在Spring数据MongoDB中转换MongoDb查询

Question

I have a document with an array. I want to delete the document if array exists and size is of 0.

I came up with this mongodb query(something similar)

document.remove({ comments: { $exists: true, $size: 0 } })

please help me in converting this mongodb query to spring-data-mongodb or suggest me if there is any better solution for this.

假设您有一个Document类。

mongoTemplate.remove(new Query(Criteria.where("comments").exists(true).size(0)), Document.class);
