Spring data elasticsearch with username and password

Question

I am using spring data for the elasticsearch and using transport client with the below configuration for elasticsearchtemplate. I am wondering how we can provide the shield user name and password to the elasticsearchtemplate. Can we do that?

<elasticsearch:repositories base-package="edu.mayo.registry.fhir.rest.elasticsearch.repository" />

<elasticsearch:transport-client id="client" client-transport-sniff="true" client-transport-ping-timeout="30s" client-transport-nodes-sampler-interval="30s" 
    cluster-nodes="hostname:9300" />

<!-- <elasticsearch:node-client id="client" local="true"/> -->

<bean name="elasticsearchTemplate"
    class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate">
    <constructor-arg name="client" ref="client" />
</bean>
