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

Question

我试图在我的Play应用程序中使用JPA,当我尝试加载我的应用程序时,我收到一个PersistenceException:没有为EntityManager提供持久性提供程序名为defaultPersistenceUnit

这些是我的设置: build.sbt

libraryDependencies ++= Seq(
   ....
  "mysql" % "mysql-connector-java" % "5.1.28",
  javaJpa,
  "org.hibernate" % "hibernate-entitymanager" % "3.6.9.Final"
)

CONF/META-INF/persistance.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.MySQLInnoDBDialect"/>
        </properties>
    </persistence-unit>

</persistence>

application.conf

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/testDB"
db.default.user="root"
db.default.password="root"
db.default.jndiName=DefaultDS
jpa.default=defaultPersistenceUnit

可以请有人告诉我我做错了什么......谢谢.

当您的上述信息正确时,我假设文件名拼写错误:重命名conf/META-INF/persistance.xml为conf/META-INF/persistence.xml.
