Re: [Springframework-developer] In BeanFactory, ref to another bean's properties, not to the other bean directly

[Colin S. <col...@ex...>]

How about this for constructing beans via a static factory method

<bean id="whatever">
  <static-factory method="a.b.c.d.MyClass.myFactory"/>
</bean>

which would cover static methods with no args. A second step would be:

<bean id="whatever">
  <static-factory method="a.b.c.d.MyClass.myFactory">
    <arg>  ... </arg>
    <arg>  ... </arg>
  </static-factory>
</bean>

where arg is basically the same thing as constructor-arg in the current 
dtd...
