Java 具有多个参数的Spring数据jpa连接查询

您好，我正在尝试使用SpringJPA从MySql数据库中提取一条记录

实体1

            ", ltuQuantity='" + ltuQuantity + "'" +
            '}';
    }
}

实际上，SQL查询是有效的

select * from sku_warehouse sw 
join warehouse w  on (sw.warehouse_id = w.id)
where  w.warehouse_id='024'
 and sw.sku_master_id='1072'

Jpa查询中有什么错误？我甚至尝试传递SkuMaster对象而不是Long，但随后我得到了MySql查询异常

在我更改了我的Jpa查询和方法后，它可以正常工作，如下所示

@Query(value="SELECT * FROM sku_warehouse sw JOIN warehouse w ON (sw.warehouse_id = w.Id) WHERE w.warehouse_id=?1 AND sw.sku_master_id=?2", nativeQuery = true)
SkuWarehouse findOneWithEagerRelationships(String warehouseId, Long skuMasterId);    

---

有点像id字段是私有的，没有getter。id是实体类中定义为

@id@GeneratedValue（strategy=GenerationType.IDENTITY）private Long id的字段

我的jpa查询是否正确？堆栈跟踪显示查询已被解析，并且它正在尝试从类SkuMaster获取a字段名

id

值（作为一个长值）

private java.lang.Long.com.company.wmapi.domain.SkuMaster.id

在SkuMaster中是否有

public Long getId（）

方法？是的，我有用于id的公共getter和setter。

@Query(value="SELECT * FROM sku_warehouse sw JOIN warehouse w ON (sw.warehouse_id = w.Id) WHERE w.warehouse_id=?1 AND sw.sku_master_id=?2", nativeQuery = true)
SkuWarehouse findOneWithEagerRelationships(String warehouseId, Long skuMasterId);
