大項目之網上書城（三）——主頁（中）
目錄
盡量日更，我發現我還要寫的東西有好多啊。
主要改動
設計這個勉強看得過去的顏色，填充之前的主頁，按照之前的思路，左邊是圖書分類，中間一個輪播圖，然后右邊是一個文案廣告，加一個熱銷書推薦，下面是新書推薦，然后下面的右面是新書排行榜。因為我打算把網頁弄成動態的，於是熱銷書推薦，新書推薦，新書排行榜，都要是通過js+servlet來從數據庫獲取最新數據，寫起來會非常麻煩啊。（以及我還沒有數據庫，我還沒有dao，沒有BookBean，沒有service，於是測試起來超麻煩啊。就只給熱銷書推薦寫了個簡單的測試。新書推薦因為涉及到圖片，我不太了解，還在發展科技樹，真的很艱巨啊。再加上我意識到我要設計一下通用的圖書詳情頁面，我要增加個超級用戶。超級用戶要可以修改數據庫，啊，真的好難啊。任重而道遠。）
1.主頁持續施工中
