这是我的第一个类名 ConnectionDBClass.java 我想保存从数据库中检索数据，然后存储/显示到 JTable 中。
public class ConnectionDBClass implements Job {
public void execute(JobExecutionContext arg0) throws JobExecutionException {
String serverName = "192.168.0.1";
String portNumber = "1521";
String sid = "hifi";
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String username = "courser_hotline";
String password = "courser_hotline";
String[] columnNames = {"command_name", "omc_name", "to_module", "start_time", "end_time", "status", "priority", "cmd_id"};
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// System.out.println("Connecting to the database...");
Connection connection = DriverManager.getConnection(url, username, password);
Statement statement = connection.createStatement();
String query = "select command_name, omc_name, to_module, start_time, end_time, status, priority, cmd_id from sync_task_table";
// String query = "select * from sync_task_table";
ResultSet resultset = statement.executeQuery(query);
// Create some data
String dataValues[][] =
{
{ resultset.getString("command_name"), resultset.getString( "omc_name"), resultset.getString( "to_module"), resultset.getString("start_time"),resultset.getString("end_time"),resultset.getString("status"),resultset.getString("priority"),resultset.getString("cmd_id") }
};
//
//// Create a new table instance
GUIClass.table = new JTable( dataValues, columnNames );
}
catch (Exception e) {
System.out.println("The exception raised is:" + e);
}
}
}
这是我的第二个类名 GUIClass.java 在这个类中 GUI 的代码
public class GUIClass extends JFrame {
static JFrame frame;
static JLabel formlabel;
static JPanel panel1;
static JPanel panel2;
static JTextField t1;
static JComboBox selectOMC;
static JButton run;
static JPanel panel3;
static DefaultTableModel model;
public static JTable table;
static JScrollPane tableScroll;
static Dimension tablePreferred;
public static void createGUI()
{
InilizationAndLabelGUIVariables.Initilization();
InilizationAndLabelGUIVariables.LabelForm();
}
public static void main(String[] args)
{
createGUI();
}
}
我的第三个类名是 InilizationAndLabelGUIVariables.java 在这个类中初始化并标记在 GUIClass.java 类中声明的变量
public class InilizationAndLabelGUIVariables {
public static void Initilization()
{
GUIClass.frame = new JFrame("Syncronization Optimizer");
GUIClass.panel1 = new JPanel(new BorderLayout(5,5));
GUIClass.panel2 = new JPanel(new FlowLayout(FlowLayout.RIGHT, 3,3));
GUIClass.formlabel = new JLabel("Syncronization Optimizer Tool");
GUIClass.t1 = new JTextField(23);
GUIClass.selectOMC = new JComboBox(ConnectionDB.OMCName);
GUIClass.run = new JButton(" Run ");
GUIClass.panel2 = new JPanel();
GUIClass.model = new DefaultTableModel(ConnectionDBClass.dataValues, ConnectionDBClass.columnNames);
GUIClass.table = new JTable(GUIClass.model);
try {
// 1.6+
GUIClass.table.setAutoCreateRowSorter(true);
} catch(Exception continuewithNoSort) {
}
GUIClass.tableScroll = new JScrollPane(GUIClass.table);
GUIClass.tablePreferred = GUIClass.tableScroll.getPreferredSize();
GUIClass.tableScroll.setPreferredSize(
new Dimension(GUIClass.tablePreferred.width, GUIClass.tablePreferred.height/3) );
GUIClass.frame.setContentPane(GUIClass.panel1);
GUIClass.frame.setBounds(150,100,570,491);
GUIClass.frame.setResizable(false);
GUIClass.frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
GUIClass.frame.setVisible(true);
}
public static void LabelForm()
{
GUIClass.panel1.add(GUIClass.panel2, BorderLayout.NORTH);
GUIClass.panel2.add(GUIClass.formlabel);
GUIClass.panel2.add(GUIClass.selectOMC);
GUIClass.panel1.add(GUIClass.tableScroll);
GUIClass.panel2.add(GUIClass.table);
// gui.add( splitPane, BorderLayout.CENTER );
}
}
请帮助我，我坚持这样做。
