我想可视化数据库并尝试使用SchemaSpy，但无法连接到数据库。这是一个mysql数据库，在我的计算机上运行，可在localhost下访问，我使用以下命令调用了SchemaSpy：
java -jar schemaspy-6.0.0.jar -t mysql -dp postgresql-42.2.7.jar -db <name> -host <host> -p <port> -s <name> -u <user> -p <password> -o ./output/
我下载了postgresql-42.2.7.jar作为驱动程序，并在调用中设置了相应的参数。我也尝试过完全不设置驱动程序，但是并没有改变输出。
我尝试运行SchemaSpy后收到以下错误消息：
SchemaSpy generates an HTML representation of a database schema's relationships.

我也尝试设置--illegal-access = warn参数，但没有更改。
有人知道可能是什么问题吗？
非常感谢！
问题来自您的驱动程序。您想用postgreSQL驱动程序描述一个MySql数据库。
看看：https://dev.mysql.com/downloads/connector/j/下载mysql驱动程序，然后将其替换为您的命令行
