如何将阵列添加到使用Java MongoDB的文件？(How to add an array to

我想用Java驱动程序创建MongoDB中以下文档架构

{
  "_id": {
    "$oid": "513e9820c5d0d8b93228d7e8"
  },
  "suitename": "testsuite_name",
  "testname": "testcase_name",
  "milestones": [
    {
      "milestone_id": "359",
      "testplans": [
        {
          "pland_id": "965",
          "runs": [
            6985,
            5896
          ]
        },
        {
          "plan_id": "984",
          "runs": [
            9856,
            3684
          ]
        }
      ]
    }
  ]
}

我有以下代码

BasicDBObject testObject = new BasicDBObject();
BasicDBObject milestoneObject = new BasicDBObject();

testObject.put("suitename", testsuite);
testObject.put("testname", testcase);
testObject.put("milestones", new BasicDBObject("milestone_id", "2333"));
locations.insert(testObject);

但这不是产生里程碑为一个数组。 我如何添加里程碑作为一个数组？ 我目前得到这个用我的代码

{
  "_id": {
    "$oid": "513f93dac5d0e2439d34308e"
  },
  "suitename": "test_deployment_disable_client.TestDeploymentDisableClient",
  "testname": "test_deployment_disable_client",
  "milestones": {
    "milestone_id": "2333"
  }
}

Answer 1:

更改为是这样的：

testObject.put("suitename", testsuite);
testObject.put("testname", testcase);         
List<BasicDBObject> milestones = new ArrayList<>();
milestones.add(new BasicDBObject("milestone_id", "2333"));
testObject.put("milestones", milestones);
locations.insert(testObject);

Answer 2:

你可以创建一个ArrayList这需要在DBObjects。

List<DBObject> array = new ArrayList<DBObject>();

添加创建DBOBJECT为数组内的对象，并将其添加到创建数组对象。

array.add(/* some object */);

最后，把数组中的主文档对象。

document.put("milestones", array);

Answer 3:

更好地利用：

MongoClient client = new MongoClient("localhost",27017);

MongoCollection<Document> collection =        client.getDatabase("db").getCollection("collection");

List<Document> docs=new ArrayList<>();
docs.add();

collection.insertMany(docs);

client.close();

Answer 4:

小延伸到前面的答案

    BasicDBObject testObject = new BasicDBObject();
    testObject.put("type", "milestones");
    testObject.put("usecase", "milestone_type");

    List<BasicDBObject> testplans = new ArrayList<>();
    testplans.add(new BasicDBObject("plan_id","3232"));
    testplans.add(new BasicDBObject("plan_day","sunday"));


    BasicDBObject milestoneObject = new BasicDBObject();
    milestoneObject.put("milestone_id", "3232");
    milestoneObject.put("plans", testplans);


    List<BasicDBObject> milestones = new ArrayList<>();
    milestones.add( milestoneObject);
    testObject.put("milestones", milestones);


    locations.insert(testObject);
