idea鏈接mysql數據庫見下面參考鏈接1，需要注意的一點，如果數據庫沒有設置全局的serverTimeZone這里報錯，然后去哪個設置頁面Advanced那里把該項寫為Asia/Shanghai就ok,idea連接后可以在右側看到如圖所示效果

然后嘗試連接后並未解決問題（尷尬XD 這步只是起到了數據庫連接工具，感覺這個功能集成了datagrip的一些特性），再找其他方法
關鍵報錯是這句話：

參考鏈接2也列了幾種可能得錯誤。。。也不是
參考鏈接3終於解決，算是一個非常低級的錯誤。。。寫SqlMapConfig.xml的時候
錯誤寫法

<property name="url" value="jdbc:mysql//localhost:3306/mybatis_test"/>

正確寫法,注意有冒號。。。

<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test"/>

算是一個教訓，也是一個no suitable driver found for jdbc的一個解決匯總

另外，如果數據庫沒有設置全局serverTimeZone，這里還可能報個錯，一個簡單的解決是在url后?加上一些參數（包括時區）

<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT"/>

還有一個地方注意，xml中的&必須寫為&否則這里報錯

再改：

<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test?useUnicode=true&amp;characterEncoding=utf8&amp;serverTimezone=GMT"/>

到這里我出現的關於idea數據庫，以及mybatis數據庫配置出現的問題全部解決，小結如下：

• mybatis出現就是為了解決jdbc配置問題，讓使用者更加專注於問題本身，但是配置過程需小心（也是我不熟悉配置的原因，use it or lose it，慢慢熟悉）
• 配置文件SqlMapConfig.xml中url需要注意"mysql:"的":"
• xml文件中的";"需要用"&"代替
