public class App {
    public static void main(String[] args) throws Exception {
        
        Class.forName("com.mysql.cj.jdbc.Driver");
        
        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/vip?serverTimezone=GMT&useSSL=false", "root", "zhangpn");
        
        Statement stat = conn.createStatement();
        
        boolean flag = stat.execute("INSERT INTO `sys_user` VALUES (‘2‘, ‘0003‘, ‘bdmin‘, ‘123456‘)");
