在我的项目中，我有必要将位置数据保存在表格中，因此我创建了下表

create table if not exists public.person(
  email varchar(255) not null primary key,
  name varchar(255) not null,
  surname varchar(255) not null,
  location point
)

连同相对实体/表：

case class Person(email: String, name: String, surname: String, location: Point)

class People(tag: Tag) extends Table[Person](tag, "person") {

  def email: Rep[String] = column[String]("email")
  def name: Rep[String] = column[String]("name")
  def surname: Rep[String] = column[String]("surname")
  def location: Rep[Point] = column[Point]("location")

  def pk = primaryKey("pk", email)

  def * : ProvenShape[Person] =
    (email, name, surname, location) <> (Person.tupled, Person.unapply)

}

然后我按照这里的说明创建了我的扩展配置文件：

trait ExtendedProfile
    extends ExPostgresProfile
    with PgDateSupport
    with PgDate2Support
    with PgPostGISSupport {

  override val api: API = new API {}

  trait API
      extends super.API
      with SimpleDateTimeImplicits
      with DateTimeImplicits
      with PostGISImplicits
      with PostGISAssistants

  val plainAPI = new API
    with ByteaPlainImplicits
    with Date2DateTimePlainImplicits
    with PostGISPlainImplicits {}
}

object ExtendedProfile extends ExtendedProfile

每当我尝试在数据库中插入一个人时，我都会收到以下错误：org.postgresql.util.PSQLException: ERROR: column \"location\" is of type point but expression is of type bytea

我错过了什么吗？这是我第一次使用postgis，但是如果我直接查询数据库我可以插入点数据就好了。

尝试这个

create table if not exists public.person(
  email varchar(255) not null primary key,
  name varchar(255) not null,
  surname varchar(255) not null,
  location geometry
)

Point不是PostGIS 类型。slick-pg仅支持 PostGIS 类型。PostGIS 中的所有形状都由类型表示geometry
