I'm trying to convert a json string to a list of objects in java.

code:

List<StopEta> list = mapper.readValue(string, new TypeReference<List<Pairs>>(){});

error:

Can not deserialize instance of java.util.ArrayList out of START_OBJECT token

string equals to:

{"pairs":[{"pair1":2,"pair2":2},{"pair1":1,"pair2":1}]}
