连接数据库报错：The last packet successfully received from the server was 67 milliseconds ago.

今天在阿里云上安装了一个mysql数据库，然后将本地代码的连接地址直接换成阿里云的地址，没想带连接报错：

报错信息：

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 67 milliseconds ago. The last packet sent successfully to the server was 65 milliseconds ago.

网上搜了不少都说了，连接超时问题，可是试了都不行，最后慢慢试错，发现是

&useSSL=false

这句导致的，原因如下：

是本地的jdbc与数据库不一致导致的。

有不少小伙伴反映，原本是true不行，改成false可以，大家可以尝试下
