mysql-connector-java-8.0.22.jar 复制到文件夹： C:\Development\payara520202\glassfish\domains\domain1\lib\ext

我还没做什么

在文件mysql-connector-java-8.0.22.jar中 路径数据源类名： com.mysql.cj.jdbc.MysqlDataSource 我改变了道路

但这没用。

错误是相同的。

请提供一个完整的异常堆栈跟踪，现在，您只提供了堆栈跟踪的底部，没有任何实际的错误消息。不确定这是否是问题的原因（由于缺少异常信息），但是

com.mysql.cj.jdbc.MySqlDataSource

不是

javax.sql.ConnectionPoolDataSource

，您需要选择

javax.sql.DataSource

，或者使用

com.mysql.cj.jdbc.MySqlConnectionPoolDataSource
