Elasticsearch spring data - dynamic indexName in document annotation

Question

Is it possible avoid the indexName in document annotation? Because I have dynamic indexName so I cannot define it previously

Leaving aside Spring and its template, what actually do you want to achieve at Elasticsearch side? What does update any of those dynamically created indices with info to Elasticsearch mean? — Andrei Stefan

I use the ElasticsearchTemplate to create indices dynamically. I have a model which contains the Document annotation and I want to use it to update info using different indices, so I need to modify the indexName dynamically of the model to that purpose. — Carlos Vázquez Losada

According to this issue and the related PR, you can use a SpEL expression in the indexName attribute of the @Document annotation:

@Document(indexName = "#{@somePrefix}-index", type = "sometype")

where you also have a bean like the one below defined in your context

<bean id="somePrefix" class="java.lang.String">
    <constructor-arg value="${env}-myapp"/>
</bean>

So in your case, you could have a bean which contains a mutable index name that is then used to create/search the new indices.

So how can I modify the bean value from a Java method?

May the bright mind who downvoted care to explain why so all the community benefits from his wisdom ;-)

@CarlosVázquezLosada You probably should show some code so we better see what you're willing to achieve

Yo @Val I have created a new question, because this one is not mine so I couldn't paste my own code.
