java - 在java中获取今天的日期

Question

这是我的数据库:

date          status
1343469690     Q
1343470540     C
1343470556     P

我写了这段代码:

public class TodayQ {

    public int data() {
        int count = 0;
        //count++;

        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/pro", "root", "");

            PreparedStatement statement = con.
                    prepareStatement("select * from orders where status='Q' AND date=CURDATE()");
            ResultSet result = statement.executeQuery();
            while (result.next()) {
                // Do something with the row returned.
                count++; //if the first col is a count.
            }
        } catch (Exception exc) {
            System.out.println(exc.getMessage());
        }
        return count;
    }
}

当日期采用 yyyy-mm-dd 格式时，它可以成功运行。但现在我的日期是 1343469690 格式的时间戳。如何获取计数值？

如果它实际上是时间戳，那么您就有日期:请参阅 http://docs.oracle.com/javase/7/docs/api/java/sql/Timestamp.html 。将时间戳转换为日历 (http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html) 很简单:请参阅 Calendar.setTimeInMillis() 方法。
