MongoDB操作类封装实例代码

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：

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;
 

public class Mongobase extends SourceCode {
 
 
 public static List getServers(ServerAddress... addresses) {
  return Arrays.asList(addresses);
 }
 
 
 public static ServerAddress getServerAdress(String host, int port) {
  return new ServerAddress(host, port);
 }
 
 
 public static List getCredentials(MongoCredential... credentials) {
  return Arrays.asList(credentials);
 }
 
 
 public static MongoCredential getMongoCredential(String userName, String database, String password) {
  return MongoCredential.createCredential(userName, database, password.toCharArray());
 }
 
 
 public static MongoClient getMongoClient(List addresses, List credentials) {
  return new MongoClient(addresses, credentials);
 }
 
 
 public static MongoDatabase getMongoDatabase(MongoClient mongoClient, String databaseName) {
  return mongoClient.getDatabase(databaseName);
 }
 
 
 public static MongoCollection getMongoCollection(MongoDatabase mongoDatabase, String collectionName) {
  return mongoDatabase.getCollection(collectionName);
 }
 
 
 public static void MongoOver(MongoClient mongoClient) {
  mongoClient.close();
 }
 
 
 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;
 }
 
 
 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));
 }
 
 
 public static MongoCollection getCollection(MongoObject mongoObject, String collectionName) {
  return getMongoClient(mongoObject).getDatabase(mongoObject.database).getCollection(collectionName);
 }
 
 
 public static MongoCollection getCollectionOnline(MongoObject mongoObject, String collectionName) {
  return getMongoClientOnline(mongoObject).getDatabase(mongoObject.database).getCollection(collectionName);
 }
 
}

mongoobject的代码如下：

package com.fun.mongodb;
 
 
import com.mongodb.MongoClient;
import com.mongodb.client.MongoCollection;
import org.bson.document;
 

public class MongoObject extends Mongobase {
 
  String host;
 
  int port;
 
  String user;
 
  String password;
 
  String database;
 
  MongoClient mongoClient;
 
  
  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);
  }
 
  
  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);
  }
 
  
  public MongoCollection getMongoCollection(String collectionName) {
    MongoClient mongoClientOnline = getMongoClientOnline(this);
    return mongoClientOnline.getDatabase(database).getCollection(collectionName);
  }
 
 
  
  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：

 public static void main(String[] args) {
    MongoObject ready = new MongoObject("*****", 5117, "fission_record", "fission_record", "fission_record");
    MongoCollection 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}}
