package cn.zno.mongodb;

import org.bson.Document;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.client.MongoCollection;

public class CustomMongoClient {

    private final Logger logger = LoggerFactory.getLogger(getClass());

    private MongoClient mongoClient;
    private MongoCollection<Document> mongoCollection;

    private String uri;
    private String dbName;
    private String collectionName;

    public void init() {
        MongoClientURI mongoClientURI = new MongoClientURI(uri);
        mongoClient = new MongoClient(mongoClientURI);
        mongoCollection = mongoClient.getDatabase(dbName).getCollection(collectionName);
        logger.info("MongoClient init");
    }

    public void destroy() {
        mongoClient.close();
        logger.info("MongoClient closed");
    }

    public MongoCollection<Document> getCollection() {
        return this.mongoCollection;
    }

    public String getUri() {
        return uri;
    }

    public void setUri(String uri) {
        this.uri = uri;
    }

    public String getDbName() {
        return dbName;
    }

    public void setDbName(String dbName) {
        this.dbName = dbName;
    }

    public String getCollectionName() {
        return collectionName;
    }

    public void setCollectionName(String collectionName) {
        this.collectionName = collectionName;
    }
}

如何使用：

    @Autowired
    private CustomMongoClient mongoClient;

    public void dd() {
        Document document = new Document();
        document.append("title", "天气日报");
        document.append("content", "晴");
        mongoClient.getCollection().insertOne(document);
    }
