How to use Jackson DataType: JSR310 Deser standalone?

Question

I'm in a scenario where I'm converting from type A to type B . Type A has a date field which is of type YearMonth , and type B 's date field is a String . I don't want to reinvent the wheel, so it'd be great if I could use The Jackson DataType JSR310 library for this conversion.

However, I'm quite confused how I can use the YearMonthSerializer 's public serialize method in a standalone way; same goes for YearMonthDeserializer 's public deserialize method.

serialize takes in a YearMonth (fine) alonside a JsonGenerator and SerializationProvider (what?) which I'm not sure how to retrieve, whereas derialize doesn't even have a String as an argument, just a JsonParser and DeserializationContext .

I don't want to use this library in the typical way @JsonSerialize(using = YearMonthSerializer.class) because I'm not converting an entire POJO to a JSON sting, just one YearMonth field to a String .

Based on these APIs though it almost looks like I am definitely not intended to use the library in this desired way.

Here 'sa link to the javadoc.

why not you use the @JsonSerialize(using = YearMonthSerializer.class) above the date field instead of above the class. because you don't want to use it for the entire POJO
