List转化为Map

                 List<JfAuction> jfAuctionListValue=new ArrayList<JfAuction>();
                 Map<Integer, JfAuction> jfAuctionMap = new HashMap<Integer, JfAuction>();
                   for (Integer key : jfAuctionMap.keySet()) {
                        jfAuctionListValue.add(jfAuctionMap.get(key));
                }
