Spel Implicit Map [SPR-9472]

[spring-projects-issues]

Ben Hubbard opened SPR-9472 and commented

It doesn't appear possible to define an implicit map using spel. It would be nice to have a map syntax similar to groovy but using the curly braces like spel already uses for implicit lists. Something like this:

{'key1': 'value1', 'key2': 'value2'}
or
{key1: 'value1', key2: 'value2'}

@Andy, your thoughts?

This was yet another of the features it was decided we'd take out when dropping the original copy of SpEL into Spring 3.0 (Spring .Net could do it, so we originally had it too). Many of these were going to be tackled/re-activated once the users decided they needed them. Looks like users are starting to request this so we should do it.

Thanks @Andy. Slating for the General Backlog then.

Fixed. Inline maps supported using the syntax as proposed: {key:value, key2:value2} - quoting of the keys is optional. The expression {:} indicates an empty map.
