错误信息:
2020-04-17 08:43:28,810 [http-nio-443-exec-8] ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] - Packet for query is too large (1673 > 1024). You can change this value on the server by setting the max_allowed_packet‘ variable.
当查询数据比较大的时候在网络中传输，超过默认值就会报以上错误
解决方法,找到mysql配置文件.my.ini,在[mysqld]下面添加以下配置
max_allowed_packet = 100M
query_cache_limit = 40M
