mongodb-手写mongoclient加入到springmvc中

由于一个项目使用的是springmvc3.x版本, mongodb使用的为3.x版本, 所以springmvc继承的mongodb-data并不可用, 只能自己手写一个mongoclient并加入到spring-context中去

参数使用springmvc通过配置文件向bean中注入的方式

package com.iwhere.rongyun.config;

import java.util.ArrayList;

import java.util.List;

import org.apache.commons.lang3.StringUtils;

import org.bson.Document;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Configuration;

import com.iwhere.rongyun.utils.DateUtils;

import com.mongodb.MongoClient;

import com.mongodb.MongoClientOptions;

import com.mongodb.MongoCredential;

import com.mongodb.ServerAddress;

import com.mongodb.client.MongoCollection;

import com.mongodb.client.MongoDatabase;

@Configuration

public class MongoConfig {

    private static Logger LOGGER = LoggerFactory.getLogger(MongoConfig.class);

    @Value("${mongodb.hostports}")

    private String hostports;

    @Value("${mongodb.maxConnect}")

    private String maxConnect;

    @Value("${mongodb.maxWaitThread}")

    private String maxWaitThread;

    @Value("${mongodb.maxTimeOut}")

    private String maxTimeOut;

    @Value("${mongodb.maxWaitTime}")

    private String maxWaitTime;

    @Value("${mongodb.username}")

    private String username;

    @Value("${mongodb.password}")

    private String password;

    @Value("${mongodb.database}")

    private String database;

    @Value("${mongodb.collection}")

    private String collection;

    @Bean

    public MongoClient mongoClient() {

        MongoClient mongoClient = null;

        MongoClientOptions.Builder build = new MongoClientOptions.Builder();

        build.connectionsPerHost(Integer.valueOf(maxConnect));

        build.threadsAllowedToBlockForConnectionMultiplier(Integer.valueOf(maxWaitThread));

        build.connectTimeout(Integer.valueOf(maxTimeOut) * );

        build.maxWaitTime(Integer.valueOf(maxWaitTime) * );

        MongoClientOptions options = build.build();

        try {

            List<ServerAddress> addrs = new ArrayList<ServerAddress>();

            for (String hostport : hostports.split(", *")) {

                if (StringUtils.isBlank(hostport)) {

                    continue;

                }

                hostport = hostport.trim();

                ServerAddress serverAddress = new ServerAddress(hostport.split(":")[],Integer.valueOf(hostport.split(":")[]));

                addrs.add(serverAddress);

            }

            MongoCredential credential = MongoCredential.createScramSha1Credential(username, database, password.toCharArray());

            List<MongoCredential> credentials = new ArrayList<MongoCredential>();

            credentials.add(credential);

            mongoClient = new MongoClient(addrs,credentials, options);

            LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + "admin" + " mongodb客户端创建成功 " + "admin");

        } catch (Exception e) {

            LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + "admin" + " mongodb客户端创建失败 " + "admin");

            e.printStackTrace();

        }

        return mongoClient;

    }

    @Bean

    public MongoDatabase mongoDatabase(MongoClient mongoClient) {

         MongoDatabase mongoDatabase = mongoClient.getDatabase(database);

         return mongoDatabase;

    }

    @Bean

    public MongoCollection<Document> mongoCollection(MongoDatabase mongoDatabase) {

        MongoCollection<Document> mongoCollection = mongoDatabase.getCollection(collection);

//        mongoDatabase.createCollection(collection);

        return mongoCollection;

    }

}

然后是service层

package com.iwhere.rongyun.mongodb.impl;

import static com.mongodb.client.model.Filters.eq;

import org.bson.Document;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.alibaba.fastjson.JSON;

import com.iwhere.rongyun.mongodb.MongoService;

import com.iwhere.rongyun.utils.DateUtils;

import com.mongodb.client.MongoCollection;

import com.mongodb.client.model.FindOneAndUpdateOptions;

@Service

@Transactional

public class MongoServiceImpl implements MongoService {

    private static Logger LOGGER = LoggerFactory.getLogger(MongoServiceImpl.class);

    @Autowired

    private MongoCollection<Document> mongoCollection;

    @Override

    public Boolean isUserLogin(String userId) {

        Document first = mongoCollection.find(eq("userId", userId)).first();

        if (first == null) {

            LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + userId + " 用户不存在 " + userId);

            return false;

        }

        String flag = first.getString("status");

        LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + userId + " 用户存在 " + first);

        return "".equals(flag) ? true : false;

    }

    @Override

    public Boolean upsert(String userId, String status, String os, String time) {

        Document update = new Document();

        update.append("status", status);

        update.append("os", os);

        update.append("time", time);

        try {

            @SuppressWarnings("unused")

            Document result = mongoCollection.findOneAndUpdate(eq("userId", userId), new Document("$set", update),

                    new FindOneAndUpdateOptions().upsert(true));

            update.append("userId", userId);

            LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + userId + " mongodb存储成功 "

                    + JSON.toJSONString(update));

            return true;

        } catch (Exception e) {

            update.append("userId", userId);

            LOGGER.info("20-02 " + DateUtils.getDateTime() + " 10-03 " + userId + " mongodb存储失败 "

                    + JSON.toJSONString(update) + "-" + e.getMessage());

            e.printStackTrace();

            return false;

        }

    }

}
