最近做起了這個項目，本人覺得這個項目相當有研究價值，值得學習。記錄一下遇到的問題及解決方法。
第一天：
問題1：Lombok沒有裝插件，雖然引入依賴，還是導致set/get無效。去Settings/Plugins/搜索Lombok安裝，重啓idea即可。
問題2：想導入heima-leadnews.sql，
先創建數據庫：要注意編碼：有些沒有這個選項，那就要找出問題，我的mysql5.7。Navicat12。
![]()
接下來導入sql文件，注意編碼：
![]()
第二天
在導入bak.sql時會報錯，如果沒有導，那麼恭喜你：趕緊去設置變量，要進入mysql控制檯。
mysql>set global max_allowed_packet=1024*1024*1024;
查一下變了沒，之間是4開頭的，現在多了好多位。忘記截圖了。
mysql> show global variables like 'max_allowed_packet';
這樣就可以順利導入，不報錯。我是報了錯才找到解決方法，對了，我的數據庫是解壓版，不是安裝版。
如果不小心導入了，出錯了，那麼就是刪除數據庫，那真的是多，有什麼辦法呢？有呀，只要百度就有。
![]()
直接上刪庫語句更好

接下來，啓動mysql，導入 bak.sql文件
![]()
大功告成。OK
在連接MyCat 8066時，反正表看不全，還沒有想到好的辦法，刷一下，幾張表，再刷一下十幾張表，不知道怎麼弄，正在思考當中，但做測試ap_article沒問題。目前只到了第二天的第18個視頻。
