Play 2.6 的 conf 文件中 Hikari、Quill 和 Postgres 之间的冲突
Conflict between Hikari, Quill, and Postgres in the conf file for Play 2.6
当我 运行 我的 Play 应用程序（这似乎是我现在生活中的故事）时，我遇到了一个 st运行ge 错误。前几天，我 运行 进入 ，解决了这个问题，能够 运行 演变并创建表格，然后 运行 进入以下内容：
java.lang.RuntimeException: Property driver does not exist on target class com.zaxxer.hikari.HikariConfig
这是我当前 application.conf 的相关部分：
db.default {
dataSourceClassName = org.postgresql.ds.PGSimpleDataSource
url = "jdbc:postgresql://localhost:5432/app-users?user=root&password=root"
driver = org.postgresql.Driver
username = root
password = root
databaseName = app-users
portNumber = 5432
serverName = localhost
connectionTimeout = 30000
}
我确实 some digging and found that Hikari expects driverClassName (along with a few other differences). The Hikari docs and the Quill docs 说过像这样的东西应该在 application.conf:
dataSourceClassName=org.postgresql.ds.PGSimpleDataSource
dataSource.user=root
dataSource.password=root
dataSource.databaseName=app-users
dataSource.portNumber=5432
dataSource.serverName=localhost
然而，当我拥有它时，进化不会 运行。他们只会 运行 当我像现在这样拥有它时。由于演变是 运行ning，它似乎正在连接到数据库。那么为什么我会收到一条消息说它不能呢？有没有办法让我为 Hikari 和 Postgres/Quill 设置单独的数据库配置？

有什么可能导致这种情况的想法吗？或者我缺少什么？
使用：

- 羽毛笔 2.3.2
- 播放 2.6.6
- Postgres JDBC 驱动程序 42.2.1
- PostgreSQL 10.2

不幸的是，Hikari 和 Play 并没有使用完全相同的命名约定来设置它们的数据源，例如 Quill 期望一个空 dataSourceClassName 但 Play 想要它的格式如 db.default.dataSourceClassName。据我所知，没有办法修改你的配置来满足它们，你可能不想这样做，原因如下：
Play 实际上使用 Hikari 作为它的池数据源，所以当您通过 db.default 创建数据库时，您实际上已经在创建一个池数据源。当您使用裸配置调用 PostgresJdbcContext 时，您实际上是在要求 Quill 创建一个完全独立的连接池。不确定这是否是您想要的，但我假设您只需要一个连接池。
Quill 实际上公开了一个接受 DataSource 的构造函数，因此您可以做的是使用 Play 创建的 Database 并将其直接传递给 Quill：
import io.getquill.{PostgresJdbcContext, SnakeCase}
import com.zaxxer.hikari.HikariDataSource
import play.api.db.Database
package object db {
class DBContext(db: Database) extends PostgresJdbcContext(SnakeCase, db.dataSource.asInstanceOf[HikariDataSource])
}
这应该可以解决您的问题，并且只会创建一个连接池。您可以通过依赖注入获得 Database 对象。
你必须在这里做一个丑陋的 asInstanceOf 因为 PostgresJdbcContext 需要 dataSource 来实现 Closeable，而 DataSource class 不执行。我已经 运行 遇到了类似的问题，但还没有找到更优雅的方法。
