注意看上邊報錯信息中的紅色字體部分，剛開始出現這個錯誤的時候我復制報錯信息在百度上各種搜，結果答案都不對，后來請教我們項目組的大神，單獨復制的紅色字體部分去百度一搜就出來了相應的答案，所以說，報錯信息一大堆未必都有用，找到關鍵點才是解決錯誤的關鍵，在通過本篇文章解決錯誤之前，應先確定MyBatis配置文件中的數據庫名、用戶名、密碼都正確，打開CMD輸入 mysql -u [用戶名] -p 回車后輸入密碼，以判斷密碼是否正確，建議先把數據庫配置一下環境變量，否則通過cmd命令打開的數據庫的時候還要切到mysql文件下的bin目錄下才行，太麻煩，關於配置數據庫環境變量的教程百度一搜一大堆，這里就不一一闡述了，回歸正題：

解決步驟：

1. 打開MySQL目錄下的my.ini文件，若找不到數據庫安裝目錄也可以全局搜索 my.ini，用記事本打開即可，在[mysqld] 標簽下添加“skip-grant-tables”，保存並關閉文件，如圖：
2. 通過services.msc命令進入本地服務列表，重啟MySQL服務。
3. 通過命令行進入MySQL的BIN目錄（若已經配置過環境變量直接輸入“mysql -u root -p”即可），輸入“mysql -u root -p”(不輸入密碼)，回車即可進入數據庫。
4. 執行“use mysql;”，使用mysql數據庫。
5. 執行“update user set password=PASSWORD(“password”) where user=’root’;”（修改root的密碼），這里要格外說一下，因為我的數據庫是新版的，所以用剛才的命令修改是報ERROR的，行不通，只能通過下面命令進行修改，這里被坑了好久，“update mysql.user set authentication_string=password('password') where user='root' and Host = 'localhost';”
6. 打開MySQL目錄下的my.ini文件，刪除最后一行的“skip-grant-tables”，保存並關閉文件.
7. 通過services.msc命令進入本地服務列表，重啟MySQL服務。

8. 在命令行中輸入“mysql -u root -p”，回車輸入“password”即可成功連接數據庫。

9. 上述步驟完事之后本以為可以成功連接了，卻沒想到又出現了新的錯誤，先上報錯信息看一下：Thu Mar 22 16:06:58 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
10. 百度一搜，只需要改一下MyBatis配置文件中的url即可，改后如圖：

    url: jdbc:mysql://localhost:3306/user?useSSL=false&useUnicode=true&characterEncoding=UTF-8

11. 好了，程序正常運行，本人剛入行不久，小菜鳥一枚，哪里有不對的，還請各位大神們多多指教，不勝感激！
