Query mongodb using Predicate and sub-document $type

Question

What I am looking for is how do you translate a query using java spring mongodb based on type of the sub-document into a Predicate.

A normal query would look something like:

Query query = new Query(Criteria.where("data").type(3)).with(pageRequest);

How do I translate this into a predicate query? Something like:

QEmployee employee = new QEmployee("employee");
return employeeRepository.findAll(employee.data.type.is(3), pageRequest);

But I am not sure how to translate it. Any help would be appreciated!

Does the current version of spring-mongo support it?

A part of my pom.xml

<properties>
    <spring.version>3.2.4.RELEASE</spring.version>
    <sd.jpa.version>1.3.4.RELEASE</sd.jpa.version>
    <sd.mongodb.version>1.2.3.RELEASE</sd.mongodb.version>
    <powermock.version>1.5</powermock.version>
</properties>

This is not yet supported in Querydsl. Feel free to create a ticket for it on GitHub.
