使用slick插入MySQL

我在ampps localhost服务器上的MySQL数据库中有一个名为“KLIJENTI”的表。该表由4列组成：ID_KLIJENTA-int、IME_KLIJENTA-string、PREZIME_KLIJENTA-string和ADRESA_KLIJENTA-string。 我遵循了有关如何使用slick插入和读取数据库的教程，但它并不能满足我的需要

这是我的application.conf：

scalaTest = {
url = "jdbc:mysql://localhost/Scala1"
user = "root"
password = "mysql"
driver = com.mysql.jdbc.Driver
connectionPool = disabled
keepAliveConnection = true
logStatements = true
}

build.sbt：

name := """project4"""

mainClass in Compile := Some("HelloSlick")

libraryDependencies ++= List(
  "com.typesafe.slick" %% "slick" % "3.1.0-RC2",
  "org.slf4j" % "slf4j-nop" % "1.7.10",
  "com.h2database" % "h2" % "1.4.187",
  "org.scalatest" %% "scalatest" % "2.2.4" % "test" ,
  "mysql" % "mysql-connector-java" % "5.1.28"
)

fork in run := true

这是我的helloSlick.scala：

import scala.concurrent.{Future, Await}
import scala.concurrent.ExecutionContext.Implicits.global
import scala.concurrent.duration.Duration
import slick.backend.DatabasePublisher
import slick.driver.MySQLDriver.api._


case class Klijent(ID_KLIJENTA: Option[Int] = None, IME_KLIJENTA: String, PREZIME_KLIJENTA: String, ADRESA_KLIJENTA: String)

class Klijenti(tag: Tag) extends Table[Klijent](tag, "KLIJENTI") {
  def ID_KLIJENTA = column[Option[Int]]("ID_KLIJENTA", O.PrimaryKey, O.AutoInc)
  def IME_KLIJENTA = column[String]("IME_KLIJENTA")
  def PREZIME_KLIJENTA = column[String]("PREZIME_KLIJENTA")
  def ADRESA_KLIJENTA = column[String]("ADRESA_KLIJENTA")

  def * = (ID_KLIJENTA, IME_KLIJENTA, PREZIME_KLIJENTA , ADRESA_KLIJENTA) <>((Klijent.apply _).tupled, Klijent.unapply)
}

// The main application
object HelloSlick extends App {

  val db = Database.forConfig("scalaTest")
  val mojiKlijenti = TableQuery[Klijenti]
  val q1 = sql"select IME_KLIJENTA from KLIJENTI WHERE ID==1 ".as[String]

  val q2 = mojiKlijenti.filter(_.ID_KLIJENTA === 0)

  println(q1)
  println(q2)

我的apache Web服务器和mysql已打开，以防万一有人问。。 为什么我得不到真正的价值

编辑：>稍后，我尝试执行以下命令

mojiKlijenti+=Klijent（一些（5），“名称”、“姓氏”、“地址”）

并且再次成功执行编译，但当我在phpmyadmin中检查数据库时，没有添加任何记录。

您没有获得实际值，因为您需要通过调用查询的结果方法将查询转换为操作并执行它

val action = q2.result
val results = db.run( action)
results.foreach( println )

我刚试过那段代码，它编译了，但它什么也不返回，结果什么也没有打印出来。这取决于过滤器

val q2=mojiKlijenti.filter（u.ID\u KLIJENTA==0）

get指定列中具有该值的行。我刚刚在数据库中添加了一行，ID\u KLIJENTA=2，第一行的值为ID_KLIJENTA=1，现在我将代码改为1，之后改为2，仍然没有结果，也没有打印任何内容：(

val action = q2.result
val results = db.run( action)
results.foreach( println )
