RE: [Springframework-developer] PropertyPathFactoryBean

[Rod J. <ro...@in...>]

Have to say that this looks to me like it's making a case for an =
expression
language instead of a FactoryBean.=20

A similar requirement that would also be well addressed by =
OGNL/whatever:
evaluating a constant. E.g. an AutowireCapableBeanFactory constant, =
which I
recently had to configure via a property. It would be nice to be able to =
do
that easily.

Good stuff. It overlaps of course with the mythical OGNL or expression
support which keeps getting pushed back, but in the meantime provides =
some
of the benefits for pretty little extra code...
