Question

我正在尝试根据官方文档here将我的播放应用与hibernate连接。我的persistence.xml文件`http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" 版本=＆＃34; 2.1＆＃34;＆GT;

<persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <non-jta-data-source>DefaultDS</non-jta-data-source>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
    </properties>
</persistence-unit>

但是，在将JPAApi注入控制器构造函数后，我收到以下错误：

    `[ERROR] [11/07/2017 17:37:08.944] [play-dev-mode-akka.actor.default-dispatcher-6] [akka.actor.ActorSystemImpl(play-dev-mode)] Internal server error, sending 500 response
com.google.common.util.concurrent.UncheckedExecutionException: java.lang.IllegalArgumentException
    at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2218)
    at com.google.common.cache.LocalCache.get(LocalCache.java:4147)
    at com.google.common.cache.LocalCache.getOrLoad(LocalCache.java:4151)
`

它像DI机制一样无法找到适当的实现到JPAApi接口。我该如何解决这个问题？

玩框架2.6注入JPAApi
