play-json-naming
Custom naming convention for play-json to map snake_case json to camelCase case classes.
Releases
For Play 2.6 or later, I recommend to use play.api.libs.json.JsonNaming

Setup
libraryDependencies += "com.github.tototoshi" %% "play-json-naming" % "1.5.0"Usage
import com.github.tototoshi.play.json.JsonNaming
case class Name(firstName: String, lastName: String)
case class User(id: Int, nameData: Name)
implicit val nameFormat = JsonNaming.snakecase(Json.format[Name])
implicit val userFormat = JsonNaming.snakecase(Json.format[User])
val jsonString = """{"id":1,"name_data":{"first_name":"Toshiyuki","last_name":"Takahashi"}}"""
Json.parse(jsonString).validate[User]
Json.toJson(User(1, Name("Toshiyuki", "Takahashi")))
