mybatis手写insert跟update重写mybatis的handle方法设置默认值不生效

java 复制代码

@Data
@Accessors(chain = true)
@TableName("mrp_flowmeter")
public class MrpFlowmeter implements Serializable {

    private static final long serialVersionUID = 1L;

    @TableId(value = "water_meter_id", type = IdType.ID_WORKER_STR)
    private String waterMeterId;
	
    @TableField(value = "enterprise_Id",fill = FieldFill.INSERT)
    private String enterpriseId;
    
    @TableField(value = "create_uid",fill = FieldFill.INSERT)
    private String createUid;
    
    @TableField(value = "create_time",fill = FieldFill.INSERT)
    private Date createTime;

    @TableField(value = "modify_uid",fill = FieldFill.INSERT_UPDATE)
    private String modifyUid;
    
    @TableField(value = "modify_time",fill = FieldFill.INSERT_UPDATE)
    private Date modifyTime;
}

我在service类里调用mapper类的insert跟update类操作数据之后，通用mybatis的自动生成值的方法，没有设置默认值。

原因在mapper层的方法参数里我加了@param()，我重写的mybatis的Handler类设置生成id，生成创建人修改人没有生成值。应该把@param()去掉。

sql 复制代码

//正确
Integer insertBatchMrpFlowmeter(List<MrpFlowmeter> list);

sql 复制代码

//错误
Integer insertBatchMrpFlowmeter(@param("list")List<MrpFlowmeter> list);
