在我花了一天的时间之后，我现在在我的智慧结束。每当我部署我的应用程序时，我都会收到本文末尾的错误。我已经在glassfish控制台中创建了正确的数据源（当它被操作时）。我已将mysql连接器和hibernate都放在glassfish libs中。我不知道我还能做什么。 Mysql数据库有效。

您忘记在pressistant.xml文件中添加一些属性，这就是为什么无法从IDE和mySQL数据库建立连接的原因。 添加：
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/yourDatabaseName"/>
<property name="hibernate.connection.username" value="root"/>
<property name="hibernate.connection.password" value="root"/>
