Iterator<ReplenishmentReportVO> itreator=missingStockProducts.iterator();

while(itreator.hasNext()){
//不可以多次调用.next()方法
    ReplenishmentReportVO next=itreator.next();
    if(pageRecordListMap.containsKey(next.getProductId())&&pageRecordListMap.get(next.getProductId())==next.getAdviceReplenishNum()){
        itreator.remove();
