当前使用版本(必填,否则不予处理)
3.5.2
该问题是如何引起的？(确定最新版也有问题再提!!!)
1.实体类中定义了一个非数据库列的属性 2.Mapper xml文件中，重写getById 通过join 语句 链接出 userName 3.该属性无法通过LambdaQueryWrapper进行条件过滤，但是可以通过 QueryWrapper进行过滤
class Entity { @TableField(value = "user_name", exist = false) private String userName; }
重现步骤(如果有就写完整)

非指定为表字段的属性不会加入缓存

非指定为表字段的属性不会加入缓存
也就是说，非指定为表字段的属性 不能用在LambdaQueryWrapper里面？

指定了TableField也不行，大哭。。
