Question

我的mongodb收藏中有新闻。

 {
        "_id" : ObjectId("593a97cdb17cc6535522d16a"),
        "title" : "Title",
        "text" : "Test",
        "data" : "9.06.2017, 14:39:33",
        "author" : "Admin",
        "categoryList" : [ 
            {
                "_id" : null,
                "text" : "category1"
            }, 
            {
                "_id" : null,
                "text" : "category2"
            }, 
            {
                "_id" : null,
                "text" : "category3"
            }
        ]
    }

每条新闻记录都有类别列表。我很想找到category1 categoryList newsRepository.findByCategoryList("category1");的所有新闻 variable "number_of_queues" { default = 3 } resource "aws_sqs_queue" "queue_name" { count = "${var.number_of_queues}" name = "queue_name_${count.index}" // Other properties omitted } data "aws_iam_policy_document" "my_policy" { count = "${var.number_of_queues}" statement { resources = [ "${aws_sqs_queue.queue_name[count.index].arn}", ] // Other properties omitted } } resource "aws_sqs_queue_policy" "queue_name_policy" { count = "${var.number_of_queues}" queue_url = "${aws_sqs_queue.queue_name[count.index].id}" policy = "${data.aws_iam_policy_document.my_policy[count.index].json}" }但没有工作。

怎么做？

使用您当前的存储库方法，生成的查询为

{ "categoryList" : "category1"}

您需要的是

{ "categoryList.text" : "category1"}

您可以通过两种方式创建查询。

使用存储库

findByCategoryListText(String category)

使用查询方法

@Query("{'categoryList.text': ?0}")
findByCategoryList(String category)

Spring Boot MongoDB按列表中的值查找记录
