Question

我使用play 2.3.6和JPA ORM来处理数据，所以我按照playframework（https://www.playframework.com/documentation/2.3.x/JavaJPA）的文档进行操作，但我不知道为什么包play.db.jpa没有导入进入我的项目。

我尝试清理我的项目（激活干净，激活干净文件）但没有改变

错过了什么工作？

下面是我的配置：

build.sbt

name := "play_sample1"

version := "1.0"


libraryDependencies ++= Seq(  
  javaJdbc,  
  cache,
  javaWs,
  javaJpa,
  "org.hibernate" % "hibernate-entitymanager" % "4.3.6.Final",  
  "mysql" % "mysql-connector-java" % "5.1.18"
)

lazy val root = (project in file(".")).enablePlugins(PlayJava) 
                    .aggregate(common, webstats)  
                    .dependsOn(common, webstats)                 

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

lazy val common = (project in file("modules/common")).enablePlugins(PlayJava).dependsOn(core)
lazy val webstats = (project in file("modules/webstats")).enablePlugins(PlayJava).dependsOn(common)

appplication.conf

# This is the main configuration file for the application.
# ~~~~~

# Secret key
# ~~~~~
# The secret key is used to secure cryptographics functions.
#
# This must be changed for production, but we recommend not changing it in this file.
#
# See http://www.playframework.com/documentation/latest/ApplicationSecret for more details.
application.secret="yIX1uonulRO^O8A56tlkb1c4aJS^@9k<dr@^mDXuSBXggKHMRJykv@>``Ra?yh<i"

# The application languages
# ~~~~~
application.langs="en"

# Global object class
# ~~~~~
# Define the Global object class for this application.
# Default to Global in the root package.
# application.global=Global

# Router
# ~~~~~
# Define the Router object to use for this application.
# This router will be looked up first when the application is starting up,
# so make sure this is the entry point.
# Furthermore, it's assumed your route file is named properly.
# So for an application router like `conf/my.application.Router`,
# you may need to define a router file `my.application.routes`.
# Default to Routes in the root package (and `conf/routes`)
# application.router=my.application.Routes

# Database configuration
# ~~~~~
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/play_test"
db.default.user=root
db.default.password=""

jpa.default=defaultPersistenceUnit
db.default.jndiName=DefaultDS

# You can expose this datasource via JNDI if needed (Useful for JPA)
# db.default.jndiName=play_test

# Evolutions
# ~~~~~
# You can disable evolutions if needed
# evolutionplugin=disabled

# Ebean configuration
# ~~~~~
# You can declare as many Ebean servers as you want.
# By convention, the default server is named `default`
#
# ebean.default="models.*"

# Logger
# ~~~~~
# You can also configure logback (http://logback.qos.ch/),
# by providing an application-logger.xml file in the conf directory.

# Root logger:
logger.root=ERROR

# Logger used by the framework:
logger.play=INFO

# Logger provided to your application:
logger.application=DEBUG
