How can I use GSON to parse and place into a list of objects?

Question

I have a domain object Foo, and I want to parse some JSON such as

[
    {"prop": "val"},
    {"prop": "val2"},
]

You need to use a TypeToken to correctly express the type. Class is not sufficient in this case, because of the interaction with the generic type.

Type listType = new TypeToken>(){}.getType();
List projects = (List) gson.fromJson(response, listType);
