线程 "main" javax.persistence.PersistenceException 中的异常：没有名为 lanceurApplication 的 EntityManager 的持久性提供程序
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named lanceurApplication
我正在尝试使用 JPA 和 Hibernate 为 Java 项目设置持久性。我的数据库使用 Oracle 11g Express。
我已经处理这个问题好几个小时了，但是无论我做什么，当我尝试创建一个 EntityManagerFactory 时，我总是会遇到这个异常：我发现了很多关于这个异常的类似问题，但没有我能够解决的问题开始工作。我在这里做错了什么？
详细：
我收到的错误是：

1-删除所有库 jar
2-再次添加属性 -> Java 构建路径 -> 添加 JAR
3-项目 -> 清理
4-用spring3修改
