ONLY_FULL_GROUP_BY 报错修改

show variables like 'sql_mode'; 

jdbc:mysql://192.168.xx.xx:3306/xxx_datesource?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&autoReconnect=true&maxReconnects=2&initialTimeout=1&failOverReadOnly=false&retriesAllDown=3&allowMultiQueries=true&sessionVariables=sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

应为在云服务器中,无法直接修改数据库配置,所以我们在JDBC中重新指定下。
