Answer 1

at org.jb.y272.team0.action.CustomerAction.toList2(CustomerAction.java:84)

Answer 2

public ActionForward toList2(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
CustomerForm myForm = (CustomerForm)form;
List list = this.customerBiz.getConsList(myForm.getType());
request.setAttribute("list", list);
return mapping.findForward("cons_rpt_list");

Answer 3

List list = this.customerBiz.getConsList(myForm.getType());
这行代码错误了.  getConsList(); 这个方法可以看看么 .估计你查询的HQL 语句出错了

at org.jb.y272.team0.biz.CustomerBiz.getConsList(CustomerBiz.java:158)getConsList方法有问题，debug跟踪下嘛

Answer 5

public List getConsList(String type){
String hql = "";
if ("按等级".equals(type)){
hql = "select custLevelLabel,COUNT(c) from CstCustomer c where c.custStatus=1 " +
"group by c.custLevel,custLevelLabel ";
}else if ("按信用度".equals(type)){
hql = "select c.custCredit,COUNT(c) from CstCustomer c where c.custStatus=1 " +
"group by c.custCredit ";
}else if ("按满意度".equals(type)){
hql = "select c.custSatisfy,COUNT(c) from CstCustomer c where c.custStatus=1 " +
"group by c.custSatisfy ";
}
return this.getCommonDAO().list(hql);
}
