1小時輕松上手springmvc,視頻網(wǎng)站后臺開發(fā)：由于最近半年一直在用springboot,但是也不能忘了本,于是把springmvc重新練了下，做了個前端傳個表單，后臺接收并顯示的界面，該項目可以上傳視頻的URL，然后前端進(jìn)行頁面的播放，項目采用springmvc+spring+mybatis,前端是用jquery.功能很簡單，前端一個form表單,提交后臺，后臺添加數(shù)據(jù)，并且將數(shù)據(jù)轉(zhuǎn)發(fā)到前端進(jìn)行顯示。后臺將entity,service,serviceimpl,controller,全部用marven進(jìn)行關(guān)聯(lián)，分模塊開發(fā)。
