先說下原因，最近專案中出現了獲取網路資料混亂的情況，經過仔細檢視才知道是加入集合的順序出了問題，由於我是迴圈獲取id，然後再迴圈請求資料，請求成功之後就把實體類中的資料加入到ArrayList集合中，可是我忽略了網路請求的耗時不確定，可能第二次請求的耗時小於第一次請求，這就導致加入集合的順序不能保證，所以出現了錯亂，所以，我決定在加入集合後給他們排序。

經過查閱資料得知，解決的辦法有兩個，一個是通過Comparator，一個是實現Comparable介面，我在這裡選擇了第二種，使所在的類實現Comparable介面，重寫compareTo，和toString兩個方法。

呼叫非常簡單

 for (int i = 0; i < entity.getData().getDishes().size(); i++) {
                GoodsForTypeEntity goodsForTypeEntity = new GoodsForTypeEntity(typeId, typeName);
//                goodsForTypeEntity.setDishes_cate_id("" + dishes_cate_id);
setEntityParam(goodsForTypeEntity, entity.getData().getDishes().get(i));
                goodsList.add(goodsForTypeEntity);
      

            }
        }

        Collections.sort(goodsList);//只需要這一句就可以了
