I have integrated spring-data-mongodb below:

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>1.8.0.RELEASE</version>
    </dependency>

MongoConfiguration is below:

@Configuration
@EnableMongoRepositories(basePackages = { "com.eraytuncer.store.repository" })
public class MongoConfiguration extends AbstractMongoConfiguration {

    public @Bean Mongo mongo() throws UnknownHostException {
        ServerAddress serverAddress = new ServerAddress("localhost", 27017);
        MongoCredential credential = MongoCredential.createMongoCRCredential("storeUser", getDatabaseName(), "storePass".toCharArray());
        MongoClientOptions options = MongoClientOptions.builder().connectionsPerHost(4).socketKeepAlive(true).build();
        Mongo mongo = new MongoClient(serverAddress, Arrays.asList(credential), options);
        // mongo.setWriteConcern(WriteConcern.SAFE);
        return mongo;
    }

    @Bean(name = "MongoTemplate")
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongo(), getDatabaseName());
    }

    @Override
    protected String getDatabaseName() {
        return "store";
    }

}

I have the spring version 3.1.1.RELEASE. It has been configured as javaconfig.

@Configuration
public class Config(){
@Bean
public MongoDbFactory mongoDbFactory() throws UnknownHostException{
return new SimpleMongoDbFactory(new MongoClient(new MongoClientURI(protocol://username:password@servername/databasename)),"Database_name_here"); //mongodb is the protocol
}    

@Bean
public MongoTemplate mongoTemplate() throws UnknownHostException{
return new MongoTemplate(mongoDbFactory);
}
}

When you want to bootstrap this configuration in a main class, you will do that by using Spring's AnnotationConfigApplicationContext like this:

ApplicationContext context = new AnnotationConfigApplicationContext(Config.class);
MongoOperations template = context.getBean(MongoTemplate.class);

Then, you will call all the MongoTemplate's methods on MongoOperations's instance.

I have switched the spring framework version from 3.1.1.RELEASE to 4.2.2.RELEASE and these errors disappeared.
