其實在很早之前我就開發(fā)過一個博客系統(tǒng)藏斩，不過由于當時自己的技術不夠成熟据忘，所以選擇的是ssm+velocity開發(fā)蔗包。前后端沒有分離蛛壳，編輯器選擇是百度uedit寞缝，后臺使用的jQuery easyui,整個界面不是很美觀派敷，而且富文本編輯器很難用蛹批。所以一直想想給blog 升級。
現(xiàn)在 blog v2.0 beat即將上線篮愉。
它是基于 spring + vue實現(xiàn)的腐芍。

技術棧

• springboot 后臺基礎框架提供rest api接口

• springsecurity 提供安全權限認證

• jwt 提供訪問token

• spring-data-jpa 持久層訪問

• redis 提供數(shù)據(jù)緩存

• elasticsearch 提供全文檢索

• 七牛云 圖片托管至七牛云oss

• vue.js 前臺基礎框架

• iview 后臺管理ui
