[Springframework-developer] proposed refactorings of XmlViewResolver

Hello,

I've implemented a XsltBeanFactory, which takes a XML doc + XSLT
stylesheet, and passes off the result to XmlBeanDefinitionReader.

As a first proof of concept, I am trying to implement a
XsltViewResolver.  I've created an optimized version of views.xml and a
stylesheet to convert it to the normal Beans DTD.

I'd like to propose a few refactorings to XmlViewResolver, to make it
easy to plug in different BeanFactories.

- - Possibly create a BeanFactoryViewResolver, with a protected method
createBeanFactory().  Subclasses can implement their own bean factory
here.  This method would be called by initBeanFactory(), which handles
all the caching operations (currently handled by XmlViewResolver's
initBeanFactory).

- - Either make location protected or add a getLocation() method.  This
would be on the XmlViewResolver, which would now subclass
BeanFactoryViewResolver.

- - a XsltViewResolver can then subclass XmlViewResolver, being able to
reuse the caching of the BeanFactory and the location property.

This is minor stuff, but making a BeanFactoryViewResolver might prove
useful as more and more BeanFactories are developed.

Thanks,
Seth
