我已经使用 create database dblife character set utf8 . 我用的是mysql版本 8.0.11 和mysql连接器版本 5.1.4 . 在下载mysql连接器之后，我已经替换了 .jar 文件与 Mysql.jar 内部 lib/ext 目录。所以，当我运行liferay服务器版本时 6.2 ，它给出如下错误。
在eclipse控制台上出现错误：

此外，我无法补充 portal-ext.properties 内部 liferay.home 目录。当我加上这个 portal-ext.properties 文件，然后我得到错误： Liferay v6.2(tomcat7 在localhost上遇到了一个问题。
我已经检查了现有的解决方案liferay不使用mysql，但是我看不到 Database Migration 控制面板>管理工具中的选项
谁能给我建议一个解决办法吗。我将非常感谢你。
