ajax 传递集合

前端传值 
var conditons = [];
var order = app.orderList;
for (var i = 0; i < order.length; i++) {
    var list = [];
    var productId = order[i].id;
    var number = order[i].number;
    var deliveryType = order[i].flag;
    var remarks = order[i].remarks;
    list.push(productId);
    list.push(number);
    list.push(deliveryType);
    list.push(remarks);
    conditons.push(list);
}

data: {
    addrId: app.addr.id,
    conditons: JSON.stringify(conditons),
},

后端接收 

String conditons = getPara("conditons");

List<Object> list = JSONArray.parseArray(conditons);

这样就ok了
