仔细一想, 是我之前把Tenant 信息放到了redis 中, 然后,  重启了服务, 然后再次获取的时候, 就出现了这样的情况.

可以看到根本原因在于: 
local class incompatible: stream classdesc serialVersionUID = -6743567631108323096, local class serialVersionUID = -3998150864330771094

 

只需要在Tenant class 中增加下面的即可: 

private static final long serialVersionUID = -6743567631108323096L;
