Kotlin Lagom 服务的 PersistenceException

Question

当服务在 kube 启动时，我有错误：

2020-09-16T22:01:17.370+0300 [warn] com.lightbend.lagom.internal.javadsl.persistence.jpa.JpaSessionImpl [] - Exception while initializing JPA EntityManagerFactory
javax.persistence.PersistenceException: No Persistence provider for EntityManager named defaultPersistenceUnit
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:85)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54)
    at com.lightbend.lagom.internal.javadsl.persistence.jpa.JpaSessionImpl.lambda$createEntityManagerFactory(JpaSessionImpl.java:107)
    at com.lightbend.lagom.internal.javadsl.persistence.jpa.Retry.$anonfun$retry(Retry.scala:37)
    at scala.concurrent.Future$.$anonfun$apply(Future.scala:659)

我有 lagom、kotlin、Hibernate。运行在 k8s。 Persistence.xml 在 /src/main.resources/META-INF

    <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <non-jta-data-source>DefaultDS</non-jta-data-source>

Application.conf:

lagom.persistence.jpa {
  # This must match the name in persistence.xml
  persistence-unit = "defaultPersistenceUnit"
}

无法理解错误的原因。

Answer 1

您可能应该将 jpa.default="defaultPersistenceUnit" 添加到您的 application.conf 文件中。
