Chris Beams 48836e2ebb Allow parameters in FactoryBean-returning @Bean methods Prior to this change, an assumption was made in AbstractAutowireCapableBeanFactory that any factory-method would have zero parameters. This may not be the case in @Bean methods. We now look for the factory-method by name in a more flexible fashion that accomodates the possibility of method parameters. There remains at least one edge cases here where things could still fail, for example a @Configuration class could have two FactoryBean-returning methods of the same name, but each with different generic FactoryBean types and different parameter lists. In this case, the implementation may infer and return the wrong object type, as it currently returns the first match for the given factory-method name. The complexity cost of ensuring that this never happens is not likely worth the trouble given the very low likelihood of such an arrangement. Issue: SPR-8762	14 years ago

Prior to this change, an assumption was made in
AbstractAutowireCapableBeanFactory that any factory-method would have
zero parameters.  This may not be the case in @Bean methods.

We now look for the factory-method by name in a more flexible fashion
that accomodates the possibility of method parameters.

for example a @Configuration class could have two FactoryBean-returning
methods of the same name, but each with different generic FactoryBean
types and different parameter lists. In this case, the implementation
may infer and return the wrong object type, as it currently returns
the first match for the given factory-method name.  The complexity cost
