select JDatechooser from String Sql

Question

当我选择return book date from JDateChooser并点击enter button..the时，JTable中没有显示return date。

private void jButton19ActionPerformed(java.awt.event.ActionEvent evt) {                                          
    try
    {
        ((JTextField)jDateChooser7.getDateEditor().getUiComponent()).getText();

        String sql="select * from borrowed_book_record where return_date='"+jDateChooser7.getDateFormatString()+"'";



        pst=conn.prepareStatement(sql);
        rs=pst.executeQuery();


        jTable4.setModel(DbUtils.resultSetToTableModel(rs));
        jTable4.setVisible(true);

    }
    catch(Exception e)
    {
        JOptionPane.showMessageDialog(null,""+e,"Error",JOptionPane.ERROR_MESSAGE);
    }

}

Answer 1

没有任何示例，我只能猜测日期格式。根据sql查询返回的日期格式检查日期组件的日期格式！
