【问题描述】：
在 IntelliJ Idea 中，我使用 JPA 2.1 和 hibernate 4.3.10 final 创建了一个项目。创建数据源（测试连接：成功）后，我从数据库生成了持久性映射。项目编译没有错误。当我尝试使用简单的 Select * 查询在 JPA 控制台中进行测试时，它返回以下异常：
[2015-05-21 16:01:27] javax.persistence.PersistenceException: Unable to locate persistence units
[2015-05-21 16:01:27] java.lang.RuntimeException: javax.persistence.PersistenceException: Invalid persistence.xml.

谁能告诉我如何解决这个错误？我搜索和阅读了大约 10 个小时，但没有成功

如果我尝试在 Wildfly 上部署应用程序而不从数据库创建实体，它将部署应用程序。但是，如果我在创建实体后尝试部署应用程序，则会收到以下错误：
