如何使用Java向MongoDB文档添加数组？

我想使用java驱动程序在mongoDB中创建以下文档模式

{
  "_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);

但这并不是以数组的形式生成里程碑。如何将里程碑添加为阵列？我现在用我的代码得到这个

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

---

换成这样：

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);

testObject.put（“suitename”，testsuite）；
put（“testname”，testcase）；
列表里程碑=新的ArrayList（）；
里程碑。添加（新的基本目标（“里程碑id”，“2333”）；
testObject.put（“里程碑”，里程碑）；
插入（testObject）；

您可以创建一个接受DBObjects的ArrayList

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

最后，将数组放入主文档对象中

document.put("milestones", array);

更好地使用：

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();

MongoClient客户端=新的MongoClient（“localhost”，27017）；
MongoCollection collection=client.getDatabase（“db”）.getCollection（“collection”）；
列表文档=新建ArrayList（）；
docs.add（）；
collection.insertMany（文档）；
client.close（）；

对前面的答案几乎没有扩展

    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);

BasicDBObject testObject=new BasicDBObject（）；
put（“类型”、“里程碑”）；
put（“用例”、“里程碑类型”）；
List testplans=new ArrayList（）；
添加（新的基本对象（“计划id”、“3232”）；
添加（新的基本对象（“计划日”、“星期日”）；
BasicDBObject milestoneObject=新的BasicDBObject（）；
milestoneObject.put（“里程碑id”，“3232”）；
milestoneObject.put（“计划”，测试计划）；
列表里程碑=新的ArrayList（）；
里程碑。添加（milestoneObject）；
testObject.put（“里程碑”，里程碑）；
插入（testObject）；

    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);
