如何在Slick 3.1中使用不受支持的數據庫

[英]How to use a Non Supported Database in Slick 3.1

問題描述

過去，我使用Slick訪問服務器中的Vertica數據庫。 我最近將我的Slick版本從2.0升級到3.1。 自升級以來，我遇到了一個錯誤（下面的堆棧跟蹤）。 該錯誤表示無法找到光滑的驅動程序。

根據Slick 3.2.1文檔 ，“可以使用縮減的功能集立即訪問其他SQL數據庫”。

我想知道的是 - 是否仍然可以使用光滑直接支持的“其他”類型的數據庫？ 如果是這樣，怎么樣？

我的數據庫配置是： 

slick.dbs.default.driver="slick.driver.JdbcDriver"
slick.dbs.default.db.driver="com.vertica.jdbc.Driver"
slick.dbs.default.db.url=${some.url}
slick.dbs.default.db.user=${some.user}
slick.dbs.default.db.password=${some.pw}

請注意，由於此Stack Overflow響應 ，我還嘗試了以下各項來替換配置中的第一行： 

slick.dbs.default.driver="slick.driver.JdbcDriver$"
slick.dbs.default.driver="slick.driver.JdbcDriver$class"
slick.dbs.default.driver=slick.driver.JdbcDriver

我也有我的sbt文件： 

libraryDependencies ++= Seq(
  "com.vertica" % "vertica-jdbc" % "7.0.1",
  "com.typesafe.play" %% "play-slick" % "2.0.0")

請注意，Play-slick使用光滑的3.1.0。

完整堆棧跟蹤：

如果我改為使用： 

slick.dbs.default.driver="slick.driver.JdbcDriver$"

使用Slick 3.0時，不推薦使用通用的jdbc驅動程序slick.driver.JdbcDriver$ （從源代碼中可以看到），然后在3.1版中刪除（這解釋了您看到的錯誤）

到目前為止，使用光滑的3.2，可以使用trait slick.jdbc.JdbcProfile的自定義實現來支持其他數據庫。
