Play 2框架中的几个数据源带有光滑

Question

如何使用Play 2.5.x Framework在Slick中配置和使用多个数据源？ 例如，一个数据源应为MySQL，另一个PostgreSQL。

  slick.dbs.default.driver = "utils.db.TetraoPostgresProfile$"
  slick.dbs.default.db.driver = "org.postgresql.Driver"
  slick.dbs.default.db.url = "jdbc:postgresql://localhost:5432/templatesite_db"
  slick.dbs.default.db.user = "user"
  slick.dbs.default.db.password = "pass"

  slick.dbs.secondary.driver = "slick.jdbc.MySQLProfile$"
  slick.dbs.secondary.db.driver = "com.mysql.jdbc.Driver"
  slick.dbs.secondary.db.url = "jdbc:mysql://localhost:3306/dbName"
  slick.dbs.secondary.db.user = "root"
  slick.dbs.secondary.db.password = "pass"

Answer 1

这在ScalaDatabase文档页面中直接解决：

// inject "orders" database instead of "default"
class ScalaInjectNamed @Inject()(
  @NamedDatabase("orders") db: Database) extends Controller {
  // do whatever you need with the db
}
