Connecting to MongoDB 3.0 with Java Spring

Question

I am having problems in using Spring to access MongoDB with credentials. While without credentials it works like a charme, using them just fails saying

    Failed to authenticate to database [yourdatabase], username = [yourusername], password = [x******z] 

It must be because of new auth default that you can read about in http://docs.mongodb.org/manual/core/authentication/

Changed in version 3.0: SCRAM-SHA-1 is the default mechanism for MongoDB versions beginning with the 3.0 series.

Question: Anybody found out a way to use Spring with credentials ? Which version of spring-data-mongodb did you use to make the trick ?

Answer 1

After a lot of attempts and reading, I found a way to make MongoDB 3.0 work with authentication.

This was a new installation of MongoDB 3.0, no upgrade involved.

I used these maven dependencies:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.6.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.0.0</version>
</dependency>

having as parent

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.2.RELEASE</version>
</parent>

Then in my Configuration file I had

/**
 * DB connection Factory
 * 
 * @return a ready to use MongoDbFactory
 */
@Bean
public MongoDbFactory mongoDbFactory() throws Exception {

    // Set credentials      
    MongoCredential credential = MongoCredential.createCredential(mongoUser, databaseName, mongoPass.toCharArray());
    ServerAddress serverAddress = new ServerAddress(mongoHost, mongoPort);

    // Mongo Client
    MongoClient mongoClient = new MongoClient(serverAddress,Arrays.asList(credential)); 

    // Mongo DB Factory
    SimpleMongoDbFactory simpleMongoDbFactory = new SimpleMongoDbFactory(
            mongoClient, databaseName);

    return simpleMongoDbFactory;
}

/**
 * Template ready to use to operate on the database
 * 
 * @return Mongo Template ready to use
 */
@Bean
public MongoTemplate mongoTemplate() throws Exception {
    return new MongoTemplate(mongoDbFactory());
}

And finally wherever you have access to the MongoTemplate bean you'll be able to do

mongoTemplate.insert(objectToStore, collectionName);
