本文將采用SpringBoot+Spring+Mybatis+Thyeleaf實(shí)現(xiàn)一個(gè)課程在線學(xué)習(xí)系統(tǒng)，采用SpringBoot框架實(shí)現(xiàn)?前臺(tái)模板用的thymeleaf數(shù)據(jù)庫(kù)層采用mybatis框架注解模式，感興趣的可以了解一下

一、前言

項(xiàng)目介紹

采用SpringBoot+Spring+Mybatis+Thyeleaf實(shí)現(xiàn)的在線學(xué)習(xí)系統(tǒng)，一共2個(gè)身份。

管理員登錄系統(tǒng)后可以管理所有用戶信息，管理角色信息，添加修改管理課件信息，學(xué)生學(xué)習(xí)培訓(xùn)批次管理，成績(jī)導(dǎo)入管理

學(xué)生登錄系統(tǒng)后可以查詢自己的個(gè)人信息，查詢課件列表學(xué)習(xí)，查詢我的培訓(xùn)記錄，查詢自己的成績(jī)

采用SpringBoot框架實(shí)現(xiàn) 前臺(tái)模板用的thymeleaf 數(shù)據(jù)庫(kù)層采用mybatis框架注解模式
