mongoDB连接数据库

public class mongo {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		MongoClient mo = new MongoClient("127.0.0.1",27017);
		DB db = mo.getDB("wtdd");
		DBCollection col = db.getCollection("wtdd");
		DBObject o = new BasicDBObject("name","jim");
		DBCursor cur = col.find();
		for(DBObject obc:cur) {
			System.out.println(obc);
		}
	}
//db.createCollection("wt", new DBObject());
}
连接数据库输出集合数据

		DB db = mo.getDB("wtdd");
		DBCollection col = db.getCollection("wtd");
		DBObject o = new BasicDBObject("name","jim");
		DBCursor lis = col.find(o);
		for(DBObject obj:lis) {
			System.out.println(obj);
		}
