Question

Unresolved compilation problems:

代码如下:
public class InfoAction extends Action {
JDBConection jdbc=new JDBConection();
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)throws Exception {
JspInfoForm newForm=(JspInfoForm) form;
List list2=new ArrayList();
int userID=newForm.getUserID();
String loginName=newForm.getLoginName();
String passWord=newForm.getPassWord();
newForm.setUserID(userID);
newForm.setUserName(userName);
newForm.setLoginName(loginName);
newForm.setPassWord(passWord);
list2.add(newForm);
InfoAction ina=new InfoAction();
if(request.getParameter("submit").equals("add")){
ina.update(userID,list2);
}else if(request.getParameter("submit").equals("change")){
ina.insert(list2);
}else if(request.getParameter("submit").equals("delete")){
ina.Delete(userID);
}
return mapping.findForward("err");
}
public ActionForward update(int userID,List list2){

List list=jdbc.selectDb();
for(int i=0;i<list.size();i++){
JspInfoForm info=(JspInfoForm)list.get(i);
if(userID==info.getUserID()){
jdbc.deleteDb(userID);
jdbc.insertDb(list2);
jdbc.selectDb();
List list3=jdbc.selectDb();
int infoNumber=list3.size();
ServletRequest request = null;
request.setAttribute("list",list3);
ActionMapping mapping = null;
return mapping.findForward("suc");
}
}
ActionMapping mapping = null;
return mapping.findForward("err");
}
public ActionForward insert(List list2){
jdbc.insertDb(list2);
jdbc.selectDb();
List list3=jdbc.selectDb();
int infoNumber=list3.size();
ServletRequest request = null;
request.setAttribute("list",list3);
ActionMapping mapping = null;
return mapping.findForward("suc");
}
public ActionForward Delete(int userID){
jdbc.deleteDb(userID);
jdbc.selectDb();
List list=jdbc.selectDb();
ServletRequest request = null;
request.setAttribute("list",list);
ActionMapping mapping = null;
return mapping.findForward("suc");
}
}
报错如下:

你的构造函数错了吧，少了个分号

Answer 2

哪个地儿少了个分号。用eclipse吧有语法检查

Answer 3

Action类貌似没问题，检查一下你的struts配置有没问题
