1、报错信息

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: In aggregated query without GROUP BY, expression #2 of SELECT list contains nonaggregated column 'd.total_rated_power_transformer'; this is incompatible with sql_mode=only_full_group_by

2、修改配置文件

（1）找到配置文件my.cfg

 find / -name "my.cnf"

（2）修改配置文件

 vi /etc/my.cnf

加一行
sql_mode=STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION如果原本有sql_mode，去掉ONLY_FULL_GROUP_BY

3、重启mysql使配置生效

service mysqld restart
