Asalamualaikum, ini adalah artikel lanjutan dari Artikel Sebelumnya, sehingga di butuhkan project di dari artikel sebelum nya.
Artikel kali ini akan membahas update data dengan hibernate, tidak banyak yang akan di modifikasi dari project sebelum nya, kita cukup modifikasi file FormCRUD.java pada artikel sebelumnya.

FormCRUD.java

    }
}
Penjelasan Perubahan Kode :

 Modifikasi 1. Mengimplement MouseListener

                                              /*PENAMBAHAN 1 : Implemet MouseListener*/
public class FormCRUD extends javax.swing.JFrame implements  KeyListener,MouseListener{

    /**
     * Creates new form FormCRUD
     */

Modifikasi 2. Menambahkan MouseListener ke tblKaryawan (JTable)
     public FormCRUD() {
        initComponents();
        
        txtKriteria.addKeyListener(this);
        tableHandler.fillGrid(tblKaryawan,"");
        
        /*PENAMBAHAN 2*/
        tblKaryawan.addMouseListener(this);
    }

Modifikasi 3. Meng-overide method mouseClicked
    /*PENAMBAHAN 3*/
    @Override
    public void mouseClicked(MouseEvent e) {
        //throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
        txtNik.setText(tblKaryawan.getValueAt(tblKaryawan.getSelectedRow(), 0).toString());
        txtNama.setText(tblKaryawan.getValueAt(tblKaryawan.getSelectedRow(), 1).toString());
        txtAlamat.setText(tblKaryawan.getValueAt(tblKaryawan.getSelectedRow(), 2).toString());
    }

Karena pada artikel sebelumnya, pada tombol simpan  telah digunakan method saveOrUpdate() untuk menyimpan data, maka tidak akan ada modifikasi lagi di bagian tersebut.

       private void tbnSimpanActionPerformed(java.awt.event.ActionEvent evt) {                                          
        // TODO add your handling code here:
             try {
            try {
                new SchemaBuilder().build();
            } catch (Exception ex) {
                JOptionPane.showMessageDialog(null, ex.getMessage());
            }

            Karyawan k = new Karyawan(txtNik.getText(), txtNama.getText(), txtAlamat.getText());
            SessionFactory sf = new Configuration().configure().buildSessionFactory();
            Session s = sf.openSession();
            s.beginTransaction();
            s.saveOrUpdate(k);
            s.getTransaction().commit();
            sf.close();
            JOptionPane.showMessageDialog(null, "tersimpan");
            tableHandler.fillGrid(tblKaryawan,txtKriteria.getText());
            clearForm();
        } catch (HibernateException e) {
            JOptionPane.showMessageDialog(null, e.getMessage());
        }
    }

Coba lakukan uji program.

Disisi User Interface saya menggunakan Java destop saja, sedangkan IDE saya menggunakan Netbeans. Berikut Sofware yang di butuhkan : -Database MySQL(saya menggunakan paket XAMPP) -Netbeans -JDK Jika belum ada silahkan di instal terlebih dahulu. Langkah 1. Siapkan Database Buat database dengan nama "hrd", dalam database tersebut buat tabel dengan nama karyawan, field dari tabel karyawan tersebut sebagai berikut : ------------------------------------------ #nik(PK)       varchar(50)   primary key   nama           varchar(50)   alamat         varchar(50) ------------------------------------------ Langkah 2. Buatlah Project Baru di Netbeans dengan nama CobaHibernate. Pilih Categories->Java, Project -> Java Application, seperti gambar di bawah, saya memberi nama project Langka...
