java

　　1. [代码]方法1

BasicDBObject document = new BasicDBObject();
document.put("database", "mkyongDB");
document.put("table", "hosting");
BasicDBObject documentDetail = new BasicDBObject();
documentDetail.put("records", "99");
documentDetail.put("index", "vps_index1");
documentDetail.put("active", "true");
document.put("detail", documentDetail);
collection.insert(document);

　　2. [代码]方法2

01 BasicDBObjectBuilder documentBuilder = BasicDBObjectBuilder.start()
02 .add("database", "mkyongDB")
03 .add("table", "hosting");
04
05 BasicDBObjectBuilder documentBuilderDetail = BasicDBObjectBuilder.start()
06 .add("records", "99")
07 .add("index", "vps_index1")
08 .add("active", "true");
09
10 documentBuilder.add("detail", documentBuilderDetail.get());
11
12 collection.insert(documentBuilder.get());

　　3. [代码]方法3（使用Map）

01 Map<String, Object> documentMap = new HashMap<String, Object>();
02 documentMap.put("database", "mkyongDB");
03 documentMap.put("table", "hosting");
04
05 Map<String, Object> documentMapDetail = new HashMap<String, Object>();
06 documentMapDetail.put("records", "99");
07 documentMapDetail.put("index", "vps_index1");
08 documentMapDetail.put("active", "true");
09
10 documentMap.put("detail", documentMapDetail);
11
12 collection.insert(new BasicDBObject(documentMap));

　　4. [代码]方法4（使用JSON）

1 String json = "{'database' : 'mkyongDB','table' : 'hosting'," +
2 "'detail' : {'records' : 99, 'index' : 'vps_index1', 'active' : 'true'}}}";
3
4 DBObject dbObject = (DBObject)JSON.parse(json);
5
6 collection.insert(dbObject);
