jdbcUser定义连接数据库的用户名。

JdbcUser defines the username to connect to the database.

youdao

对于模式名称，可以使用连接数据库所用的用户名(在本例中，我使用ADMINISTRATOR)。

As the schema name, you can use the username by which you connect to the database (in my case, I have to admit that's ADMINISTRATOR).

还指定了 JDBC 驱动程序类、数据库用户名和连接数据库（在这个数据库中已经创建了 users 和 usergroup 表）所用的 JDBC URL。

I have provided values for the JDBC driver class, the database user name, and a JDBC URL to connect to the database, in which you have already created the users and usergroup tables.
