DefaultColumnMapper

class DefaultColumnMapper[T] extends ColumnMapper[T]

A ColumnMapper that assumes camel case naming convention for property accessors and constructor names and underscore naming convention for column names.

Example mapping:

case class User(
login: String,         // mapped to "login" column
emailAddress: String   // mapped to "email_address" column
emailAddress2: String  // mapped to "email_address_2" column
)

Additionally, it is possible to name columns exactly the same as property names (case-sensitive):

case class TaxPayer(
TIN: String            // mapped to "TIN" column
)
