18、MongoDB实战：Java访问MongoDB-操作集合

//创建集合
public static void createCollection(String dbName,String collName){
   
     
	MongoDatabase database = getDatabase(dbName);
	database.createCollection(collName);
}

//获取 MongoDB 中的集合
public static MongoCollection getCollection(String dbName, String collName){
   
     
	MongoDatabase database = getDatabase(dbName);
	return database.getCollection(collName);
}

//删除集合
public static void dropCollection(MongoCollection coll){
   
     
	coll.drop();
}
