我正在尝试使用JPA为我目前参与的JavaEE项目设置持久性，并且在配置方面遇到了许多问题。目前，我在persistence.xml中定义了一个RESOURCE_LOCAL persistence unit，目的是在单元测试中使用这个单元，并在解决设置JTA持久性单元及其相应的JTA数据源之前验证其他所有功能。然而，即使是这种“简单”的情况也会导致错误

详细内容：

我得到的错误是：

javax.persistence.PersistenceException: No Persistence provider for EntityManager named kronosTestLocal
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:69)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:47)
    at persistence.EntityManagerTest.getStaff(EntityManagerTest.java:56)
    at persistence.EntityManagerTest.setup(EntityManagerTest.java:17)
    ...

在JUnit测试中引发错误的代码段如下所示：

private final String persistenceUnitName = "kronosTestLocal";
....
final EntityManagerFactory entityManagerFactory =
    Persistence.createEntityManagerFactory(persistenceUnitName);

persistence.xml（位于META-INF内部，并在intellij JPA方面声明）：（我试着移除kronos持久性单元，以防它以某种方式干扰，但没有帮助）

从我的研究中，我看到很多人都经历过类似的问题，但从我所能看出，我没有犯任何常见的错误。我们中的一些人已经尝试解决这个问题一段时间了，所以欢迎任何帮助

如果您是在JUnit测试中执行此操作的，并且使用maven，

persistence.xml

应该位于

src/test/resources/META-INF/persistence.xml中，它将在测试执行时放在正确的位置。src/main/resources/META-INF/
中的文件未被使用，因为它不在测试jar的路径中。完美，修复了它！谢谢。实际上，我们在META-INF上的persistence.xml与src处于同一级别。修复方法只是删除分解的目标文件夹并让它重新部署。
