我正在与 Derby 一起开发 Hibernate。但是当我在家配置时，我收到错误“java.sql.SQLException:没有合适的驱动程序”
以下是我的配置详细信息

我尝试了 Derby 中可用的所有类型的驱动程序。 我尝试了 Hibernate 中所有可用的 derby 方言。 我也从后台启动了 Derby 网络服务器。 我在数据源资源管理器中配置了数据库，我可以连接到 Derby 我设置了 Derby 的 DERBY_HOME、路径、lib。
我尝试在 hbm2ddl.auto 标记中使用 create 和 create-drop 选项。
仍然无法成功建立连接。
对此有任何指导。
最佳答案
尝试注释掉
<property name="connection.driver.class">org.apache.derby.jdbc.EmbeddedDriver</property>属性(property)。在最近的 JAR 中，没有这样的驱动程序。 Hibernate 应该从 URL 推断驱动程序。
它对我来说是一个使用联网 Derby 数据库的示例。 http://zetcode.com/hibernate/derby/
关于java - Hibernate Derby 连接问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57866505/
