Perisistence异常：没有EntityManager的持久性提供程序名为defaultPersistenceUnit

Question

我是PLAY框架的新手。我一直收到这个错误。我似乎没有发现代码有任何问题。请帮帮我。

CONF / META-INF / persistence.xml中：

<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.MySQLInnoDBDialect"/>
        </properties>
    </persistence-unit>

</persistence>

我的application.conf：

db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
db.default.jndiName=DefaultDS
jpa.default=defaultPersistenceUnit
ebean.default="model.*" // cuz my folder is model and not models.

我对实体经理的呼吁：

		EntityManagerFactory emf = Persistence.createEntityManagerFactory("defaultPersistenceUnit");

请帮帮我！
