[Springframework-developer] Re: [Springframework-user] Velocity Tools and Spring MVC

[<jue...@we...>]

OK, I'll add an "attributes" property of type java.util.Properties and =
an "attributesMap" property of type java.util.Map to =
UrlBasedViewResolver. The first can be populated via <value> or <props>; =
the latter is meant to be populated via <map> but also allows specifying =
direct entries like <property =
name=3D"attributesMap[key1]"><value>myValue</value></property>.

"attributesCSV" doesn't make too much sense on a ViewResolver, as it's =
really just meant for view definitions in properties file (read by =
ResourceBundleViewResolver). For this reason, I'm not keen on =
introducing it on UrlBasedViewResolver.

Ok, I agree with everything above.  But here's the
problem.  I can add an attribute to a view, but if I
have 30 views in my application, and I want the same
property exposed to all 30 views, I then must define
30 view beans in my spring config (yuck!).  There is
currently no way to set attributes in a view resolver
so that the attributes are added to all views created
by that resolver.

Can you add a setAttributes(Properties prop),
setAttributesMap(Map), and a setAttributesCSV(String)
method to the
org.springframework.web.servlet.view.UrlBasedViewResolver
class?  This would then allow you to add properties to
the view resolver, so the properties are then
available in all views created by the resolver.  Since
this is a base view resolver, the functionality would
be available to all other view technologies too, so it
is a generic solution.

Thanks.
Rob
