我创建了以下代码行,以便成功将数据输入到数据库和jtable中,除了我的passport(image)列之外它们都工作,它将字节提交到数据库和jtable但不显示图片在jlabel上,与其他代码不同,它们也在jtextfield,combobox等中显示各自的数据我真的需要它使用这种格式,虽然我用其他方式工作(见下面的代码),但我更喜欢这种方式
private void SubmitActionPerformed(java.awt.event.ActionEvent evt) {
try {
String reg1 = reg.getText();
String name1 = name.getText();
String address1 = address.getText();
String parent_name1 = Parent_name.getText();
String Phone_no1 = Phone_no.getText();
String DateOfBirth1 = ((JTextField)DateOfBirth.getDateEditor().getUiComponent()).getText();
String class1 = ClassComboBox.getSelectedItem().toString();
String GenderCombobox11 = GenderCombobox1.getSelectedItem().toString();
String term1 = TermComboBox.getSelectedItem().toString();
byte[] passport1 = upload_path.getText().getBytes();
format = new ImageIcon(passport1);
imagLabel.setIcon(ResizeImage(format));
String query = "insert into JSS1_DB (reg_no, name, address, parent_name, parent_no, D_O_B, class, Gender, term, passport)"
+ "values('"+reg1+"','"+name1+"', '"+address1+"', '"+parent_name1+"', '"+Phone_no1+"', '"+DateOfBirth1+"',"
+ " '"+class1+"', '"+GenderCombobox11+"', '"+term1+"', '"+passport1+"')";
PreparedStatement pst;
pst = db_connector.prepareStatement(query);
pst.execute();
Object[] objs = {reg1, name1, address1, parent_name1, Phone_no1, DateOfBirth1, class1, GenderCombobox11, term1, passport1};
JOptionPane.showMessageDialog(null, "Submitted successfully");
pst.close();
JSS1_class JSS1 = new JSS1_class();
model = (DefaultTableModel) JSS1.JSS1_Table.getModel();
model.addRow(objs);
} catch (SQLException ex) {
JOptionPane.showMessageDialog(null, "Kindly Input unique Student's registration no");
ex.printStackTrace();
}
}
