背景
遇到这个问题折腾好几个小时，差点被逼疯。记录一下。
先说下环境，MySQL数据库，表中字段名为update_time，类型为datetime。Java实体类中对应的变量是java.util.Date类型的updateTime。
环境交代完毕，使用update语句更新记录的时候，一直报错，说类型不匹配。贴上报错信息：

反复检查，数据库中的类型和Java实体类中的类型都没有错，缓存也清理了，都无效，一直就这个错。然后直接在逻辑层不更新这个时间了，只更新其他字段，结果没用，依旧报这个错！于是怀疑可能Mybaits Plus框架有问题，同事说可能会自动添加更新时间，可我在官网找半天也没找到相关描述。最后还是自己琢磨出解决办法了。下面附上解决方法：
方法一：
修改字段名为其他的，比如改成update_date或update_times
方法二：
字段名保持不变，将Java中的字段类型改为java.time.LocalDateTime，赋值的话LocalDateTime.now()即可。
原因猜测
个人还是觉得Mybaits Plus插件内部存在一个更新时间字段，导致冲突了。但没有证实。哪位大佬知道还请告知下。
Mybatis Plus 更新时间 updateTime字段报错 Could not set property 'updateTime'
