我正在使用弹簧数据mongdb 2.1.0。并具有以下给出的自定义存储库:
public class ProductItemRepositoryImpl implements ProductItemRepositoryCustom {
@Override
public List<String> getItemIdsGivenSkuOrCode(String itemIdType, String itemId) {
Query query = new Query();
query.addCriteria(Criteria.where(itemIdType).is(itemId));
return mongoTemplate
.findDistinct(query, FieldNames.PRODUCT_ITEM_ID, ProductItem.COLLECTION_NAME,
String.class);
}
}
自定义回购:
public interface ProductItemRepositoryCustom {
List<String> getItemIdsGivenSkuOrCode(String itemIdType, String itemId);
}
回购:
public interface ProductItemRepository
extends MongoRepository<ProductItem, Long>, ProductItemRepositoryCustom {
}
我不明白为什么它将自定义方法(getItemidSgivensKuorCode)视为属性。当我运行此功能时,请在给定的错误下面:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productItemRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property getItemIdsGivenSku found for type ProductItem!

我认为它必须用方法命名
假设您在ProductItem
中的字段是
String itemIdType;
String itemId;
方法名称为
public interface ProductItemRepositoryCustom {
List<String> findByItemIdTypeOrItemId(String itemIdType, String itemId);
}
或更安全的一面可以添加查询
@Query("{ 'itemIdType': ?0, 'itemId': ?1}")
public List<String> findByItemIdTypeOrItemId(String itemIdType, String itemId);
