播放2.4.x包play.db.ebean不存在

Question

使用激活器创建新应用程序后，我尝试连接到数据库并配置连接到数据库所需的所有必要步骤（通过Play网站进行跟踪）。

我无法成功并始终遇到此错误。

这是我的build.sbt

name := """xxxxx"""

version := "1.0-SNAPSHOT"

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

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
  javaJdbc,
  javaJpa,
  cache,
  javaWs,
  evolutions
)
libraryDependencies += specs2 % Test

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

lazy val root = (project in file("."))
  .enablePlugins(PlayJava, PlayEbean)


// Play provides two styles of routers, one expects its actions to be injected, the
// other, legacy style, accesses its actions statically.
routesGenerator := InjectedRoutesGenerator

[已更新]这是我的projects/plugins.sbt

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.3")

// Web plugins
addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.0.6")
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.3")
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.7")
addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

// Play enhancer - this automatically generates getters/setters for public fields
// and rewrites accessors of these fields to use the getters/setters. Remove this
// plugin if you prefer not to have this feature, or disable on a per project
// basis using disablePlugins(PlayEnhancer) in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")

// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using
// enablePlugins(SbtEbean). Note, uncommenting this line will automatically bring in
// Play enhancer, regardless of whether the line above is commented out or not.
//addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

这是我的application.conf

# Configure Ebean
ebean.default = ["models.*"]

#JPA Configuration
jpa.default=defaultPersistenceUnit

# Database configuration
# ~~~~~
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
#
 db.default.driver=org.h2.Driver
 db.default.url="jdbc:h2:mem:play"
 db.default.username=sa
 db.default.password=""

播放2.4.x中是否弃用了play.db.ebean.Model？

我附上了错误的屏幕截图。

Answer 1

2.4中的

As announced before默认情况下不再启用Ebean。幸运的是，它仍然受支持，您可以轻松启用它。

1. 在project/plugins.sbt取消注释最后一行：

   addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")
   

2. 在build.sbt将PlayEbean插件添加到root：

   lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
   

另外正如您现在注意到的那样，您应该使用原生Ebean＆＃39; com.avaje.ebean.Model代替play.db.ebean.Model

最后，您现在应该为没有ID类型的模型声明一个Finder，因此它将是：

public static final Finder<Long, Foo> find = new Finder<>(Foo.class);

而不是

public static final Finder<Long, Foo> find = new Finder<>(Long.class, Foo.class);

你需要运行：     发挥想法或激活者的想法     玩日食或激活日食

在添加依赖项之后，您需要为特定IDEA（Eclipse，intellij）重新生成代码。
