scala使用slick查詢的全過程(使用cass class)

1.

首先導包

<dependency>
    <groupId>com.typesafe.slick</groupId>
    <artifactId>slick_2.10</artifactId>
    <version>3.1.1</version>
</dependency>
2.配置mysql application.conf

mip_common = {
  url = "jdbc:mysql://${DB.MI.HOST}:${DB.MI.PORT}/${DB.MI.DB.COMMON}"
  driver = com.mysql.jdbc.Driver
  user = "${DB.MI.USER}"
  password = "${DB.MI.PSWD}"
  connectionPool = disabled
  keepAliveConnection = true
}

3.創建class與表綁定

package com.you.model.mysql

import slick.driver.MySQLDriver.api._


object Campaign {

  //表字段對應模版
  case class CampaignModel(id: Long, version: Long, creation: String, lastModified: String, companyId: Option[Long], brand: Option[String], brandId: Option[Long]
                      , campaign: Option[String], beginDate: Option[String], endDate: Option[String], url: Option[String], removed: Int,
                      targetType: Option[String], adslotType: Option[String], deviceType: Option[String])

//表結構: 定義字段類型, * 代表結果集字段

  class CampaignTable(tag: Tag) extends Table[CampaignModel](tag, "campaign") {
    def id = column[Long]("id")

    def version = column[Long]("version")

    def creation = column[String]("creation")

    def lastModified = column[String]("last_modified")

    def companyId = column[Option[Long]]("company_id")

    def brand = column[Option[String]]("brand")

    def brandId = column[Option[Long]]("brand_id")

    def campaign = column[Option[String]]("campaign_name")

    def beginDate = column[Option[String]]("begin_date")

    def endDate = column[Option[String]]("end_date")

    def url = column[Option[String]]("url")

    def removed = column[Int]("removed")

    def targetType = column[Option[String]]("target_type")

    def adslotType = column[Option[String]]("adslot_type")

    def deviceType = column[Option[String]]("device_type")

    def * = (id, version, creation, lastModified, companyId, brand, brandId,
      campaign, beginDate, endDate, url, removed,
      targetType, adslotType, deviceType) <> (CampaignModel.tupled, CampaignModel.unapply)

  }

  //庫表實例
  val q = TableQuery[CampaignTable]
}

4.編寫dao接口(必須使用Await.result否則查不出數據)

object CampaignDao {
  def selectCampaignAndTracking(advertiseid: Long): Map[Long, CampaignAndTracking] = {
    val db = Database.forConfig("mip_common")
    val tuples: Seq[(Campaign.CampaignModel, Tracking.TrackingModel)] = Await.result(db.run(Campaign.q.join(Tracking.q)
      .on(_.id === _.campaignId)
      .filter { case (campaign, tracking) => campaign.companyId === advertiseid && campaign.removed === 0 && tracking.removed === false }
      .result), Duration.Inf)
    val value: Seq[(Long, CampaignAndTracking)] = tuples.map { case (campaign, tracking) => campaign.id -> CampaignAndTracking(campaign.id, campaign.brand, campaign.beginDate, campaign.endDate
      , campaign.campaign, campaign.url, campaign.adslotType, campaign.targetType, tracking.landingpage, tracking.id, tracking.publisher, tracking.adslot,
      tracking.creative, tracking.kpiType, tracking.kpiValue, campaign.deviceType, tracking.channel, tracking.adType, tracking.region, tracking.vertical)
    }
    value.toMap


  }
}
