每日代码

int officialShopId = shopId;
group.setShopId(officialShopId);
XmpUser xmpSeller = buildXmpUser(seller.getSellerInfo());
group.setSeller(xmpSeller);
List<XmpItem> xmpItems = buildXmpItemList(sellerList,clientName, officialShopId);
group.setItems(xmpItems);

以上代码看上去比较杂乱无章，可以做一个简单分组。

int officialShopId = shopId;
XmpUser xmpSeller = buildXmpUser(seller.getSellerInfo());
List<XmpItem> xmpItems = buildXmpItemList(sellerList,clientName, officialShopId);
                    
group.setShopId(officialShopId);  
group.setSeller(xmpSeller);
group.setItems(xmpItems);

这样就清晰很多，一方面可读性变好了，另一方面会便于进一步的重构，比如抽取小方法。

关于对象设置，C#的语法明显比java简洁多了。

group = new Group() { ShopId = officialShopId, 
                      Seller = xmpSeller,
                      Items = xmpItems
                    };

java下面可能用fluent API是种选择。

group.setShopId(officialShopId)
     .setSeller(xmpSeller)
     .setItems(xmpItems);
