关于 JDBC 连接 Mysql,求一个大佬

[hastyfish]

为什么用
Class.forName("com.mysql.cj.jdbc.Driver");
JdbcRowSet rowSet = RowSetProvider.newFactory().createJdbcRowSet();
rowSet.setUrl("jdbc:mysql://localhost:3306/sonoo");
rowSet.setUsername("root");
rowSet.setPassword("root");
rowSet.setCommand("select * from user420");
rowSet.execute();
会报错 java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/sonoo

用
Class.forName("com.mysql.cj.jdbc.Driver");
Connection con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/sonoo","root","root");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select * from user420");
就有结果

求大佬指导一下
