Question

我正在尝试使用 MySql 遵循 slick2 示例。但是，当尝试连接到数据库时，我收到结束异常

import scala.slick.driver.MySQLDriver.simple._
import slickTest.DB.SuppliersEntity

object slickTestDB {

  def main(args: Array[String]) {
    println("CreateDb!")
    val schemaName = "slickTest"
    val conn_str = "jdbc:mysql://localhost:3306/" + schemaName
    val database = Database.forURL(conn_str,user="",password="",driver="com.mysql.jdbc.Driver")
  }
}

您可能需要将 MySQL 连接器库添加为项目中的依赖项。

libraryDependencies += "mysql" % "mysql-connector-java" % "latest.release"
