This article mainly introduces how to solve the problem that MybatisPlus modifies the spatio-temporal field without modification, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

Problem description:

A problem encountered today is that when updating data, MybatisPlus does not modify datasheet fields whose properties are empty.

Solution:

You only need to add a line of comments to the attributes of the entity class

/ * * name * / @ TableField (fill = FieldFill.UPDATE) private String name

This line of comments means that when the name property is modified, a value (the default is null) is automatically populated, which means that the field is changed to empty rather than left unmodified.
