环境

java: 1.8.0_131
hsweb: 3.0.5

问题说明

因为有一个字段是 progress，前端走的更新 updateById，希望能避免前端传值更新到此字段。
后台有任务单独对这个 progress 单独维护。

尝试过设置 @Column(updatable = false)，但这样 createUpdate() 也无法进行更新

方式一： 重写接口方法，实体类设置为null
方式二：监听 EntityPrepareModifyEvent 通过上下文判断是否可以更新某个字段。如果不能，就将after的字段设置为before的字段。

感谢回复，是否考虑增加类似mbp的updateStrategy=NOT_NULL来控制呢

update本身会忽略null值。 目前两种方式其实都是走createUpdate。后续看能否通过上下文传递强制更新。
