是的，你可以在Spring Data中使用查询方法进行排序。

例如:使用id字段的值按升序或降序排列。

代码:

  public interface StudentDAO extends JpaRepository<StudentEntity, Integer> {
    public findAllByOrderByIdAsc();   
}

可选择的解决方案:

    @Repository
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(orderByIdAsc());
    }
private Sort orderByIdAsc() {
    return new Sort(Sort.Direction.ASC, "id")
                .and(new Sort(Sort.Direction.ASC, "name"));
}
}

Spring Data Sorting:排序

结合以上所有答案，你可以用BaseEntity编写可重用的代码:

@Data
@NoArgsConstructor
@MappedSuperclass
public abstract class BaseEntity {

  @Transient
  public static final Sort SORT_BY_CREATED_AT_DESC = 
                        Sort.by(Sort.Direction.DESC, "createdAt");

  @Id
  private Long id;
  private LocalDateTime createdAt;
  private LocalDateTime updatedAt;

  @PrePersist
  void prePersist() {
    this.createdAt = LocalDateTime.now();
  }

  @PreUpdate
  void preUpdate() {
    this.updatedAt = LocalDateTime.now();
  }
}

DAO对象重载findAll方法——基本上，仍然使用findAll()

public interface StudentDAO extends CrudRepository<StudentEntity, Long> {

  Iterable<StudentEntity> findAll(Sort sort);

}

StudentEntity扩展了包含可重复字段的BaseEntity(也许你也想按ID排序)

@Getter
@Setter
@FieldDefaults(level = AccessLevel.PRIVATE)
@Entity
class StudentEntity extends BaseEntity {

  String firstName;
  String surname;

}

最后，SORT_BY_CREATED_AT_DESC的服务和用法，它可能不仅会在StudentService中使用。

@Service
class StudentService {

  @Autowired
  StudentDAO studentDao;

  Iterable<StudentEntity> findStudents() {
    return this.studentDao.findAll(SORT_BY_CREATED_AT_DESC);
  }
}

public interface StudentDAO extends JpaRepository<StudentEntity, Integer> {
    public List<StudentEntity> findAllByOrderByIdAsc();
}

上面的代码应该可以工作。我用的是类似的东西:

public List<Pilot> findTop10ByOrderByLevelDesc();

它返回最高级别的10行。

重要的是: 因为我被告知很容易忽略这个答案的关键点，这里有一点澄清:

findAllByOrderByIdAsc(); // don't miss "by"
       ^

AFAIK，我认为这对于直接的方法命名查询是不可能的。不过，您可以使用Sort类来使用内置的排序机制。存储库有一个findAll(Sort)方法，您可以将Sort的实例传递给该方法。例如:

import org.springframework.data.domain.Sort;

@Repository
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(sortByIdAsc());
    }

    private Sort sortByIdAsc() {
        return new Sort(Sort.Direction.ASC, "id");
    }
} 

是的，你可以在Spring Data中使用查询方法进行排序。

  public interface StudentDAO extends JpaRepository<StudentEntity, Integer> {
    public findAllByOrderByIdAsc();   
}

public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(orderByIdAsc());
    }
private Sort orderByIdAsc() {
    return new Sort(Sort.Direction.ASC, "id")
                .and(new Sort(Sort.Direction.ASC, "name"));
}
}

Spring Data Sorting:排序

在这个示例中，我试图向您展示一个完整的示例，以个性化您的orderderby排序

 import java.util.List;
 import org.springframework.data.domain.Page;
 import org.springframework.data.domain.Sort;
 import org.springframework.data.jpa.repository.*;
 import org.springframework.data.repository.query.Param;
 import org.springframework.stereotype.Repository;
 import org.springframework.data.domain.Sort;
 /**
 * Spring Data  repository for the User entity.
 */
 @SuppressWarnings("unused")
 @Repository
 public interface UserRepository extends JpaRepository<User, Long> {
 List <User> findAllWithCustomOrderBy(Sort sort);
 }

你可以用这个例子: 动态构建Sort实例的对象的方法:

import org.springframework.data.domain.Sort;
public class SampleOrderBySpring{
 Sort dynamicOrderBySort = createSort();
     public static void main( String[] args )
     {
       System.out.println("default sort \"firstName\",\"name\",\"age\",\"size\" ");
       Sort defaultSort = createStaticSort();
       System.out.println(userRepository.findAllWithCustomOrderBy(defaultSort ));


       String[] orderBySortedArray = {"name", "firstName"};
       System.out.println("default sort ,\"name\",\"firstName\" ");
       Sort dynamicSort = createDynamicSort(orderBySortedArray );
       System.out.println(userRepository.findAllWithCustomOrderBy(dynamicSort ));
      }
      public Sort createDynamicSort(String[] arrayOrdre) {
        return  Sort.by(arrayOrdre);
        }

   public Sort createStaticSort() {
        String[] arrayOrdre  ={"firstName","name","age","size");
        return  Sort.by(arrayOrdre);
        }
}
