Question

我用的是springmvc我想把Controller中的List传到前台去怎么传？ 前台怎么获取到list的值？

@RequestMapping(value="/address")
public String findaddress(){
ReceivedGoodsAddress receivedgoodsaddress=new ReceivedGoodsAddress();
List<ReceivedGoodsAddress> list = addressService.findReceivedGoodsAddress(receivedgoodsaddress);
return “jsp路径”
}

Answer 1

用@ResponseBody

    @RequestMapping(value = "/address", method = RequestMethod.POST)
    @ResponseBody
    public Map<String, Object> addressPOST() {
        Map<String, Object> map = new HashMap<>();
        ReceivedGoodsAddress receivedgoodsaddress=new ReceivedGoodsAddress();
        List<ReceivedGoodsAddress> list = addressService.findReceivedGoodsAddress(receivedgoodsaddress);
        map.clear();
        map.put("list", list);
        return map;
    }
    //前台用jquery+ajax
    $.ajax({
                type:'POST',
                url:'${contextPath}/address',
                dataType:'json',
                success:function(data){
                        $.each(data.list,function(i,item){
                            alert(i);
                            alert(item.id);
                            alert(item.name);
                        });
                }
            });
