Caused by: com.fasterxml.jackson.databind.JsonMappingException:
No serializer found for class
com.xiaojukeji.epower.atreus.common.base.vo.smartcharging.order.OrderManagerVO and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.xiaojukeji.epower.component.Response["data"]->com.baomidou.mybatisplus.extension.plugins.pagination.Page["records"]->java.util.ArrayList[0])

问题原因:

实体lombok注解@Accessors(chain = true)中fluent=true不要使用,不然在spring内部转json时会报以上错误
另外最近使用easyexcel导出时也出现的诡异问题
easyexcel实体使用Accessors注解会无法读取数据

建议干脆别用这个注解了,问题太特么多了。心累。用Builder就可以了
