Notes

TencentDB for MongoDB provides two usernames rwuser and mongouser by default to support the MONGODB-CR and SCRAM-SHA-1 authentication methods, respectively. The connecting URIs for the two authentication methods are formed differently. For more information, please see Instance Connection.

Quick Start

Native Java sample code

package mongodbdemo;

import org.bson.*;
import com.mongodb.*;
import com.mongodb.client.*;

public class MongodbDemo {

    public static void main(String[] args) {
        String mongoUri = "mongodb://mongouser:thepasswordA1@10.66.187.127:27017/admin";
        MongoClientURI connStr = new MongoClientURI(mongoUri);
        MongoClient mongoClient = new MongoClient(connStr);
        try {
            // Use the database `someonedb`
            MongoDatabase database = mongoClient.getDatabase("someonedb");
            // Get the handle of the collection/table `someonetable`
            MongoCollection<Document> collection = database.getCollection("someonetable");

            // Prepare to write data
            Document doc = new Document();
            doc.append("key", "value");
            doc.append("username", "jack");
            doc.append("age", 31);

            // Write data
            collection.insertOne(doc);
            System.out.println("insert document: " + doc);

            // Read data
            BsonDocument filter = new BsonDocument();
            filter.append("username", new BsonString("jack"));
            MongoCursor<Document> cursor = collection.find(filter).iterator();
            while (cursor.hasNext()) {
                System.out.println("find document: " + cursor.next());
            }
        } finally {
            // Close the connection
            mongoClient.close();
        }
    }
}

Output:

Configuration sample for Spring Data MongoDB

This sample demonstrates how to configure the authentication database admin, which depends on the versions of Spring and Spring Data MongoDB you use.

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>
<bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
    <constructor-arg name="mongo" ref="mongo" />
    <constructor-arg name="databaseName" value="your target database" />
    <constructor-arg name="credentials" ref="userCredentials" />
    <constructor-arg name="authenticationDatabaseName" value="admin" />
</bean>
<bean id="userCredentials" class="org.springframework.data.authentication.UserCredentials">
    <constructor-arg name="username" value="username" />
    <constructor-arg name="password" value="password" />
</bean>
