当我们尝试使用带有数据源的 spging 映射 (jndi-lookup) 的 hibernate 连接数据库时，会出现此错误。我在面板上附加了完整的堆栈跟踪，请帮助它创建我的应用程序停止

从异常中，

Caused by: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'

很明显，您没有为 JDBC 指定驱动程序类。

我同意@TheKojuEffect 您的驱动程序名称未正确指定，请确保您放置了与您的数据库供应商匹配的正确类名
