java - 无法在数据库中保存日期(月/日/年)

Question

我正在使用java.sql.Connection和java.sql.Date要访问日期，这里是我的代码:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
     if(jTextArea1.getText().equals(""))
    JOptionPane.showMessageDialog(null, "Please Enter the Expence Description. ");

else if(jComboBox4.getSelectedIndex()<1)
    JOptionPane.showMessageDialog(null, "Please Select the Type.");

else if(jDateChooser1.getDate().equals(""))
    JOptionPane.showMessageDialog(null, "Please Enter the Date. ");

else if(jTextField3.getText().equals(""))
    JOptionPane.showMessageDialog(null, "Please Enter the Amount.");

else{
  try{
    con= DriverManager.getConnection("jdbc:mysql://localhost:3306/project","root","1234");
    ps=con.prepareStatement("insert into work values(?,?,?,?)");
    ps.setString(1, jTextArea1.getText());
    ps.setString(2, jCom.getDate());boBox4.getSelectedItem().toString());
    ps.setDate(3, (Date) jDateChooser1.getDate());

但它给出了错误

java.lang.ClassCastException: java.util.Date cannot be cast to java.sql.Date

谁能给出上述问题的解决方案吗？

Answer 1

ps.setDate(3, (日期) jDateChooser1.getDate());

不要在上面的代码中转换日期，而是将 util Date 转换为 sql Date，如下所示:

java.sql.Date date = new java.sql.Date(new java.util.Date().getTime());
