为相关字段配置触发填充的时机，例如create_time需要在插入数据时填充，而update_time需要在更新数据时填充。具体配置如下，观察@TableField注解中的fill属性。

@Data
public class BaseEntity {

    @Schema(description = "主键")
    @TableId(value = "id", type = IdType.AUTO)
    private Long id;

    @Schema(description = "创建时间")
    @JsonIgnore
    @TableField(value = "create_time", fill = FieldFill.INSERT)
    private Date createTime;

    @Schema(description = "更新时间")
    @JsonIgnore
    @TableField(value = "update_time", fill = FieldFill.UPDATE)
    private Date updateTime;

    @Schema(description = "逻辑删除")
    @JsonIgnore
    @TableLogic
    @TableField("is_deleted")
    private Byte isDeleted;

}

配置自动填充的内容，具体配置如下在common模块下创建MybatisMetaObjectHandler类，内容如下：

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

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