JpaRepository JOIN JPQL 查询 WITH Pageable 对象。 如何实施？

Question

I have two tables user and userprofiles .

User

mysql> SHOW columns FROM user;
+----------+--------------+------+-----+---------+----------------+
| Field    | Type         | Null | Key | Default | Extra          |
+----------+--------------+------+-----+---------+----------------+
| id       | int(11)      | NO   | PRI | NULL    | auto_increment |
| name     | varchar(45)  | YES  |     | NULL    |                |
| password | varchar(255) | NO   |     | NULL    |                |
| email    | varchar(45)  | NO   | UNI | NULL    |                |
+----------+--------------+------+-----+---------+----------------+
5 rows in set (0.01 sec)

and UserProfiles

mysql> SHOW columns FROM userprofiles;
+---------------+---------------+------+-----+-------------------------+----------------+
| Field         | Type          | Null | Key | Default                 | Extra          |
+---------------+---------------+------+-----+-------------------------+----------------+
| userprofileid | int(11)       | NO   | PRI | NULL                    | auto_increment |
| userid        | int(11)       | NO   | MUL | NULL                    |                |
| userpics      | varchar(45)   | YES  |     | /images/faces/face2.jpg |                |.
.
.
.
| datecreated   | datetime      | YES  |     | CURRENT_TIMESTAMP       |                |
+---------------+---------------+------+-----+-------------------------+----------------+
15 rows in set (0.00 sec)

And These two entities are One to One relationship.

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id")
    private int id;
...
..
    @OneToOne(mappedBy = "user", cascade = CascadeType.ALL, fetch = FetchType.LAZY, optional = false)
    private UserProfile userProfile;
..

and UserProflies entity

@Entity
@Table(name="userprofiles")
public class UserProfile {

    @OneToOne(fetch = FetchType.LAZY)
    @MapsId
    @JoinColumn(name="userid")
    private User user;

    @Id
    private int id;
...
..

As you can see, only in UserProflies table has a datecreated infomation. What I want to do is, get all User descending order by datecreated .

So, In my controller.

@GetMapping("/allUserInfo")
    public String getAllUserInfo(@PageableDefault(page = 1) Pageable pageable, Model model) { 

        int pageNum = pageable.getPageNumber(); 
        pageable = new PageRequest(pageNum, 10, new Sort(Sort.Direction.DESC, "datecreated"));

        Page<User> users = userService.findAll(pageable);
        model.addAttribute("users", users);

        return "_allUserInfo";
    }

As My DAO interface extends JpaRepository class. I tried like this..

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserDAO userDAO;
..
.
    @Override
    public Page<User> findAll(Pageable pageable) {
        return userDAO.findAll(pageable);
    }
..

@Repository
public interface UserDAO extends JpaRepository<User, Long> {

    @Query("SELECT u FROM userprofile upf JOIN upf.user u")
    Page<User> findAll(Pageable pageable);
}

but It failed.. I just want to take User Pageable Objects ordered by datecreated . so that I can display it to the view. Am I on the right track? or there are other way of doing this?

Validation failed for query for method public abstract org.springframework.data.domain.Page com.myfolder.boards.dao.UserDAO.findAll(org.springframework.data.domain.Pageable)!

Above is error msg..

EDIT+2

Silly Me.

@Query("SELECT u FROM UserProfile upf JOIN upf.user u")

this worked.

Answer 1

take a look at: https://www.baeldung.com/spring-data-jpa-pagination-sorting

You could extend the PagingAndSortingRepository interface:

public interface ProductRepository extends PagingAndSortingRepository<Product, Integer> {

    List<Product> findAllByPrice(double price, Pageable pageable);
}

then you can do:

Pageable sortedByName = 
  PageRequest.of(0, 3, Sort.by("name"));

Pageable sortedByPriceDesc = 
  PageRequest.of(0, 3, Sort.by("price").descending());

Pageable sortedByPriceDescNameAsc = 
  PageRequest.of(0, 5, Sort.by("price").descending().and(Sort.by("name")));

Answer 2

There is many problems in your question:

1 - You're querying about the whole entity "User u" in your query. Are you sure that you need all attributes? Maybe you should use query with constructor to one DTO. (Example in manish answer here) How to return a custom object from a Spring Data JPA GROUP BY query

2 - You're querying in User and sorting by a field that is not in User entity. Maybe you should use this query in UserProfile Repository. Or you can add to your sorting field "userProfile.datecreated" instead of "datecreated" and see if this solve your problem.

3 - Don't hide the error message. Probably if I had seen it, I could help you more.

Answer 3

This is a little old, but I will put here to allow future references.

You ca use JPQL (that allow pageable ) or NATIVE QUERY (require more work):

1. JPQL (in this case the pagination is very easy):

@Query(value = "SELECT u FROM User u ORDER BY id")
Page<User> findAllUsersWithPagination(Pageable pageable);

2. Native queries:

@Query(
  value = "SELECT * FROM Users ORDER BY id", 
  countQuery = "SELECT count(*) FROM Users", 
  nativeQuery = true)
Page<User> findAllUsersWithPagination(Pageable pageable);

I got this code from Baeldung .
