如何在Slick 3.1中使用不受支持的数据库

本文介绍了如何在Slick 3.1中使用不受支持的数据库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

限时删除！！

过去，我曾使用Slick访问服务器中的Vertica数据库.我最近将Slick的版本从2.0升级到了3.1.自升级以来，我遇到一个错误(下面的堆栈跟踪).该错误表明找不到光滑的驱动程序.

In the past I have used Slick to access a Vertica database in a server. I recently upgraded my version of Slick from 2.0 to 3.1. Since the upgrade, I am encountering an error (stack trace below). The error indicates that the slick driver cannot be found.

根据 Slick 3.2.1文档，其他SQL数据库可以是可以通过简化的功能集立即访问".

According to theSlick 3.2.1 docs, "Other SQL databases can be accessed right away with a reduced feature set".

我想知道的是-是否仍然可以使用slick直接支持的数据库中的其他"类型的数据库?如果可以，怎么办?

What I am wondering is - Is it still possible to use an "Other" type of database from those directly supported by slick? If so, how?

我的数据库配置是:

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}

请注意，感谢，我还尝试了以下每种方法来替换配置中的第一行:

Please note that thanks to this Stack Overflow response, I have also tried each of the following to replace the first line in the config:

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

我的sbt文件中也有

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

请注意，播放平滑使用平滑3.1.0.

Note that play-slick uses slick 3.1.0.

如果我改用:

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

然后:

推荐答案

在Slick 3.0中，不赞成使用通用的jdbc驱动程序slick.driver.JdbcDriver$(如您在源)，然后在版本 3.1 (这说明了错误)

With Slick 3.0 the generic jdbc driver slick.driver.JdbcDriver$ has been deprecated (as you can see from source) and then removed in version 3.1 (this explains the error you are seeing)

现在，使用slick 3.2，可以使用特征 slick.jdbc.JdbcProfile

By now, with slick 3.2, other databases can be supported with a custom implementation of the trait slick.jdbc.JdbcProfile
