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

    F         


        

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:

    org.springframework.data
    spring-data-mongodb
    1.6.2.RELEASE



    org.mongodb
    mongo-java-driver
    3.0.0

having as parent

    org.springframework.boot
    spring-boot-starter-parent
    1.2.2.RELEASE

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);
