我有一个Play框架应用程序，想要同时使用Slick连接到Postgres，同时使用JDBC连接到Apache Phoenix。
与Postgres的连接效果很好。但是我无法从Play连接到Phoenix。
我在一个独立的Scala应用程序中测试了与Phoenix的连接，没有Play，这很有用。
以下是独立应用程序的代码段：
import java.sql._
object TestPhoenix extends App {
val connectionString = "jdbc:phoenix:srv1,srv2,srv3,srv4:/hbase"
val request = "select * from MY_TABLE limit 10"
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver")
val conn = DriverManager.getConnection(connectionString)
val stmt = conn.prepareStatement(request)
val rs = stmt.executeQuery()
var hasNext = rs.next()
while (hasNext) {
println(rs.getBytes(1))
hasNext = rs.next()
}
}
我尝试在Play应用程序的控制器中使用相同的代码，但这不起作用。如果我尝试与Slick建立连接，它也不起作用：
class DbRequester(connectionString: String, request: String)(implicit val ec: ExecutionContext){
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver")
val db: JdbcBackend.DatabaseDef = Database.forURL(connectionString, driver="org.apache.phoenix.jdbc.PhoenixDriver")
val conn = db.source.createConnection()
val stmt = conn.prepareStatement(request)
def sendRequest() = {
stmt.executeQuery()
}
}
有一个堆栈跟踪：

此外，我尝试将jdbc依赖项添加到我的build.sbt中，由于这个原因，这也不起作用：https://www.playframework.com/documentation/2.6.x/PlaySlickFAQ#A-binding-to-play.api.db.DBApi-was-already-configured
并且没有办法与标准的Slick DatabaseConfig建立连接，因为Slick没有Apache Phoenix的配置文件。
那么，有没有办法连接凤凰城，并将Slick保留在我的项目中？
