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; /** * mongo操作类的基础类 */public class MongoBase extends SourceCode { /** * 获取服务地址list * * @param addresses * @return */ public static List<ServerAddress> getServers(ServerAddress... addresses) { return Arrays.asList(addresses); } /** * 获取服务地址 * * @param host * @param port * @return */ public static ServerAddress getServerAdress(String host, int port) { return new ServerAddress(host, port); } /** * 获取认证list * * @param credentials * @return */ public static List<MongoCredential> getCredentials(MongoCredential... credentials) { return Arrays.asList(credentials); } /** * 获取验证 * * @param userName * @param database * @param password * @return */ public static MongoCredential getMongoCredential(String userName, String database, String password) { return MongoCredential.createCredential(userName, database, password.toCharArray()); } /** * 获取mongo客户端 * * @param addresses * @param credentials * @return */ public static MongoClient getMongoClient(List<ServerAddress> addresses, List<MongoCredential> credentials) { return new MongoClient(addresses, credentials); } /** * 连接mongo数据库 * * @param mongoClient * @param databaseName * @return */ public static MongoDatabase getMongoDatabase(MongoClient mongoClient, String databaseName) { return mongoClient.getDatabase(databaseName); } /** * 连接mongo集 * * @param mongoDatabase * @param collectionName * @return */ public static MongoCollection<Document> getMongoCollection(MongoDatabase mongoDatabase, String collectionName) { return mongoDatabase.getCollection(collectionName); } /** * 关闭数据库连接 * * @param mongoClient */ public static void MongoOver(MongoClient mongoClient) { mongoClient.close(); } /** * 获取mongo客户端对象，通过servers和credentials对象创建 * * @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; } /** * 获取mongo客户端对象,通过uri方式连接 * * @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)); } /** * 获取collection对象 * * @param mongoObject * @return */ public static MongoCollection<Document> getCollection(MongoObject mongoObject, String collectionName) { return getMongoClient(mongoObject).getDatabase(mongoObject.database).getCollection(collectionName); } /** * 获取collection对象 * * @param mongoObject * @return */ public static MongoCollection<Document> 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; /** * 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：

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}}
