I am unclear on if this question is a JPA question or a Spring/Hibernate question. If it is the later, you might try asking elsewhere, as this is a TopLink/JPA forum - TopLink is a JPA provider that includes EclipseLink. If it is JPA, you might make your question more clear, as JPA does not allow defining named queries in a text file and defining a query will not return entities from the database. JPA does allow defining queries in orm.xml or though annations on the entities themselves, and in JPA 2.1, you can add named queries in code. And entities are only returned when the query is executed, so you might want to explain a bit more what you are trying to avoid loading.
