好像是这个类 com.flower.
www.webtier.CustomerInfoController 实例化失败，遇到了空指针问题。
package com.flower.www.webtier;
import java.io.IOException;
import java.util.List;
import javax.servlet.http.HttpServlet;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;

public class CustomerInfoController {
private CustomerInfoFacade customerInfoFacade;
private int controlMethod;
public CustomerInfoController() {
customerInfoFacade = new CustomerInfoFacadeImpl();
}
private void selectCustomerInfo(HttpServletRequest request, HttpServletResponse response) throws IOException ,ServletException {
CustomerInfo customerInfo = new CustomerInfo();
List customerInfoList = customerInfoFacade.selectCustomerInfo(customerInfo);
request.setAttribute("customerInfoList", customerInfoList);
RequestDispatcher requestDispatcher = request.getRequestDispatcher("/customerFind.jsp");
requestDispatcher.forward(request, response);
}
private void insertCustomerInfo(HttpServletRequest request, HttpServletResponse response) throws IOException ,ServletException {
CustomerInfo customerInfo = new CustomerInfo();
customerInfo.setCustomerName(request.getParameter("customerName"));
customerInfo.setAge(Integer.valueOf(request.getParameter("age")));

customerInfo.setDate(request.getParameter("date"));

customerInfo.setG3(Integer.valueOf(request.getParameter("g3")));
customerInfo.setG4(Integer.valueOf(request.getParameter("g4")));
customerInfo.setG5(Integer.valueOf(request.getParameter("g5")));
customerInfoFacade.insertCustomerInfo(customerInfo);
//selectCustomerInfo(request, response);
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException ,ServletException {
request.setCharacterEncoding("gb2312");
controlMethod = Integer.parseInt(request.getParameter("controlMethod"));
switch(controlMethod) {
case 0:{
this.selectCustomerInfo(request, response);
break;
}
case 1:{
this.insertCustomerInfo(request, response);
break;
}
case 2:{
this.updateCustomerInfo(request, response);
break;
}
case 3:{
this.deleteCustomerInfo(request, response);
break;
}
case 4:{
this.findCustomerInfo(request, response);
break;
}
}
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException ,ServletException {
doGet(request, response);
}
}
这是CustomerInfoController类的基本情况，可能是哪出问题了呢？
