物业未找到！相同的命名惯例

Question

我在这里再问一个问题，我前一段时间尝试过这个问题（今天），但我已经重建了我的代码。所以，我的问题是，当我单击按钮显示数据库中的详细信息时，它显示一个错误，找不到属性，我很困惑为什么会出现这个错误，这是一个错误的例子，如我可以看到它可以在我输出数据库时读取数据库中的元素，并在控制台中显示它pic of error    ）

     //empServlet
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
{
    empServices empserv= new empServices();
    ArrayList <empGetSet> empgs = new ArrayList<empGetSet>();

    if (request.getParameter("process")!=null &&  request.getParameter("process").equals("showdis")) {

        empgs.addAll(empserv.getAll());
        request.setAttribute("empdet", empgs);
        RequestDispatcher rd = request.getRequestDispatcher("showdet.jsp"); //forward to xxxpage after submit by button
        rd.forward(request,response);

    }

       //empServices
 package emppackage;

 import java.util.ArrayList;

 public class empServices {

empServlet empservlet = new empServlet();
empDAO empdao = new empDAO();
public ArrayList <empGetSet> getAll() 
    {
        return empdao.getAllEmp();

    }

     //empDAO
    public ArrayList<empGetSet> getAllEmp()
  {

ArrayList<empGetSet> empdetails = new ArrayList<empGetSet>();

try {

    Connection conn = getConnection();
    String showsql = "SELECT *FROM csemp;";
    PreparedStatement psread= conn.prepareStatement(showsql);
    ResultSet rsread = psread.executeQuery();

    while (rsread.next()) 
    {

        empGetSet readgetset = new empGetSet();

        readgetset.setFname(rsread.getString(1));
        //System.out.println(readgetset.getFname());
        System.out.println(rsread.getString(1));
        readgetset.setLname(rsread.getString(2));
        readgetset.setNameRes(rsread.getString(3));
        readgetset.setSerials(rsread.getString(4));
        readgetset.setJrss(rsread.getString(5));
        readgetset.setBand(rsread.getString(6));
        readgetset.setAcct(rsread.getString(7));
        readgetset.setPMPs(rsread.getString(8));
        readgetset.setsJRSS(rsread.getString(9));
        readgetset.setOpenSeatDesc(rsread.getString(10));
        readgetset.setReqSkills(rsread.getString(11));
        readgetset.setReqBand(rsread.getString(12));
        readgetset.setDreject(rsread.getString(13));
        readgetset.setsRreject(rsread.getString(14));
        readgetset.setDetActPlan(rsread.getString(15));
        readgetset.setDataComplete(rsread.getString(16));
        readgetset.setStat(rsread.getString(17));


        empdetails.add(readgetset);

    }
    psread.close();
    conn.close();

}


catch (Exception e)
{

    e.printStackTrace();
}



return empdetails;


 }

这是我的Getters和Setters，具有相同的命名约定 package emppackage;
