错误是因为我注释掉了procfile试图覆盖的一些变量吗

到目前为止，我还没有接触过heroku上的数据库，我正在使用h2浏览器在网站上工作。

最有可能的是，你需要一个更新版本的postgres JDBC驱动程序。下面是一个有效的方法：

libraryDependencies ++= Seq(
  jdbc,
  cache,
  "org.postgresql" % "postgresql" % "9.4-1201-jdbc41",
  ws
)

和

这一点在报告中稍纵即逝地提到

---

另一种可能是您正在使用Slick，它最近在支持数据库URL方面进行了一次回归。它将在3.0.3中修复，但同时您必须手动将您的数据库URL转换为JDBC URL。

我已更改为上述内容，但仍然收到相同的错误。您指的是连接设置URL吗？我如何配置它？除了模型类中的几个查找器之外，我还没有定义任何数据库连接。不幸的是，HikariCP对于一些不同的问题给出了基本相同的错误。但是如果您使用上面的驱动程序，我确信它支持“测试查询”。能否尝试添加

db.default.connectionTestQuery=“SELECT TRUE”

？如果不起作用，请检查您的数据库URL是否有效（因为我看到了无效URL的错误）。您可以使用heroku pg:psql测试它

libraryDependencies ++= Seq(
  jdbc,
  cache,
  "org.postgresql" % "postgresql" % "9.4-1201-jdbc41",
  ws
)
