我尝试使用拉操作从集合中的数组中删除元素，但它不起作用

Mongo shell 代码

db.spyne_share.update({"projectId":"3585"},{$pull:{"photoList":{$elemMatch:{photoId:"shrU17266w"}}}})

Java 代码

            Update update = new Update()
                    .pull("photoList", new BasicDBObject("photoList.photoId",photoId));
            mongoTemplate.updateFirst(new Query(Criteria.where("projectId").is(projectId)), update, "spyne_share");
        } catch (Exception e) {
            e.printStackTrace();
        }

我的这两个代码都不起作用。请帮帮我。谢谢

通过将 photoList.photoId 更改为 photoId 获得完美响应

            Query query = Query.query(Criteria.where("projectId").is(projectId));
            Update update = new Update().pull("photoList", new BasicDBObject("photoId", photoId));
            mongoTemplate.updateMulti(query, update, SpyneShareProject.class);
        } catch (Exception e) {
            e.printStackTrace();
        }```
