PlayFlamework2.6でslickをコンパイル時DIしたときのメモ

依存性の追加

build.sbt

libraryDependencies ++= Seq(
  "com.typesafe.play" %% "play-slick" % "3.0.0",
  "mysql" % "mysql-connector-java" % "5.1.16",
  "com.typesafe.play" %% "play-slick-evolutions" % "3.0.0"
)

プロパティの定義

application.conf

play.application.loader = "com.exsample.MyApplicationLoader"

slick {
    dbs.default {
        profile = "slick.jdbc.MySQLProfile$"
        db {
            connectionPool = disabled
            driver = "com.mysql.jdbc.Driver"
            url = "jdbc:mysql://localhost/database_name?characterEncoding=UTF-8"
            user = "user"
            password = "password"
        }
    }
}

アプリケーションローダー

MyApplicationLoader.scala

package com.exsample

import play.api._
import play.api.ApplicationLoader.Context
import _root_.controllers.AssetsComponents
import com.exsample.controllers._
import com.exsample.repositories._
import play.filters.HttpFiltersComponents
import slick.jdbc.JdbcBackend.Database
import router.Routes

class MyApplicationLoader extends ApplicationLoader {
  def load(context: Context) = {
    new MyApplicationComponents(context).application
  }
}

class MyApplicationComponents(context: Context)
    extends BuiltInComponentsFromContext(context) with AssetsComponents
      with HttpFiltersComponents {

  // SlickController
  lazy val db = Database.forConfig("slick.dbs.default.db")
  lazy val slickRepository = new SlickRepositoryImpl(db)
  lazy val slickController = new SlickController(controllerComponents, slickRepository)

  // router
  lazy val router = new Routes(httpErrorHandler, slickController, assets)
  // ついでのメモ
  // ↑のnew Routesについて、第一引数はhttpErrorHandler、それ以降はroutesでの定義順に渡すっぽい
