kotlinlang

Hi, I am new with kotlin. Can you help me with this data mapping problem?

```ObjectMapper().apply { 
    registerKotlinModule() 
}.writeValueAsString(MyClass(...))```
You don't need `@JsonCreator` and if you want to specify names for fields explicitly for data classes you do:

```data class MyClass(
    @field:JsonProperty("changed_at")
    val changedAt: LocalDate
)```
I suggest browsing through the kotlin module: <https://github.com/FasterXML/jackson-module-kotlin>
