Mybatis-Plus配置自动更新时间

Posted 2021-08-10 伍妖捌

配置代码

@Component
public class CustomMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        this.setFieldValByName("createTime", new Date(), metaObject);
        this.setFieldValByName("updateTime", new Date(), metaObject);
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        this.setFieldValByName("updateTime", new Date(), metaObject);
    }
}

使用

@ApiModelProperty(value = "创建时间", example = "2021-03-09 14:10:36")
@TableField(fill = FieldFill.INSERT)
private Date createTime;

@ApiModelProperty(value = "更新时间", example = "2021-03-09 14:10:36")
@TableField(fill = FieldFill.INSERT_UPDATE)
private Date updateTime;
