前言
最近接到一個(gè)需求，要做MongoDB打點(diǎn)數(shù)據(jù)的統(tǒng)計(jì)，在學(xué)習(xí)過MongoDB的操作之后，封裝了一個(gè)MongoDB的操作類，分為兩部分，基本思想是參照了自己寫過的mysql的操作類。一個(gè)是基本的操作類，包括所有基本操作的靜態(tài)方法，還有一個(gè)是mongoobject，就是具體操作的實(shí)現(xiàn)類。
以后再寫如何用spring boot寫一個(gè)簡(jiǎn)單的統(tǒng)計(jì)服務(wù)。
MongoDB操作類封裝
mongobase代碼如下：
package com.fun.mongodb;
import com.fun.frame.SourceCode;
import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.MongoCredential;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
import java.util.Arrays;
import java.util.List;
/**
* mongo操作類的基礎(chǔ)類
*/
public class MongoBase extends SourceCode {
/**
* 獲取服務(wù)地址list
*
* @param addresses
* @return
*/
public static ListServerAddress> getServers(ServerAddress... addresses) {
return Arrays.asList(addresses);
}
/**
* 獲取服務(wù)地址
*
* @param host
* @param port
* @return
*/
public static ServerAddress getServerAdress(String host, int port) {
return new ServerAddress(host, port);
}
/**
* 獲取認(rèn)證list
*
* @param credentials
* @return
*/
public static ListMongoCredential> getCredentials(MongoCredential... credentials) {
return Arrays.asList(credentials);
}
/**
* 獲取驗(yàn)證
*
* @param userName
* @param database
* @param password
* @return
*/
public static MongoCredential getMongoCredential(String userName, String database, String password) {
return MongoCredential.createCredential(userName, database, password.toCharArray());
}
/**
* 獲取mongo客戶端
*
* @param addresses
* @param credentials
* @return
*/
public static MongoClient getMongoClient(ListServerAddress> addresses, ListMongoCredential> credentials) {
return new MongoClient(addresses, credentials);
}
/**
* 連接mongo數(shù)據(jù)庫(kù)
*
* @param mongoClient
* @param databaseName
* @return
*/
public static MongoDatabase getMongoDatabase(MongoClient mongoClient, String databaseName) {
return mongoClient.getDatabase(databaseName);
}
/**
* 連接mongo集
*
* @param mongoDatabase
* @param collectionName
* @return
*/
public static MongoCollectionDocument> getMongoCollection(MongoDatabase mongoDatabase, String collectionName) {
return mongoDatabase.getCollection(collectionName);
}
/**
* 關(guān)閉數(shù)據(jù)庫(kù)連接
*
* @param mongoClient
*/
public static void MongoOver(MongoClient mongoClient) {
mongoClient.close();
}
/**
* 獲取mongo客戶端對(duì)象，通過servers和credentials對(duì)象創(chuàng)建
*
* @param mongoObject
* @return
*/
public static MongoClient getMongoClient(MongoObject mongoObject) {
MongoClient mongoClient = new MongoClient(getServers(getServerAdress(mongoObject.host, mongoObject.port)), getCredentials(getMongoCredential(mongoObject.user, mongoObject.database, mongoObject.password)));
return mongoClient;
}
/**
* 獲取mongo客戶端對(duì)象,通過uri方式連接
*
* @param mongoObject
* @return
*/
public static MongoClient getMongoClientOnline(MongoObject mongoObject) {
String format = String.format("mongodb://%s:%s@%s:%d/%s", mongoObject.user, mongoObject.password, mongoObject.host, mongoObject.port, mongoObject.database);
return new MongoClient(new MongoClientURI(format));
}
/**
* 獲取collection對(duì)象
*
* @param mongoObject
* @return
*/
public static MongoCollectionDocument> getCollection(MongoObject mongoObject, String collectionName) {
return getMongoClient(mongoObject).getDatabase(mongoObject.database).getCollection(collectionName);
}
/**
* 獲取collection對(duì)象
*
* @param mongoObject
* @return
*/
public static MongoCollectionDocument> getCollectionOnline(MongoObject mongoObject, String collectionName) {
return getMongoClientOnline(mongoObject).getDatabase(mongoObject.database).getCollection(collectionName);
}
}
mongoobject的代碼如下：
package com.fun.mongodb;
import com.mongodb.MongoClient;
import com.mongodb.client.MongoCollection;
import org.bson.Document;
/**
* mongo數(shù)據(jù)庫(kù)配置對(duì)象，針對(duì)單個(gè)數(shù)據(jù)服務(wù)，單個(gè)身份驗(yàn)證
*/
public class MongoObject extends MongoBase {
String host;
int port;
String user;
String password;
String database;
MongoClient mongoClient;
/**
* 創(chuàng)建數(shù)據(jù)連接
*
* @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);
}
/**
* 創(chuàng)建數(shù)據(jù)庫(kù)連接
*
* @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);
}
/**
* 獲取colletion對(duì)象
*
* @param collectionName
* @return
*/
public MongoCollectionDocument> getMongoCollection(String collectionName) {
MongoClient mongoClientOnline = getMongoClientOnline(this);
return mongoClientOnline.getDatabase(database).getCollection(collectionName);
}
/**
* 關(guān)閉連接
*/
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);
}
具體效果非常不錯(cuò)，測(cè)試代碼如下：
public static void main(String[] args) {
MongoObject ready = new MongoObject("*****", 5117, "fission_record", "fission_record", "fission_record");
MongoCollectionDocument> app = ready.getMongoCollection("app_logs_20181109");
Document first = app.find().first();
output(first);
ready.over();
}
打印內(nèi)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}}
總結(jié)
