我想将数据批量导入数据库，而不是一一输入。
使用Sql Server的I / m用于数据库，使用Eclipse进行开发。
JScrollPane scroll = new JScrollPane(tableAsset);
JButton btnButton = new JButton("SELECT FILE");
btnButton.setFont(new Font("Verdana", Font.PLAIN, 13));
btnButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFileChooser fileopen = new JFileChooser();
FileFilter filter = new FileNameExtensionFilter("Text/CSV file", "txt", "csv", "xls", "xlsx");
fileopen.addChoosableFileFilter(filter);
int ret = fileopen.showDialog(null, "Choose file");
if (ret == JFileChooser.APPROVE_OPTION) {
// Read Text file
File file = fileopen.getSelectedFile();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
int row = 0;
while ((line = br.readLine()) != null) {
String[] arr = line.split(",");
dtm.addRow(new Object[0]);
dtm.setValueAt(arr[0], row, 0);
dtm.setValueAt(arr[1], row, 1);
dtm.setValueAt(arr[2], row, 2);
dtm.setValueAt(arr[3], row, 3);
dtm.setValueAt(arr[4], row, 4);
dtm.setValueAt(arr[5], row, 5);
dtm.setValueAt(arr[6], row, 6);
dtm.setValueAt(arr[7], row, 7);
dtm.setValueAt(arr[8], row, 8);
dtm.setValueAt(arr[9], row, 9);
dtm.setValueAt(arr[10], row, 10);
dtm.setValueAt(arr[11], row, 11);
dtm.setValueAt(arr[12], row, 12);
dtm.setValueAt(arr[13], row, 13);
dtm.setValueAt(arr[14], row, 14);
dtm.setValueAt(arr[15], row, 15);
dtm.setValueAt(arr[16], row, 16);
dtm.setValueAt(arr[17], row, 17);
dtm.setValueAt(arr[18], row, 18);
dtm.setValueAt(arr[19], row, 19);
dtm.setValueAt(arr[20], row, 20);
dtm.setValueAt(arr[21], row, 21);
dtm.setValueAt(arr[22], row, 22);
dtm.setValueAt(arr[23], row, 23);
dtm.setValueAt(arr[24], row, 24);
dtm.setValueAt(arr[25], row, 25);
dtm.setValueAt(arr[26], row, 26);
dtm.setValueAt(arr[27], row, 27);
dtm.setValueAt(arr[28], row, 28);
dtm.setValueAt(arr[29], row, 29);
dtm.setValueAt(arr[30], row, 30);
dtm.setValueAt(arr[31], row, 31);
dtm.setValueAt(arr[32], row, 32);
dtm.setValueAt(arr[33], row, 33);
dtm.setValueAt(arr[34], row, 34);
row++;
}
br.close();
} catch (IOException ex) {
ex.printStackTrace();
JOptionPane.showMessageDialog(null, ex);
}
lblResult.setText(fileopen.getSelectedFile().toString());
}
}
});
getContentPane().setLayout(null);
单击“导入”按钮时，将弹出另一个窗口来选择文件（文件可以是.txt，.csv，.xlx）
但是当我选择文件时，来自excel的实际数据没有显示在表中。而且它无法加载到数据库。
