我试图通过遵循Hibernate EntityManager
文档中的信息来建立一个简单的jpa
2.0项目。我已经花了几个小时了，但是无论我做什么，当我尝试创建EntityManagerFactory时总是会遇到此异常：

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named manager1
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:32)
    at se.mycomp.UserTest.main(UserTest.java:9)

关于此异常，我发现了很多类似的问题，但是没有能够解决的解决方案。我在这里做错了什么？
