Question

我可以使用play的default.db连接：

db.default.driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
db.default.url="jdbc:sqlserver://my_host.database.windows.net:1433;database=my_db;"
db.default.username="username"
db.default.password="password"

但是当我尝试使用Slick时：

slick.dbs.default {
  driver = "com.typesafe.slick.driver.ms.SQLServerDriver$"
  db {
    driver    = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
    url       = "jdbc:sqlserver://my_host.database.windows.net:1433;database=my_db;"
    user      = "username"
    password  = "password"
  }
}

我明白了：

ProvisionException: Unable to provision, see the following errors:

1) Error injecting constructor, java.lang.NoClassDefFoundError: slick/profile/RelationalProfile$SimpleQL

指向我的DAO：

import play.api.db.slick.DatabaseConfigProvider

class UsersDAO @Inject() (override protected val dbConfigProvider: DatabaseConfigProvider) extends Tables(dbConfigProvider) {   // <---- This line
    ...
}

这是我的Tables.scala文件：

import models.User
import play.api.db.slick.{DatabaseConfigProvider, HasDatabaseConfigProvider}
import slick.driver.JdbcProfile

class Tables @Inject() (protected val dbConfigProvider: DatabaseConfigProvider) extends HasDatabaseConfigProvider[JdbcProfile] {

    import driver.api._

    protected val users = TableQuery[Users]
    protected class Users(tag: Tag) extends Table[User](tag, "users") {
        def id = column[String]("id", O.PrimaryKey)
        def firstName = column[String]("first_name")
        def lastName = column[String]("last_name")

        def * = (id, firstName, lastName) <> ((User.apply _).tupled, User.unapply _)
    }
}

以下是我build.sbt文件中的相关行：

libraryDependencies ++= Seq(
    ...
    "com.typesafe.play" % "play-slick_2.11" % "2.0.2",
    "com.typesafe.slick" %% "slick-extensions" % "3.0.0",
    ...
)

resolvers += "Typesafe Releases" at "http://repo.typesafe.com/typesafe/maven-releases/"

我无法找到有关SimpleQL的任何内容以及运行时遗漏的原因。

Answer 1

play-slick 2.0.2使用光滑的3.1.0，因此您必须在光滑扩展中匹配此版本：

libraryDependencies ++= Seq(
    ...
    "com.typesafe.play" % "play-slick_2.11" % "2.0.2",
    "com.typesafe.slick" %% "slick-extensions" % "3.1.0",
    ...
)

NoClassDefFoundError：slick / profile / RelationalProfile $ SimpleQL
