I want to store trace info like below:
{
"timestamp": 1394343677415,
"info": {
"method": "GET",
"path": "/trace",
"headers": {
"request": {
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Connection": "keep-alive",
"Accept-Encoding": "gzip, deflate",
"User-Agent": "Mozilla/5.0 Gecko/Firefox",
"Accept-Language": "en-US,en;q=0.5",
"Cookie": "_ga=GA1.1.827067509.1390890128; ..."
"Authorization": "Basic ...",
"Host": "localhost:8080"
},
"response": {
"Strict-Transport-Security": "max-age=31536000 ; includeSubDomains",
"X-Application-Context": "application:8080",
"Content-Type": "application/json;charset=UTF-8",
"status": "200"
}
}
}
My #Document entity is extending HashMap.
Now I have to write custom query for pagination.
In Mongo client shell I would write it:
db.traceInfo.find({"headers.response.status": "404"}).limit(n);
and it works, but I don't know how to write this query as #Query in Spring MongoRepository? How can I do that?

This is totally easy, but keyword limit is not supported by spring-data-mongodb, check out the reference here: https://docs.spring.io/spring-data/mongodb/docs/current/reference/html/#repository-query-keywords
Possible solution:
#Query({"headers.response.status": "?1"})
List<T> findByGivenStatus(int status);
