Question

我正在尝试使用MySql来关注slick2示例。但是当我尝试连接到数据库时，我得到了结束异常

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")
  }
}

获得此异常

您可能需要在项目中添加MySQL Connector库作为依赖项。

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