前言
最近接到一个需求,要做MongoDB打点数据的统计,在学习过MongoDB的操作之后,封装了一个MongoDB的操作类,分为两部分,基本思想是参照了自己写过的mysql的操作类。一个是基本的操作类,包括所有基本操作的静态方法,还有一个是mongoobject,就是具体操作的实现类。
以后再写如何用spring boot写一个简单的统计服务。
MongoDB操作类封装

具体效果非常不错,测试代码如下:

public static void main(String[] args) { MongoObject ready = new MongoObject( "*****" , 5117 , "fission_record" , "fission_record" , "fission_record" ); MongoCollection<Document> app = ready.getMongoCollection( "app_logs_20181109" ); Document first = app.find().first(); output(first); ready.over(); } |
打印内容如下:
