Change default sort order for Spring Data findAll() method

Question

I'm using Spring Data JPA and I wonder if it is possible to change the default sort order for a entity being used by the Spring Data findAll() method?

Answer 1

You can achieve this as follows:

dao.findAll(new Sort(Sort.Direction.DESC, "colName"));
// or
dao.findAll(Sort.by("colName").descending());

Another way to achieve the same. Use the below method name:

findByOrderByIdAsc()

Answer 2

You should be able to do this by either:

in spring-data 1.5+, overriding the findAll() method in your Interface, adding the @Query annotation and creating a named Query in your Entity class like, for example, below:

Entity

@Entity
@NamedQuery(name = "User.findAll", query="select u from User u order by u.address.town")
public class User{

}

Repository

public interface UserRepository extends ... <User, Long> {

    @Override
    @Query
    public Iterable<User> findAll();
}

or,

by creating a custom repository implementation:

http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.custom-implementations

Answer 3

Use a PagingAndSortingRepository instead. With that in place you can add a queryparameter ?sort=,

Repository:

public interface UserRepository extends PagingAndSortingRepository<User, Long> {
  //no custom code needed
}
