custom type example

[jmisur]

Example of using Money type in response object.
I think serializing Money into 2 fields is hack anyway, which we should change. It contains hidden implicit field without possibility to change the name.
If anybody needs to serialize custom (3rd party) type into json with multiple fields, one can use custom class and map fields manually.

My opinion: If a serializer adds more than just a value, it should be nested, e.g.

{
  "balance": {
    "amount": 100.0,
    "currency": "EUR"
  }
}

This way it does not hurt that amount and currency have fixed names, because they are nested and the field can have a custom name (here: balance).

But for this PR it does not matter as only a value is written.

Yes in that case simple class with those fields is sufficient - for which existing facilities just work. I did a hacky serialization for Money because it's 3rd party, but I would rather change it in API than provide some hacky support in restdocs.
Can I merge?

If you look at the method in isolation, it's impossible to see where the 2 is comming from. How about:
int cut = javaMethodName.startsWith("get") ? "get".length() : "is".length();

LGTM, just one potential readability improvement
