HikariCP是光面3.0.0中的默认连接池

我已经在example中定义了驱动程序类：

trait MyPostgresDriver extends ExPostgresDriver with PgArraySupport
  with PgEnumSupport
  with PgRangeSupport
  with PgHStoreSupport
  with PgSearchSupport{

  override val api = new MyAPI {}

  //////
  trait MyAPI extends API
  with ArrayImplicits
  with RangeImplicits
  with HStoreImplicits
  with SearchImplicits
  with SearchAssistants

}

object MyPostgresDriver extends MyPostgresDriver

我的数据库配置非常简单[以下类型安全配置的摘录]：

slick.dbs.default {

  driver="com.github.tminglei.MyPostgresDriver$"

  db {
    driver="org.postgresql.Driver"

    url="jdbc:postgresql://hostname:port/dbname"
    user=user
    password="pass"
  }
}

它似乎不应该工作,但……

我应该以某种方式改变我的司机课程吗？还有别的吗？

注意：在我正在使用的stacktrace中可以看到

> Java 1.7.0_79
> Scala 2.11.7
> akka 2.3.11(我分享了光滑和akka的配置实例)
>光滑的3.0.0
> HikariCP-java6 2.3.8
> tminglei的slick-pg_core 0.9.0

最后,通过Class.class中的jdk代码进行调试时(反编译的第143行)

Constructor tmpConstructor1 = this.cachedConstructor;

我得到以下(toString’ed)值(如intellij所示)：

private com.github.tminglei.MyPostgresDriver$()

这可能是问题的原因吗？如果是这样我该如何解决？

编辑

我已经用库存PostgresDriver替换了自定义驱动程序配置,如下所示：

slick.dbs.default {

  driver="slick.driver.PostgresDriver$"

  db {
    driver="org.postgresql.Driver"

    url="jdbc:postgresql://hostname:port/dbname"
    user=user
    password="pass"
  }
}

错误是一样的：

akka.actor.ActorInitializationException: exception during creation
    ...
Caused by: java.lang.RuntimeException: driverClassName specified class 'slick.driver.PostgresDriver$' could not be loaded
    ... 
Caused by: java.lang.IllegalAccessException: Class com.zaxxer.hikari.AbstractHikariConfig can not access a member of class slick.driver.PostgresDriver$with modifiers "private"
