MongoDB document containing sub-document to Java Class with Jongo

Question

I have the following document in a Mongo collection:

{ "_id" : ObjectId("5757fe72998660e2bc86b85f"), "projectCode" : "ABC", "projectName" : "ABC Dev", "sprintIssueCount" : { "bugs" : 17, "enhancements" : 7, "newFeatures" : 31 } }

I am then using Jongo (with Play Framework) to grab this from the database and put it into a Java class with:

return projects().findOne("{projectCode: #}", code).as(Project.class);

With the Project class containing the following fields:

@JsonProperty("_id")
public String id;

public String projectCode;
public String projectName;
public JsonObject sprintIssueCount;

However, sprintIssueCount returns empty { }. How can I grab the sub-document's contents?

Answer 1

Figured it out. Using Map instead of JsonObject:

public Map<String, Integer> sprintIssueCount;
