Spring Data Jpa Query dsl with fetch join

Question

Is it possible to specify Join Fetch when using QueryDsl and Spring Data Repository?

Here is the spring documentation explaining what to do: docs.spring.io/spring-data/jpa/docs/current/reference/html/… — Ted Gulesserian

Yes, thanks, but I wanted to find the way how to do it without annotations. — Max

No, there's no keyword in Spring Data JPA to trigger a fetch. But you can write a Custom Repository and implement a query using Querydsl there.

It's possible to use Query annotation, and specify fetch join there. But when I implement QueryDslPredicateExecutor to my repository, I can't mix it with Query annotation.

Yes, that's right. The QueryDslPredicateExecutor can be used to perform queries only using Querydsl Predicates (where you can't use fetch()). For instance: Predicate isOld = person.age.gt(65); repository.findAll(isOld);
