將JXDatePicker的日期格式轉換為mysql的日期類型以將其存儲在Java中的數據庫中

Question

我在Java應用程序中使用了JXDatePicker，我想將其值存儲在MySQL數據庫中。 要存儲的數據庫值是日期類型。

這是我的代碼：

final JXDatePicker dodc = new JXDatePicker(System.currentTimeMillis());
final SimpleDateFormat formater = new SimpleDateFormat("yyyy/MM/dd");
Date datedodc;

dodc.setBounds(250, 260, 150, 20);
    content.add(dodc);
    dodc.setForeground(BLACK);
    dodc.setBackground(WHITE);
    dodc.setFont(new Font("Arial", Font.BOLD, 12));
    dodc.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
             datedodc = dodc.getDate();
            System.out.println(formater.format(dodc.getDate()));
        }
    });

如果我打印此值，它將給出以下輸出：

Feb 05 00:00:00 IST 2013

我想將日期類型值存儲在mysql中，格式為： yyyy-mm-dd我該怎么做？

當我嘗試存儲值時，Eclipse給了我以下錯誤：

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Feb 05 00:00:00 IST 2013,Mon Feb 18 00:00:00 IST 2013,'Gujju Enterprise',4,'faaf' at line 1

Answer 1

嘗試：

DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
jXDatePicker1.setFormats(dateFormat);
DateFormat sysDate = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
String date_to_store = sysDate.format(jXDatePicker1.getDate()).toString();

這將為您提供jXDatePicker1 （此處未包括聲明和jXDatePicker1 ）輸入， date_to_store輸入為格式正確的String date_to_store輸出，以存儲在mySQL中。

Answer 2

嘗試這個：

DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
dateString = format.format(date.getDate());

Answer 3

試試這個方法：

int selectedYear =  (int)  datePicker.getModel().getYear();
int selectedMonth = (int)  datePicker.getModel().getMonth();
int selectedDay = (int)  datePicker.getModel().getDay();

String selectedDate = selectedYear +"-"+selectedMonth+"-"+selectedDay;

現在，您可以將selectedDate存儲在數據庫中。
