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
mongobase代码如下：

mongoobject的代码如下：

package com.fun.mongodb;
import com.mongodb.MongoClient; import com.mongodb.client.MongoCollection; import org.bson.Document;
/** * mongo数据库配置对象，针对单个数据服务，单个身份验证 */ public class MongoObject extends MongoBase {
String host;
int port;
String user;
String password;
String database;
MongoClient mongoClient;
/** * 创建数据连接 * * @param host * @param port * @param user * @param password * @param database */ public MongoObject(String host, int port, String user, String password, String database) { this .host = host; this .port = port; this .user = user; this .password = password; this .database = database; this .mongoClient = getMongoClient( this ); }
/** * 创建数据库连接 * * @param port * @param host * @param user * @param password * @param database */ public MongoObject( int port, String host, String user, String password, String database) { this .host = host; this .port = port; this .user = user; this .password = password; this .database = database; this .mongoClient = getMongoClientOnline( this ); }
/** * 获取colletion对象 * * @param collectionName * @return */ public MongoCollection<Document> getMongoCollection(String collectionName) { MongoClient mongoClientOnline = getMongoClientOnline( this ); return mongoClientOnline.getDatabase(database).getCollection(collectionName); }
/** * 关闭连接 */ public void over() { MongoOver( this .mongoClient); } } @Override public MongoObject clone() { return new MongoObject( this .host, this .port, this .user, this .password, this .database); }
public MongoObject clone2() { return new MongoObject( this .port, this .host, this .user, this .password, this .database); } |
具体效果非常不错，测试代码如下：
|
1 2 3 4 5 6 7 |
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：
Document{{_id=5be4ce052ce01b21b6c26a64, _class=com.fission.next.record.bean.AppRecordBean, user_id=5482, action_type={"gameId":2,"userId":"5482"}, action_extern=DataSta_Game_Starts, client_version=15, client_ip=114.5.146.239, client_imei=UNKNOWN, client_dev=xiaomi-Redmi 5 Plus, client_type=200, server_time=1541721601655, os_name=200, os_version=15, client_time=1541721577025}}
