Re: [Springframework-developer] no ListableWebApplicationContext?

[Rob B. <rob...@ve...>]

Dmitriy,

Yes I saw that, and i saw the ListableBeanFactory too.  But these are not
supported in the WebApplicationContext.  It doesn't appear as if you can
swap the bean factory used by the available ApplicationContexts (In spring
M2 anyways)

(ContextLoaderServlet or ContextLoaderListener) calls ContextLoader init....

ContextLoader init allows for the WebApplicationContext to be changed by
passing a parameter from web.xml - this is good.

However, there are only StaticWebApplicationContext (which should be used
for testing only - not in production as stated in the javadoc) and the
FileSystemXmlApplicationContext, ClassPathXmlApplicationContext, and
XmlWebApplicationContext all of which inherit from
AbstractXmlApplicationContext.

AbstractXmlApplicationContext only uses a XmlBeanFactory and cannot be
changed to use a different one.  Thus, there is no WebApplicationContext
that ContextLoader can use which supports ListableBeanFactory, or
JdbcBeanFactory provided in Spring.

Later
Rob
