Convert Elastic Search Results to POJO - elasticsearch

Question

I have a project using the spring-data-elasticsearch library. I've got my system returning results, but I was wondering how to get my results in the form of my domain POJO class.
I'm not seeing too much documentation on how to accomplish this, but I don't know what the right question I should be Googling for.
Currently, my code looks like this, and in my tests, it retrieves the right results, but not as a POJO.
QueryBuilder matchQuery = QueryBuilders.queryStringQuery(searchTerm).defaultOperator(QueryStringQueryBuilder.Operator.AND);
Client client = elasticsearchTemplate.getClient();
SearchRequestBuilder request = client
.prepareSearch("mediaitem")
.setSearchType(SearchType.QUERY_THEN_FETCH)
.setQuery(matchQuery)
.setFrom(0)
.setSize(100)
.addFields("title", "description", "department");
System.out.println("SEARCH QUERY: " + request.toString());
SearchResponse response = request.execute().actionGet();
SearchHits searchHits = response.getHits();
SearchHit[] hits = searchHits.getHits();
Any help is greatly appreciated.

One option is to use jackson-databind to map JSON from the search hits to POJOs.
For example:
ObjectMapper objectMapper = new ObjectMapper();
SearchHit[] hits = searchHits.getHits();
Arrays.stream(hits).forEach(hit -> {
String source = hit.getSourceAsString();
MediaItem mediaItem = objectMapper.readValue(source, MediaItem.class);
// Use media item...
});
