java - 启动 Wildfly 11 App Server 时出错 - 名为 null 的持久性单元

Question

我正在使用 Eclipse 和 Wildfly 11 开发基于 Maven 的 JSF+JPA+EJB 3.2 项目。 启动 App Server 时出现以下错误:

    ]

}

我在无状态 bean 中注入(inject) EntityManager:

@Stateless
public class UserManagementServiceSlsb implements UserManagementService {

     /** The Entity Manager */
     @PersistenceContext(name = "TELCOAppPU")
     private EntityManager entityManager;

     private UserManagementService userMgmtService;
 ....
}

为什么 Container 找不到 persistence.xml 文件？ persistence.xml 存在于 META-INF 目录中。任何帮助，将不胜感激。 谢谢。
更新 : 这是项目目录结构，persistence.xml 存在于 META-INF 目录中。

Project dir structure

persistence.xml 包含实体类和 MySql 数据库连接详细信息。

<persistence-unit name="TELCOAppPU">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <class>com.itsys.erp.server.dal.entities.City</class>

通过将 resources 文件夹(作为源文件夹)添加到路径 src/main/resources 并移动 META-INF 文件夹来解决它到 resources 文件夹，这反过来告诉 maven 将所有文件放在 resources 目录下到 target/classes 和 WEB-INF/WAR 中的类。
