Describe the feature
I want binding row with jackson-databind in vertx-sqlclient-templates with Kotlin data class
But DatabindCodec use original ObjectMapper which does not support Kotlin data class
Add some code like this, DatabindCodec can support Kotlin data class
private static void initialize() {
// automatic register module in classpath (jackson-module-kotlin, jackson-module-jsr310 ... )
mapper.findAndRegisterModules()
// mapper configuration ...
}
Use cases
By jackson-module-kotlin, create data class instance without no-args constructor
data class User(val id:Int, val firstName:String, val lastName: String): Serializable
val users:RowSet<User> = SqlTemplate
.forQuery(client, "SELECT * FROM user WHERE id=#{id}")
.mapTo(User::class.java)
.execute(mapOf("id", 1))
.await()
