Java開(kāi)發(fā)旅游網(wǎng)站

Java小項(xiàng)目之：旅游網(wǎng)站
旅游網(wǎng)站應(yīng)用到的技術(shù)：
1．Hibernate
2．Tomcat Servlet
3．Jsp，javaScript，jquery , Ajax,EL表達(dá)式

前臺(tái)功能：
1用戶(hù)的注冊(cè)和登錄，
2旅游線路的報(bào)名（一人只能報(bào)一條線路）；
3用戶(hù)對(duì)每條旅游線路的評(píng)論。
4查詢(xún)一個(gè)城市的所有線路
5查詢(xún)單一的一條線路

后臺(tái)管理功能：
1旅游線路的增刪改查
2對(duì)用戶(hù)評(píng)論的刪除或回復(fù)
3刪除查詢(xún)用戶(hù)
