在尝试将它与Oracle一起使用时，我从Hibernate得到了一个非常模糊的例外。（它在MySQL中正常工作）
我有以下配置：
Play Framework：2.3.7
ojdbc14.jar的
休眠：4.3.8.Final
我正在使用Oracle 10i
应用程序设法连接，但在尝试构建实体管理器时失败。 我尝试手动构建它，但是在使用Play的注释 @ play.db.jpa.Transactional 时出现了同样的错误 例如：通过原始JDBC访问正常工作。
我在application.conf中的数据库设置：
db.default.driver=oracle.jdbc.driver.OracleDriver
db.default.url="jdbc:oracle:thin:@IP:1521:SID"
db.default.user=USER_NAME
db.default.pass=ROOT
db.default.jndiName=DefaultDS
jpa.default=defaultPersistenceUnit
My 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

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
</properties>
</persistence-unit>
</persistence>
以下是例外：

由于我没有使用游戏，我的答案不是复制和粘贴，但它会告诉你如何做到这一点。
您的持久性单元中似乎缺少很多属性。您没有提供必填字段，如用户名，密码，网址架构等。请查看：
https://docs.jboss.org/hibernate/entitymanager/3.5/reference/en/html/configuration.html
hsqldb的一个例子来自上面的文档：
<persistence>
<persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL">

<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:."/>

该问题与Oracle驱动程序有关。
我的原始配置适用于驱动程序ojdbc7.jar
所以我的play / jpa配置保持为：

jpa.default=defaultPersistenceUnit
