mybatis一对多查询返回

定义实体类

InventoryVO 和InventoryDetailVO是一对多的关系。

@Data
public class InventoryVO {
    /**收发 1: 收 0：发**/
    private String inOrOut;
    /**发生日期**/
    private String occTime;
    private Long storeId;
    private Long customerId;
    private String customerName;

    /**仓库名称**/
    private String warehouseName;
    /**业务类型**/
    private String accountTypeName;
    /**业务类型**/
    private int accountType;
    /** wms单号**/
    private String wmsBillNo;
    /**货主单号**/
    private String cusBillNo;

    private List listDetails;
}

@Data
public class InventoryDetailVO {
    /** 行号**/
    private Integer lineNo;
    /** 货物编码**/
    private String itemSkuCode;
    /** 货物名称**/
    private String itemName;
    /** 包装数量**/
    private Integer packageCount;
    /** 单位名称**/
    private String unitName;
    private Long skuId;
    private String categoryName;
}

Mapper.xml文件

定义一个resullMap，返回类型是type：InventoryVO

          GROUP BY customer_id, store_id,account_id, account_type,  type) temp
          INNER JOIN warehouse_inventory_log wlog

                and temp.type = #{type}
            
        

    

Mapper.java文件

List statisticsDetails(WarehouseInventoryLogDTO warehouseInventoryLogDTO);

@Data
public class WarehouseInventoryLogDTO  extends Pager {
    private Long customerId;
