这个错误是在从svn上下载下来的项目。。原来的项目使用的mysql是5.几的。现在的电脑上的mysql是8.几的，刚开始报错的数据库连接错误，pom中把数据库的驱动从5.1.47的改为8.0.11的之后，数据库能连接上。可是启动项目报上面的错误，清楚mysql是数据库
版本的问题，可是不能重新安装数据库吧，研究上面报的错，发现是数据连接的url 有问题，改了好几次没有什么效果。直接把能启动项目的url直接赋值过来就好了。。。很无语。。。。。不懂原理的痛。
把
jdbc.url=jdbc:mysql://localhost:3306/news?autoReconnect=true&useUnicode=true&characterEncoding=utf8&useSSL=true
改为
jdbc.url=jdbc:mysql://localhost:3306/news?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=CTT
