基于java的旅游推薦系統(tǒng)設計與實現
一、前言
在設計旅游推薦系統(tǒng)時，功能模塊充分融合了用戶與管理員的實際需求，實現了多元化且全面的服務功能。用戶端功能涵蓋景點瀏覽、購票服務、旅游新聞獲取、公告信息等，并融入了基于協(xié)同過濾算法的個性化智能推薦，為用戶提供量身定制的旅游建議。此外，系統(tǒng)還提供了注冊登錄、個人收藏夾、在線留言等個性化與便捷功能，進一步提升了用戶體驗。管理員端則包括賬號管理、地區(qū)維護、景點信息管理、訂單處理、新聞發(fā)布等功能，旨在提升管理效率。推動旅游業(yè)的現代化發(fā)展與管理進步。通過明確的功能模塊劃分，系統(tǒng)確保用戶與管理員能夠輕松達成各自目標，同時保障了系統(tǒng)的高效運作與卓越的用戶體驗。
二、系統(tǒng)功能設計
?三、系統(tǒng)實現
如圖5.1顯示的就是用戶信息管理頁面，此頁面提供給管理員的功能有：用戶信息的查詢管理，可以刪除用戶信息、修改用戶信息、新增用戶信息，
還進行了對用戶名稱的模糊查詢的條件
圖5.1 用戶信息管理頁面
如圖5.2顯示的就是景點信息管理頁面，此頁面提供給管理員的功能有：查看已發(fā)布的景點信息數據，修改景點信息，景點信息作廢，即可刪除，還進行了對景點信息名稱的模糊查詢 景點信息信息的類型查詢等等一些條件。
圖5.2 景點信息管理頁面
如圖5.4顯示的就是公告信息管理頁面，此頁面提供給管理員的功能有：根據公告信息進行新增、修改、查詢操作等等。
圖5.4 公告信息管理頁面
