Java操作Mongo

// 创建连接MongoClient mongoClient = new MongoClient(Arrays.asList(new ServerAddress("localhost", 27017),                                      new ServerAddress("localhost", 27018),                                      new ServerAddress("localhost", 27019)));//使用mydb数据库DB db = mongoClient.getDB( "mydb" );//获取所有CollectionSet<String> colls = db.getCollectionNames();for (String s : colls) {    System.out.println(s);}//获取特定CollectionDBCollection coll = db.getCollection("testCollection");//写入一个DocumentBasicDBObject doc = new BasicDBObject("name", "MongoDB")        .append("type", "database")        .append("count", 1)        .append("info", new BasicDBObject("x", 203).append("y", 102));coll.insert(doc);//查询一个Collection中第一个DocumentDBObject myDoc = coll.findOne();System.out.println(myDoc);//查询Collection中所有DocumentsDBCursor cursor = coll.find();try {   while(cursor.hasNext()) {       System.out.println(cursor.next());   }} finally {   cursor.close();}
