设置一切正常但在尝试使用 Quill 时出现错误 "Failed to load data source for config"？

Question

我尝试在 IDEA 中使用 quill，设置一切正常：

1 sbt 依赖项：

libraryDependencies ++= Seq(
 "mysql" % "mysql-connector-java" % "8.0.17",
 "io.getquill" %% "quill-jdbc" % "3.7.0"
)

2 application.properties（使用我的参数）：

ctx.dataSourceClassName=com.mysql.cj.jdbc.MysqlDataSource
ctx.dataSource.url=jdbc:mysql://host/database
ctx.dataSource.user=root
ctx.dataSource.password=root
ctx.dataSource.cachePrepStmts=true
ctx.dataSource.prepStmtCacheSize=250
ctx.dataSource.prepStmtCacheSqlLimit=2048
ctx.connectionTimeout=30000

我还没有找到文件 application.properties 在 sbt 项目中的位置，但是我已经在项目的每个 floder:the top floder 中复制了它，floder /src，floder /project，所以我认为它会起作用

3 代码（使用mysql“世界”数据库）：

import io.getquill._

object A extends App{

 lazy val ctx = new MysqlJdbcContext(SnakeCase, "ctx")
 import ctx._

 case class City(id: Int,name:String,countryCode:String,district:String,population:Int)

 val q = quote {
  query[City].filter(c => c.id > 1)
 }

 ctx.run(q) 
}

但出现错误：

jdbcUrl is required.

那怎么解决呢？我觉得这个程序找不到 config.Thanks!

Answer 1

将配置属性放入 application.conf 而不是 application.properties
