求解：请问这段代码运行时为什么老是报错？
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.Date;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public class TestDate {
public static void main(String[] args)throws Exception {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc.mysql://localhost/mydata?user=root&pastword=root");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select pdate from article");
while(rs.next()) {
Date d = rs.getDate("pdate");
//SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日");
//System.out.println(sdf.format(d));
Calendar c = Calendar.getInstance();
c.setTime(d);
System.out.println(Calendar.MONTH);
}
rs.close();
stmt.close();
conn.close();
}
}
报错：Exception in thread "main" java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
