Question

从Servlet里边读取数据到页面为什么会打印出我不需要的数据啊

List list=ReportDetaildaoImpl.GetReportDetailList(userid);//得8条数据
for (int i = 0; i <list.size(); i++) {
ReportDetail rdt=(ReportDetail)list.get(i);
if(list.size()-1==i)
str+="702|TradeStore|"+pageNO+"|总页数|"+rdt.getOrderCode()+"|"+rdt.getCompanyname()+"|状态|"+rdt.getOType()+"|"
+rdt.getNum()+"|"+rdt.getPrice()+"|"+rdt.getTDate()+"|加码|"+rdt.getEndPrice()+"|涨跌|"+rdt.getTTime()+"|成交时间|下单总类|删单|浮动盈亏";
else
str+=str+="702|TradeStore|"+pageNO+"|总页数|"+rdt.getOrderCode()+"|"+rdt.getCompanyname()+"|状态|"
+rdt.getOType()+"|"+rdt.getNum()+"|"+rdt.getPrice()+"|"+rdt.getTDate()+"|加码|"+rdt.getEndPrice()+"|涨跌|"+rdt.getTTime()+"|成交时间|下单总类|删单|浮动盈亏@";
}

request.setAttribute("Reportdt", str);
RequestDispatcher rs=request.getRequestDispatcher("/ReportDatailServlet.jsp");
rs.forward(request, response);//执行这里之后jsp页面就显示无数条数据

Answer 1

死循环吗？至少if、else后面就算空语句也要加对正反大括号吧

Answer 2

代码 看看啊
