arraydata使用RMI进行jtable [重复](arraydata to jtable using RMI [duplicate])

这个问题在这里已有答案：

java.io.WriteAbortedException：写入已中止; java.io.NotSerializableException 2个答案

//我有返回列表的方法pulic列表，我想将数据显示到jtable中，怎么做？

从数据库中检索数据的方法

public List<mahasiswa> SelectMahasiswa() throws RemoteException { List <mahasiswa>listMahasiswa = new ArrayList<mahasiswa>(); try { PreparedStatement ps = con.prepareStatement("SELECT nim, nama, jurusan FROM mahasiswa"); ResultSet rs = ps.executeQuery(); while (rs.next()) { mahasiswa mhs = new mahasiswa(); mhs.setNim(rs.getString(1)); mhs.setNama(rs.getString(2)); mhs.setJurusan(rs.getString(3)); listMahasiswa.add(mhs); rs.close(); } } catch (SQLException e) { e.printStackTrace(); } return listMahasiswa; }

将数据显示给JTable

public void getAll(){ try { Registry regis = LocateRegistry.getRegistry("localhost", koneksi.Port_id ); remot rem = (remot) regis.lookup(koneksi.id); DefaultTableModel model=new DefaultTableModel(); for(mahasiswa mhs:rem.SelectMahasiswa()){ String kolom1=mhs.getNim(); String kolom2=mhs.getNama(); String kolom3=mhs.getJurusan(); String kolom[]={kolom1,kolom2,kolom3}; model.addRow(kolom); } jTable1.setModel(model); } catch (Exception ex) { ex.printStackTrace(); } }

错误信息

java.rmi.UnmarshalException：错误解组返回; 嵌套异常是：java.io.WriteAbortedException：写入中止; java.io.NotSerializableException：remot.mahasiswa，位于java.rmi.server的java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod（RemoteObjectInvocationHandler.java:194）的sun.rmi.server.UnicastRef.invoke（UnicastRef.java:193）。位于com.sun.proxy的RemoteObjectInvocationHandler.invoke（RemoteObjectInvocationHandler.java:148）。来自klaiyen.CRUD2的klaiyen.CRUD2.getAll（CRUD2.java:218）的$ Proxy0.SelectMahasiswa（未知来源）。（CRUD2.java:30）在klaiyen.CRUD2 $ 4.run（CRUD2.java:263）

//I have method pulic list that return list, i want to display data into jtable, how to do it?

methods that retrieve data from the database

public List<mahasiswa> SelectMahasiswa() throws RemoteException { List <mahasiswa>listMahasiswa = new ArrayList<mahasiswa>(); try { PreparedStatement ps = con.prepareStatement("SELECT nim, nama, jurusan FROM mahasiswa"); ResultSet rs = ps.executeQuery(); while (rs.next()) { mahasiswa mhs = new mahasiswa(); mhs.setNim(rs.getString(1)); mhs.setNama(rs.getString(2)); mhs.setJurusan(rs.getString(3)); listMahasiswa.add(mhs); rs.close(); } } catch (SQLException e) { e.printStackTrace(); } return listMahasiswa; }

display data to JTable

public void getAll(){ try { Registry regis = LocateRegistry.getRegistry("localhost", koneksi.Port_id ); remot rem = (remot) regis.lookup(koneksi.id); DefaultTableModel model=new DefaultTableModel(); for(mahasiswa mhs:rem.SelectMahasiswa()){ String kolom1=mhs.getNim(); String kolom2=mhs.getNama(); String kolom3=mhs.getJurusan(); String kolom[]={kolom1,kolom2,kolom3}; model.addRow(kolom); } jTable1.setModel(model); } catch (Exception ex) { ex.printStackTrace(); } }
