "steelaxe" class = "com. bean. steelaxe "/> <bean id =" Chinese "class =" com. bean. chinese "> <property name =" Axe "ref =" steelaxe "/> </bean>
