使用带有Slick 2代码生成器的PostgreSQL JSON类型

我在我的 Scala / Play应用程序中使用 Slick 2 code generator来生成PostgreSQL数据库的表类.有些字段是JSON类型,它们由生成器转换为String.我想知道我是否能以某种方式使用 slick-pg plugin使发生器识别Postgres JSON类型？

我试图直接在Build.scala中扩展slick.driver.PostgresDriver：

import slick.driver.PostgresDriver
import com.github.tminglei.slickpg._

trait MyPostgresDriver extends PostgresDriver
                          with PgArraySupport
                          with PgDateSupport
                          with PgRangeSupport
                          with PgHStoreSupport
                          with PgPlayJsonSupport
                          with PgSearchSupport
                          with PgPostGISSupport {

  override val Implicit = new ImplicitsPlus {}
  override val simple = new SimpleQLPlus {}

  trait ImplicitsPlus extends Implicits
                        with ArrayImplicits
                        with DateTimeImplicits
                        with RangeImplicits
                        with HStoreImplicits
                        with JsonImplicits
                        with SearchImplicits
                        with PostGISImplicits

  trait SimpleQLPlus extends SimpleQL
                        with ImplicitsPlus
                        with SearchAssistants
                        with PostGISAssistants
}

object MyPostgresDriver extends MyPostgresDriver

但我不知道如何使用代码生成器例程而不是标准驱动程序：

SourceCodeGenerator.main(
    Array(
        "scala.slick.driver.PostgresDriver",//how do I use MyPostgresDriver here?
        "org.postgresql.Driver","jdbc:postgresql://localhost:5432/db?user=root&password=root","app","db"
    )
)
