mongodb配置使用

      下载mongodb地址http://www.mkyong.com/mongodb/how-to-install-mongodb-on-windows/,mongodb数据库包括10个可执行exe文件,启动数据库并创建一个数据库名mongodb --dbpath "d:\mongodb" 即可。启动后可用通过http:localhost:http://localhost:28017/可以访问mongodb运行情况

       java连接mongodb,

public static void main(String[] args) {

		try {
			// connect to mongoDB, ip and port number
			Mongo mongo = new Mongo("localhost", 27017);

			// get database from MongoDB,
			// if database doesn't exists, mongoDB will create it automatically
			DB db = mongo.getDB("mongod");

			// Get collection from MongoDB, database named "yourDB"
			// if collection doesn't exists, mongoDB will create it
			// automatically
			DBCollection collection = db.getCollection("yourCollection");

			// create a document to store key and value
			BasicDBObject document = new BasicDBObject();
			document.put("id", 1001);
			document.put("msg", "hello world mongoDB in Java");

			// save it into collection named "yourCollection"
			collection.insert(document);

			// search query
			BasicDBObject searchQuery = new BasicDBObject();
			searchQuery.put("id", 1001);

			// query it
			DBCursor cursor = collection.find(searchQuery);

			// loop over the cursor and print it retrieved result
			while (cursor.hasNext()) {
				System.out.println(cursor.next());
			}

			System.out.println("Done");
			
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (MongoException e) {
			e.printStackTrace();
		}

	}

    如何让mongo作为系统服务运行，启动命令:
mongod -dbpath E:\mongodbpath -logpath E:\mongodbpath\log\log.txt -port 27017 -install
