Support for Java 8 date/time types.

[itanor]

Hi, at the moment the library is not supporting Java 8 date/time types like LocalDateTime?

I saw in the source code that has no writer for LocalDateTime type, eg.
Is there a way to extend some class or other way to make it work for Java 8 types?

I am using jackson-datatype-jsr310 in Spring Boot with serializer and deserializer and works fine. But when I use code like that

json.use(JsonView.with(obj).onClass(Obj.class, match().exclude("foo"))).returnValue()

it's not respecting the serializer of the annotation. I have this code:

@JsonSerialize(using = CustomLocalDateTimeSerializer.class)
private LocalDateTime someDate;

CustomLocalDateTimeSerializer serialize to milliseconds, but the code of CustomLocalDateTimeSerializer it's not invoked when I use the library.

The result in JSON for LocalDateTime is

someDate":{
  "date":{
    "year":2016,
    "month":7,
    "day":22
  },
  "time":{
    "hour":20,
    "minute":16,
    "second":27,
    "nano":881000000
  }
}

Thanks, and great library...

I need a custom serializer on Date fields.
https://github.com/aabeling/json-view provides a unit test and a workaround.
But it is really only a dirty workaround.
As far as I can see almost all annotations like JsonSerialize, JsonDeserialize, JsonFormat on methods or fields are ignored when the JsonView is used.
That is really a drawback of this library.

Update: due to this drawback we implemented our own solution (inspired by json-view) which is explained in http://aabeling.github.io/blog/How-to-control-json-responses-with-jackson-on-a-per-request-basis-to-implement-an-expand-mechanism

I added this in for the 0.14 release. It still depends on the presence of the appropriate Jackson modules, but that's not a big deal (I hope).
