SLICK基础

1.sbt添加依赖

  "com.typesafe.slick" %% "slick" % "3.2.3",
  "org.slf4j" % "slf4j-nop" % "1.6.4",
  "com.typesafe.slick" %% "slick-hikaricp" % "3.2.3",
  "mysql" % "mysql-connector-java" % "5.1.47",

2.数据库配置：src/main/resources/application.conf

indie-db = {
  url = "jdbc:mysql://devhdp3:3307/indie?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&noAccessToProcedureBodies=true&useSSL=false"
  driver = "com.mysql.jdbc.Driver"
  keepAliveConnection = true
  user = "root"
  password = "123456"
  connectionPool = disabled
  connectionTestQuery = "SELECT 1"
  connectionTimeout = 30 second
}

3.代码

package org.netsharp.persist

import slick.jdbc.MySQLProfile.api._

import scala.concurrent.duration._
import scala.concurrent.{Await, Future}

object Db2 {
  //实体定义
  final case class Message(
                            sender: String,
                            content: String,
                            id: Long = 0L)

  //元数据定义
  final class MessageTable(tag: Tag) extends Table[Message](tag, "message") {
    def id = column[Long]("id", O.PrimaryKey, O.AutoInc)
    def sender = column[String]("sender")
    def content = column[String]("content")
    def * = (sender, content, id).mapTo[Message]
  }

  def main(args:Array[String]): Unit ={

    val messages = TableQuery[MessageTable]

    //数据库访问对象
    val db = Database.forConfig("indie-db")

    //创建表
    val setupFuture = db.run(messages.schema.create)
    val result = Await.result(setupFuture, 5.seconds)

    //插入数据
    def freshTestData = Seq(
      Message("Dave", "Hello, HAL. Do you read me, HAL?"),
      Message("HAL", "Affirmative, Dave. I read you."),
      Message("Dave", "Open the pod bay doors, HAL."),
      Message("HAL", "I'm sorry, Dave. I'm afraid I can't do that.")
    )

    val insert: DBIO[Option[Int]] = messages ++= freshTestData
    val result2: Future[Option[Int]] = db.run(insert)
    val rowCount = Await.result(result2, 2.seconds)

    //查询数据
    val halSays = messages.filter(_.sender === "HAL").result
    val messagesFuture: Future[Seq[Message]] = db.run(halSays)
    val list = Await.result(messagesFuture, 2.seconds)
    list.foreach(println)
  }
}

4.上面例子是基于mysql的，对于sqlserver需要如下修改

a,sbt添加sqlserver的jdbc包依赖："com.microsoft.sqlserver" % "mssql-jdbc" % "7.0.0.jre8",

b.添加配置

indie-sqlserver = {
  url = "jdbc:sqlserver://host_or_ip;database=REMInformation;useUnicode=true&characterEncoding=UTF-8"
  driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
  keepAliveConnection = true
  user = "xxxx"
  password = "xxxx"
  connectionPool = disabled
  connectionTestQuery = "SELECT 1"
  connectionTimeout = 30 second
}

c.代码中原来的import

 import slick.jdbc.MySQLProfile.api._

改成新的import

import slick.jdbc.SQLServerProfile.api._

d.代码中原来的数据库配置读取

val db = Database.forConfig("indie-db")

改为

val db = Database.forConfig("indie-sqlserver")
