java.lang.IllegalStateException: No typehandler found for property params

The XML location is 'file [E:\hzg_ecio_admin\ecio-system\target\classes\mapper\system\IotLogMapper.xml]'. Cause: java.lang.IllegalStateException: No typehandler found for property params

从上面报错信息可以看出是mybatis里面出错了，经检查代码是映射的地方出错。
