mysql-JAVA SSH開發的網站後台部署到阿裡服務器時，連不上數據庫

JAVA SSH開發的網站後台部署到阿裡服務器時，連不上數據庫

現象
1）網站在自己的開發測試環境運行正常
2）在部署環境中，網站在訪問數據庫的時候，tomcat報錯如下：
另：開發環境跟部署環境的mysql的characterset不一樣（具體見下面的log），會導致這個問題嗎？

基本情況
1）部署環境
1.1）阿裡服務器操作系統： 32位，windows server standard
1.2）服務器上部署apache-tomcat-7.0.34
1.3）同一個服務器上安裝mysql服務器： 5.6.31（32位）//實在找不到哪裡有5.6.14可以下載
1.4）同一個服務器上用mysql訪問數據庫正常，端口，賬號，密碼都沒有問題

最佳回答：

嘗試了各種方法，最好重裝了一個mySql server，搞定
