Creating multiple bean instances of a class with different property values in spring configuration

Question

I am creating multiple bean instances of a class with different property values in spring configuration. For example:

<bean id="myBeanA" class="MyClass">
  <property name="identifier" value="A"/>
</bean>

<bean id="myBeanY" class="MyClass">
  <property name="identifier" value="B"/>
</bean>

I am new to Spring framework and I am just curious to know the pros and cons to doing this.

Why has your second bean an other class name? At now you create 2 beans with different classes ;-) — Christian St., Nov 28 '13 at 11:25

of course you can (as you already show - ignoring typo). Pros/Cons? None, you just do it if it make sense for you...

<bean id="primaryService" class="MyService">
  <property name="url" value="http://domain1/"/>
</bean>

<bean id="premiumService" class="MyService">
  <property name="url" value="http://domain2/"/>
</bean>

E.g. you can have two instances of the same service type, but accessing different remote URL. You can use premiumService only for paying customers as kind of quality of service (e.g. domain2 is stronger machine)
