问题描述
在 Spring CrudRepository 中,我们是否支持字段的IN 子句"?即类似于以下内容?
In Spring CrudRepository, do we have support for "IN clause" for a field? ie something similar to the following?
findByInventoryIds(List<Long> inventoryIdList)
如果没有这样的支持,可以考虑哪些优雅的选择?为每个 id 触发查询可能不是最优的.
If such support is not available, what elegant options can be considered? Firing queries for each id may not be optimal.
推荐答案
findByInventoryIdIn(List
应该可以解决问题.
HTTP 请求参数格式如下:
The HTTP request parameter format would be like so:
Yes ?id=1,2,3
No ?id=1&id=2&id=3
JPA 存储库关键字的完整列表可以在 当前文档列表.它表明 IsIn
是等价的 - 如果您更喜欢动词以提高可读性 - 而且 JPA 还支持 NotIn
和 IsNotIn
.
The complete list of JPA repository keywords can be found in the current documentation listing. It shows that IsIn
is equivalent – if you prefer the verb for readability – and that JPA also supports NotIn
and IsNotIn
.
