这是我的书模型：

package models

import play.api.db._
import play.api.Play.current

import scala.slick.driver.PostgresDriver.simple._
import scala.slick.ql.{MappedTypeMapper}
import scala.slick.session.{Session,Database}

case class Book(name: String,filename: String)

object Book extends Table[(Long,String,String)]("book") {

  lazy val database = Database.forDataSource(DB.getDataSource())
  def id = column[Long]("id",O PrimaryKey,O AutoInc)
  def name = column[String]("name",O NotNull)
  def filename = column[String]("filename",O NotNull)
  def * = id ~ name ~ filename

  def findAll() : Seq[Book] = database.withSession { implicit db:Session =>
    (for(t <- this) yield t.name ~ t.filename).list.map(attrs => Book(attrs._1,attrs._2))
  }

  def create(book: Book): Unit = database.withSession { implicit db:Session =>
    this.name ~ this.filename insert(book.name,book.filename)
  }

}

编辑：
这是我的Build.scala

import sbt._
import Keys._
import PlayProject._

object ApplicationBuild extends Build {

    val appName         = "PlayWithScala"
    val appVersion      = "1.0-SNAPSHOT"

    val appDependencies = Seq(
      // Add your project dependencies here,"postgresql" % "postgresql" % "9.1-902.jdbc4","com.typesafe" % "slick_2.10.0-M4" % "0.10.0-M2"
    )

    val main = PlayProject(appName,appVersion,appDependencies,mainLang = SCALA).settings(
      // Add your own project settings here      
    )

}
