Spring Data + @Query（JPQL）+ join fetch + QueryDSL Predicate

Question

我在Repository界面中有查询方法：

public interface StudentRepository extends JpaRepository<Student, Long>, QueryDslPredicateExecutor<Student> {

    @Query("select s from Student s join fetch s.subjects join fetch s.teachers where s.firstName = ?1 and s.secondName = ?2")
    List<Student> findStudents(String firstName, String secondName)

}

工作正常！

但是我如何使用QueryDSL Predicate而不是参数？

@Query("select s from Student s join fetch s.subjects join fetch s.teachers where s.firstName = ?1 and s.secondName = ?2")
List<Student> findStudents(Predicate predicate)

非常感谢你的想法！
