mysql Java EE+Wildfly:无法启动服务jboss。持久性单位

3 周，6 日 Questions & Answers

我正在尝试设置一个maven项目来使用Wildfly和MySql，我得到了这个错误，我很确定这是一个配置问题。我使用的是Wildfly，所以我没有任何hibernate配置文件（与我找到的所有解决方案相关）。这就是我得到的。我刚刚开始学习如何处理RIA的问题，所以任何想法都将非常感谢

问题主要是错误日志和代码，所以感谢所有愿意帮助的人的耐心

我的控制台错误：

共 (2) 个答案

  1. # 1 楼答案

    将<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>添加到持久性中。xml

    您还应该从Hibernate4.3中不推荐使用的org.hibernate.ejb.HibernatePersistence迁移到org.hibernate.jpa.HibernatePersistenceProvider
