AbstractFactoryBean should support strongly-typed collection (Java5+ only) [SPR-3049]

[spring-projects-issues]

Alfons Spiegelhauer opened SPR-3049 and commented

The collection classes derived from AbstractFactoryBean must support generic types.
Otherwise the result will be incorrect.

Sample:

public class NamedUrlMap extends HashMap<String, java.net.URL> {
}

application-context:
<util:map id="namedUrlRegistry" map-class="NamedUrlMap ">
<entry key="pechorin" value="classpath:a.xsd"/>
<entry key="raskolnikov" value="classpath:b/c.xsd"/>
</util:map>

After bean creation the type of the value elements is String and not URL

Thanks for pointing this out! This only really affects collection classes that declare a generic superclass or interface, hence it hasn't been noticed yet. Usually we only find out about a generic element type declared in a method or constructor parameter...

I've added such support to List/Set/MapFactoryBean.
