从HashMap在页面上动态取值

for(BmAccountDtl dtl:dtlList){
   if(StringUtils.isNotBlank(dtl.getOrderNo())){
    BmOrder order = bmOrderService.getBmOrderByOrderNo(dtl.getOrderNo());
    if(StringUtils.isNotBlank(order.getBankOrderNo())){
     map.put(order.getOrderNo(), order.getBankOrderNo());

//action中给map放值 key是orderNo,value是bankOrderNo
     System.out.println("orderNo="+order.getOrderNo()+"    bankOrderNo="+order.getBankOrderNo());
    }
   }
  }

 

<c:set value="${bmAccountDtl.orderNo}" var="orderNo"></c:set>
          <c:forEach items="${map}" var="m">
            <c:if test="${m.key==orderNo}">
             ${m.value }  这个就是与当前orderNo对应的value值
            </c:if>
          </c:forEach>

页面上取值orderNo是变化的
