当我点击保存按钮时我有内部jframe 员工列表和jdialog AddEditEmployee 我希望员工列表中的刷新jtable 然后 AddEditEmployee 已清除。
我正在尝试在保存按钮actionListener中调用 isTableModel 方法，但它不起作用。
请参阅下面的screenshot here和代码：
员工控制器
public class EmployeeController {
private EmployeeList employeeList_view;
private AddEditEmployee addEditEmployee_view;
private ImplementEmployeeList implementEmployeeList;
private List<Employees> employees;

implementEmployeeList = new EmployeeDAO();
employees = implementEmployeeList.getEmployeeList();
}
public EmployeeController(AddEditEmployee addEditEmployee_view){
this.addEditEmployee_view = addEditEmployee_view;
implementEmployeeList = new EmployeeDAO();
employees = implementEmployeeList.getEmployeeList();
}
public void reset(){
addEditEmployee_view.getJtfEmployeeID().setText("");
addEditEmployee_view.getJtfFirstName().setText("");
addEditEmployee_view.getJtfLastName().setText("");
}
public void isTableModel(){
employees = implementEmployeeList.getEmployeeList();
EmployeeTableModel employeeTableModel = new EmployeeTableModel(employees);
employeeList_view.getJtbEmployeeList().setModel(employeeTableModel);
}
public void insert(){
Employees emp = new Employees();
Functions func = new Functions();
emp.setEmployee_code(Integer.parseInt(addEditEmployee_view.getJtfEmployeeID().getText()));
emp.setFirst_name(addEditEmployee_view.getJtfFirstName().getText());
emp.setLast_name(addEditEmployee_view.getJtfLastName().getText());
emp.setGender(addEditEmployee_view.getJcbGender().getSelectedItem().toString());
emp.setDate_of_birth(addEditEmployee_view.getDateOfBirth().getDate());
emp.setHire_date(addEditEmployee_view.getHireDate().getDate());
emp.setMarital_status(addEditEmployee_view.getJcbMaritalStatus().getSelectedItem().toString());
emp.setPhoto(func.convertBufferedImageToBlob(addEditEmployee_view.getJlbPhoto()));
implementEmployeeList.insert(emp);
}
public void update(){
Employees emp = new Employees();
//emp.setEmployee_code(Integer.parseInt(addEditEmployee_view.getJtfEmployeeID().getText()));
emp.setFirst_name(addEditEmployee_view.getJtfFirstName().getText());
emp.setLast_name(addEditEmployee_view.getJtfLastName().getText());
emp.setGender(addEditEmployee_view.getJcbGender().getSelectedItem().toString());

emp.setHire_date(addEditEmployee_view.getHireDate().getDate());
emp.setMarital_status(addEditEmployee_view.getJcbMaritalStatus().getSelectedItem().toString());
implementEmployeeList.update(emp);
}
public void delete(){
implementEmployeeList.delete((Integer) employeeList_view.getJtbEmployeeList().getValueAt(employeeList_view.getJtbEmployeeList().getSelectedRow(),1));
}
} 员工TableModel
