Spring data jpa@query and pageable

Rewrite your query to:

select iu from internal_uddi iu where iu.urn....

最佳答案

A similar question was asked on the Spring forums, where it was pointed out that to apply pagination, a second subquery must be derived. Because the subquery is referring to the same fields, you need to ensure that your query uses aliases for the entities/tables it refers to. This means that where you wrote:

select * from internal_uddi where urn like

You should instead have:

select * from internal_uddi iu where iu.urn like ...

Considering that the UrnMapping class is mapped to the internal_uddi table, I would suggest this:

@Repository
public interface UrnMappingRepository extends JpaRepository<UrnMapping, Long> {


@Query(value = "select iu from UrnMapping iu where iu.urn like %:text% or iu.contact like %:text%")
Page<UrnMapping> fullTextSearch(@Param("text") String text, Pageable pageable);
}

Please note that you might have to turn off native queries with dynamic requests.

You can use pagination with a native query. It is documented here: Spring Data JPA - Reference Documentation

"You can however use native queries for pagination by specifying the count query yourself: Example 59. Declare native count queries for pagination at the query method using @Query"

public interface UserRepository extends JpaRepository<User, Long> {


@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}

Please reference :Spring Data JPA @Query, if you are using Spring Data JPA version 2.0.4 and later. Sample like below:

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

I found it works different among different jpa versions, for debug, you'd better add this configurations to show generated sql, it will save your time a lot !

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

for spring boot 2.1.6.RELEASE, it works good!

Sort sort = new Sort(Sort.Direction.DESC, "column_name");
int pageNumber = 3, pageSize = 5;
Pageable pageable = PageRequest.of(pageNumber - 1, pageSize, sort);

@Query(value = "select * from integrity_score_view " +
"where (?1 is null or data_hour >= ?1 ) " +
"and (?2 is null or data_hour <= ?2 ) " +
"and (?3 is null or ?3 = '' or park_no = ?3 ) " +
"group by park_name, data_hour ",
countQuery = "select count(*) from integrity_score_view " +
"where (?1 is null or data_hour >= ?1 ) " +
"and (?2 is null or data_hour <= ?2 ) " +
"and (?3 is null or ?3 = '' or park_no = ?3 ) " +
"group by park_name, data_hour",
nativeQuery = true
)
Page<IntegrityScoreView> queryParkView(Date from, Date to, String parkNo, Pageable pageable);

you DO NOT write order by and limit, it generates the right sql

With @Query , we can use pagination as well where you need to pass object of Pageable class at end of JPA method

For example:

Pageable pageableRequest = new PageRequest(page, size, Sort.Direction.DESC, rollNo);

Where, page = index of page (index start from zero)
size = No. of records
Sort.Direction = Sorting as per rollNo
rollNo = Field in User class

UserRepository repo
repo.findByFirstname("John", pageableRequest);


public interface UserRepository extends JpaRepository<User, Long> {


@Query(value = "SELECT * FROM USER WHERE FIRSTNAME = :firstname)
Page<User> findByLastname(@Param("firstname") String firstname, Pageable pageable);
}

小开

Declare native count queries for pagination at the query method by using @Query

public interface UserRepository extends JpaRepository<User, Long> {


@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);


}

Hope this helps

I tried all above solution and non worked , finally I removed the Sorting from Pagination and it worked

I had the same issue - without Pageable method works fine.
When added as method parameter - doesn't work.

After playing with DB console and native query support came up to decision that method works like it should. However, only for upper case letters.
Logic of my application was that all names of entity starts from upper case letters.

Playing a little bit with it. And discover that IgnoreCase at method name do the "magic" and here is working solution:

public interface EmployeeRepository
extends PagingAndSortingRepository<Employee, Integer> {


Page<Employee> findAllByNameIgnoreCaseStartsWith(String name, Pageable pageable);


}

Where entity looks like:

@Data
@Entity
@Table(name = "tblEmployees")
public class Employee {


@Id
@Column(name = "empID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;


@NotEmpty
@Size(min = 2, max = 20)
@Column(name = "empName", length = 25)
private String name;


@Column(name = "empActive")
private Boolean active;


@ManyToOne
@JoinColumn(name = "emp_dpID")
private Department department;
}

the following tutorial helped me -> https://www.baeldung.com/spring-data-jpa-query

At this point 4.3. Spring Data JPA Versions Prior to 2.0.4

VERY IMPORTANT to add \ n-- #pageable \ n Without this I was wrong

Also the pagination setting must be without ordering

PageRequest paginaConf = new PageRequest ((param1 - 1)
, param2);

Finally to convert the Page <Object []>

  Page <Object []> list = myQueryofRepo ();
List <XXXModel> lstReturn = myConversor (list.getContent ());
Page <XXXModel> ret = new PageImpl <XXXModel> (lstReturn, pageConf, param2);

When using nativeQuery that is having (nativeQuery = true), you may do the pagination yourself in the query by adding (LIMIT :sizeValue OFFSET :page)

Note: Your page value passed to this method should be offset * size

Example

 @Query(value = "SELECT * FROM person " +
"LIMIT ?1 OFFSET ?2", nativeQuery = true)
Optional<List<TDriverJob>> findPersons(int size, int page);
