最近很郁悶，一個女粉絲找我要開發一個系統。說是很著急。
?
但是費用不高，說自己沒錢。
?
我平時事也很多，又不是很想接。
?
說了一大堆苦情的話，然后說自己的要求不高，沒有ui要求，
?
我就接了。
?
但是后來，越扯越嚴重……上升到600塊要開發一個知乎的高度。這讓我想起了預算茅草屋的價格，想要別墅的效果。

?
扯皮扯的很累，項目我已經遠程調試好了，也講解了。最后全部退款了。
?

?
關鍵是我還整理了很多講解的說明：

?

?

既然退款，項目就不是你的了，我開發的就是我的，項目的源碼就開源吧。

兄弟們，給個三連安慰下我。源碼是你們的了。在文章底部。

首先看一下這個項目演示，值不值600塊？評論區告訴我

一，系統演示

?

二，系統的簡介

開發語言：Java

框架：ssm

JDK版本：JDK1.8

服務器：tomcat7

數據庫：mysql 5.7（一定要5.7版本）

數據庫工具：Navicat11

開發軟件：eclipse/myeclipse/idea

Maven包：Maven3.3.9

瀏覽器：谷歌瀏覽器

二，系統實現的主要功能

（1）用戶管理。主要實現了仿知乎微信小程序的用戶管理功能。

（2）標簽管理。主要實現了仿知乎微信小程序的標簽管理功能。

（3）今日熱聞管理。主要實現了仿知乎微信小程序的今日熱聞管理功能。

（4）問答模式管理。主要實現了仿知乎微信小程序的問答模式管理功能。

（5）文件管理。主要實現了仿知乎微信小程序的文件管理功能。

四，源碼獲取

這個項目搞的恨不痛快，以后這樣的再也不接了。開始的時候就要確認好需求。源碼給你了。
