How to get HashMap from JSON string?

Question

Java

Hello. There is a JSON string like:

{ 
    "data" : 
    { 
        "field1" : "value1", 
        "field2" : "value2"
    }
}

How to get a HashMap (of type field : value) from it using only Google's GSON library?
Thank you very much in advance for your reply.
