Creating a non-String keyed Map using

[mikemoran]

I'm trying to initialise a Map which is the value of a property on an instance using the <map> element. The required Map is a Class -> Class Map i.e. both keys and values are Classes. How would I do this in the xml config?

(btw, the xml config is being read with XmlBeanFactory, if that matters)

Ta,

I haven't found any solution to this problem yet.

You cannot do that right now
Spring configuration does currently allow for string keys in maps only. However, there exists already a jira issue which requests the extension to arbitrary types. So this issue should be solved in a future release.

I'm glad someone else has found this to be a problem. FYI, the JIRA url is:
http://opensource.atlassian.com/proj...browse/SPR-392

Of course, the next question is: when is RC1 due out? ;-)

In the meantime, (and it's not the cleanest looking solution, but it will work) it would probably take you about 10 minutes to create a new factory bean based off MapFactoryBean and ListFactoryBean, which given an input list consisting of alternating keys and values, would prodouce an output map... That would get you going at least...
