java“无法构建实体管理器工厂”在运行用Maven编译的jar文件时出现Hibernate异常
我创建了一个具有多个依赖项的Java8SE应用程序，并使用Maven提供所需的库；它还使用JPA2.2和Hibernate4.3.6，两者都是通过maven提供的，当从Intellij运行它时，它工作得很好
我需要将其打包并在远程Linux服务器上运行，当我尝试通过Maven（mvn compile assembly:single）编译它时，它会正确地创建一个带有依赖项的jar，但当我在本地机器或远程服务器上运行它时，应用程序在需要连接到数据库时立即失败，并出现以下错误：

数据库url是正确的，因为它运行在特定的机器上，我通常在本地机器上运行应用程序时通过SSH创建端口隧道
编辑
这是处理数据库连接的类：
package util;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
public enum PersistenceManager {
INSTANCE;
private EntityManagerFactory emFactory;
private PersistenceManager() {
// "jpa-example" was the value of the name attribute of the
// persistence-unit element.
emFactory = Persistence.createEntityManagerFactory("my-jpa-pu");
}
public EntityManager getEntityManager() {
return emFactory.createEntityManager();
}
public void close() {
emFactory.close();
}
}
这个方法是第一个被调用的访问数据库的方法，在jar中运行时失败：
public static UtilsEntity getGameDate() {
EntityManager em = PersistenceManager.INSTANCE.getEntityManager();
UtilsEntity gameDate = (UtilsEntity) em.createQuery("SELECT u FROM UtilsEntity u WHERE u.name = 'GAME_DATE'").getSingleResult();
em.close();
return gameDate;
}
编辑2:我在这里发布了错误的数据库类，用正确的数据库类修复
