通过jdbc运行shell命令

我一直在尝试:

Class.forName("com.mysql.jdbc.Driver");
        connect = DriverManager.getConnection("jdbc:mysql://" + this.host + "/" + this.db + "?", properties);
        statement = connect.createStatement();
        String sql = "\\! touch /home/dbsms/testfile";
        statement.execute(sql);
