Java如何實(shí)現(xiàn)在線高中考試系統(tǒng)

這篇文章主要介紹了Java如何實(shí)現(xiàn)在線高中考試系統(tǒng)，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

項(xiàng)目分為前臺(tái)和后臺(tái)，前臺(tái)主要為學(xué)生角色、后臺(tái)主要為管理員角色。

管理員添加試題和發(fā)布試卷，學(xué)生負(fù)責(zé)在線考試、在線查看成績(jī)和錯(cuò)題記錄列表等。

管理員功能有：年級(jí)管理、課程管理、試題管理、試卷管理、學(xué)生管理等。

運(yùn)行環(huán)境：jdk1.8、mysql5.x、eclipse、tomcat8.5\7.0、maven3.5\3.6。
