程序包 com.baomidou.mybatisplus.extension.injector.methods

类 AlwaysUpdateSomeColumnById

java.lang.Object
com.baomidou.mybatisplus.core.injector.AbstractMethod
com.baomidou.mybatisplus.extension.injector.methods.AlwaysUpdateSomeColumnById
所有已实现的接口:
com.baomidou.mybatisplus.core.toolkit.Constants, com.baomidou.mybatisplus.core.toolkit.StringPool, Serializable
public class AlwaysUpdateSomeColumnById extends com.baomidou.mybatisplus.core.injector.AbstractMethod
根据 ID 更新固定的那几个字段(但是不包含逻辑删除)

自己的通用 mapper 如下使用: 

 int alwaysUpdateSomeColumnById(@Param(Constants.ENTITY) T entity);

如何筛选字段参考请 InsertBatchSomeColumn 里面的注释
