播放框架：无法注入数据库对象

Question

我正在尝试使用play框架连接到mysql。我是新手，无法找出确切的问题。任何帮助将受到高度赞赏。

conf\application.conf中的配置如下：

  config = "db"
  default = "default"
  db.default.driver=com.mysql.jdbc.Driver
  db.default.url="jdbc:mysql://localhost/ng_play"
  db.default.username=root
  db.default.password="****"
  ebean.default = ["models.*"]

build.sbt

name := """play-scala-tutorial-one"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  jdbc,
  cache,
  ws,
  "mysql" % "mysql-connector-java" % "5.1.36",
  "org.scalatestplus.play" %% "scalatestplus-play" % "1.5.1" % Test
)

resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"

Answer 1

Mysql版本和数据库连接器版本不匹配。并且将此db.default.hikaricp.connectionTestQuery="SELECT TRUE"添加到application.conf有助于缓解一个问题。
