I can not import play.db.jpa.Model into my model

I cannot somehow import play.db.jpa.Modellib into my model, it can only find play.db.ebean.Model. Is there any way to import this?

thank

This is because it play.db.jpa.Modelis Play 1.x and play.db.ebean.Modelis Play 2.x.

To use JPA in Play 2.x, see http://www.playframework.org/documentation/2.0/JavaJPA

The class play.db.jpa.Model is not available in game 2.0. The solution I found for this problem:

  • In YourProject/conf/application.confdeclare JPA configuration:

db.default.driver = org.h2.Driver
db.default.url = "jdbc: h2: mem: play"
db.default.jndiName = DefaultDS

:

jpa.default = defaultPersistenceUnit

  • META-INF YourProject/conf/

  • persistence.xml:

 <persistence xmlns="http://java.sun.com/xml/ns/persistence"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
                 version="2.0">

        <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
            <provider>org.hibernate.ejb.HibernatePersistence</provider>
            <non-jta-data-source>DefaultDS</non-jta-data-source>
            <properties>
                <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
            </properties>
        </persistence-unit>


</persistence>
  • YourProject/project/Build.scala , :

val appDependencies = Seq (
  // ,
  javaCore,
  javaJdbc,
  javaJpa,
  " org.hibernate "%" hibernate-entitymanager "%" 4.2.1.Final "
)

Ebean, :

val main = play.Project(appName, appVersion, appDependencies).settings(
  ebeanEnabled := false 
)
