mybatisplus 更新字段

Mybatis Plus在进行更新操作时，默认情况下是不能将字段更新为null的。如果要更新字段为null，需要进行以下处理。首先，需要在需要更新的字段上加上@TableField注解，并设置属性updateStrategy=FieldStrategy.IGNORED。这样，Mybatis Plus在更新操作时就会忽略该字段的值，从而可以将其更新为null。此外，也可以手动编写更新SQL语句，通过使用set语句将字段更新为null。总之，要更新字段为null，需要进行相应的注解设置或手动编写更新SQL语句。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
