I am using Spring JPA and postgres database. I have created the following table:
CREATE TABLE public.book
(
id bigint NOT NULL DEFAULT nextval('book_id_seq'::regclass),
title character varying(60) NOT NULL,
year date,
publisher character varying(30),
author bigint[] NOT NULL,
cathegory smallint[],
CONSTRAINT book_primary_key PRIMARY KEY (id)
)
Here is DAO:
#Data
#NoArgsConstructor
#Entity
#Table(name = "book", schema = "public")
public class BookDao {
#Id
#GeneratedValue(strategy = GenerationType.AUTO, generator = "auto_gen_book")
#SequenceGenerator(name = "auto_gen_book", sequenceName = "book_id_seq", allocationSize = 1)
private Long id;
private String title;
private LocalDateTime year;
private String publisher;
private long[] author;
private short[] cathegory;
public BookDao(String title, long[] author, short[] cathegory) {
this.title = title;
this.author = author;
this.cathegory = cathegory;
}
}
Here is a very simple controller:
#RestController
#RequestMapping("/book")
public class BookController {
#Autowired
BookService bookService;
#RequestMapping("/{id}")
public String getUserSurnameFromId(#PathVariable long id) {
return bookService.getBookById(id).toString();
}
#RequestMapping("/all")
public List<BookDao> getAllBooks() {
return bookService.getAllBooks();
}
#RequestMapping("/save/{title}/{author}/{category}")
public BookDao saveByTitleAuthorCategory(#PathVariable String title, #PathVariable long author, #PathVariable short category) {
long[] authors = {author};
short[] categories = {category};
BookDao bookDao = new BookDao(title, authors, categories);
return bookService.save(bookDao);
}
}
I the controller service is used, but the only thing it does is invoking repository methods. No logic is yet implemented.
The problem occurs, when I am connecting to http://localhost:8090/book/all to list all records, I am getting following error:
2018-03-15 22:40:33.291 ERROR 8022 --- [nio-8090-exec-6] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize] with root cause

In addition to that, I am using spring jpa to represent the following table:
CREATE TABLE public."user"
(
id bigint NOT NULL DEFAULT nextval('user_id_seq'::regclass),
surname character varying(30) NOT NULL,
name character varying(30) NOT NULL,
date_of_birth date,
place_of_birth character varying(30),
CONSTRAINT user_primary_key PRIMARY KEY (id)
)
This indicates no error at all, although everything is practically the same.
For me, the main difference is in using tables in definition of columns in postgres, but after long hours of thinking and researching I couldn't find any other clue. I will be thankful for any help.
Just like #jeff-wang has pointed out, Postgres array types are not supported by JPA. Specific mapping implementations can be added manually, but #vlad-mihalcea has already provided sample implementation. You get it from maven central:
<dependency>
<groupId>com.vladmihalcea</groupId>
<artifactId>hibernate-types-52</artifactId>
<version>${hibernate-types.version}</version>
</dependency>
More details can be found here: https://vladmihalcea.com/how-to-map-java-and-sql-arrays-with-jpa-and-hibernate/
After resolving the dependency, an implementation for specific mapping needs to be added. Let us take Postgres bigint[] as an example. It can be mapped to for example Long[]. Firstly, we need to add descriptor for desired type:
import com.vladmihalcea.hibernate.type.array.internal.AbstractArrayTypeDescriptor;
public class LongArrayTypeDescriptor extends AbstractArrayTypeDescriptor<Long[]> {
public static final LongArrayTypeDescriptor INSTANCE = new LongArrayTypeDescriptor();
public LongArrayTypeDescriptor() {
super(Long[].class);
}
protected String getSqlArrayType() {
return "bigint";
}
}
After that the actual mapping class:
import com.vladmihalcea.hibernate.type.array.internal.ArraySqlTypeDescriptor;
import org.hibernate.type.AbstractSingleColumnStandardBasicType;
import org.hibernate.usertype.DynamicParameterizedType;
import java.util.Properties;
public class LongArrayType extends AbstractSingleColumnStandardBasicType<Long[]> implements DynamicParameterizedType {
public static final LongArrayType INSTANCE = new LongArrayType();
public LongArrayType() {
super(ArraySqlTypeDescriptor.INSTANCE, LongArrayTypeDescriptor.INSTANCE);
}
public String getName() {
return "long-array";
}
#Override
protected boolean registerUnderJavaType() {
return true;
}
#Override
public void setParameterValues(Properties parameters) {
((LongArrayTypeDescriptor) getJavaTypeDescriptor()).setParameterValues(parameters);
}
}
That being done, all that is left to do is to take our mappings into account in Spring configuration. I am keeping my data model configuration separately in annotation based form:
import ibdb.model.mappers.LongArrayType;
import ibdb.model.mappers.ShortArrayType;
import org.hibernate.annotations.TypeDef;
import org.hibernate.annotations.TypeDefs;
import javax.persistence.MappedSuperclass;
#TypeDefs({
#TypeDef(
name = "long-array",
typeClass = LongArrayType.class
),
#TypeDef(
name = "short-array",
typeClass = ShortArrayType.class
)
})
#MappedSuperclass
public class DaoConfig {
}
Now everything is ready to use. Example column annotated with newly added mapping in DAO definition looks like following:
#Type(
type = "long-array"
)
#Column(
columnDefinition = "bigint[]"
)
private Long[] author;
The issue here is that Postgres array types are not by default supported by JPA. you will need to create a usertype, like the answer in this question How to use Spring Data / JPA to insert into a Postgres Array type column?
In addition, you may want to check your model, because these arrays (assuming they are id's of authors and categories) violate the 1st normal form. See https://en.wikipedia.org/wiki/First_normal_form Normally for a mapping like this, you would have many to many with a associative table in the middle.

I tried to create a restful API by using spring boot and MySQL in IntelliJ idea. but I got the following error. and I tried to use #Column(name = "last_name") annotation for the Student.java model. but it not succeed. I my MySQL table i used column names by using camel case. but the error shows as Unknown column student_id.

My application.properties ile be like this.
spring.jpa.hibernate.ddl-auto=none
spring.datasource.url=jdbc:mysql://localhost:3306/tution?user=root&password=19940306
I created a database as tuition and create a table as Student as follows.
So what is the reason for this error?
The exception suggests, the query is looking for column 'student_id' and your table has column with name 'studentId'.
You may either annotate column name in your entity like #Column(name="studentId") or recreate table with changed column name (note same will apply to other columns).
You may get a little more and relevant information here and here
You got this error because you are using camelCase.
private int studentId;
private String firstName;
private String lastName;
Instead you can use:
private int studentid;
private String firstname;
private String lastname;
If you want to make use of different name for your field you can make use of #Column
Note: Changing the field name to #Column(name = "studentId") will give you the same error.
I'm getting an exception: More than one row with the given identifier was found, when I try to get a single record from the database with the findById() method or when I try to update an article with Spring Data Rest.
The delete and findAll methods are working properly.
I checked the database already, there are no multiple records with same id. Also id is an unique key in the database. I have seen many people with the same error, but with this people the problem was that they where using joins. I don't have any joins.

Try using GenerationType.SEQUENCE instead of GenerationType.IDENTITY. Some databases like PostgreSQL don't support IDENTITY.
Okay, you said I checked the database already, there are no multiple records with same id. this is strange.As you have mentioned findById() will return only one record.We will give it a try by fetching the same data with below.
#Repository
public interface ArticleRepository extends JpaRepository<Article, Long> {
#Query("select a from Article a where a.id = :id")
List<Article> getArticleById(#Param("id") long id);
}
Let me know what happened.
I am coding a blog application and I have a problem with the Hibernate. Problem occurs when I have 2 rows in my User table with the same role_id. After adding a third user with that same id, exception is thrown.
I've tried to set Lazy init. but it doesen't seems to work.
Here is my User class.
#NoArgsConstructor
#Getter
#Setter
#Entity
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String username;
private String password;
private String email;
private String dateCreated;
private String createdBy;
private String dateModified;
private String modifiedBy;
#Transient
private Position position;
#ManyToMany(mappedBy = "users", cascade = CascadeType.ALL)
private Set<Blog> blogs = new HashSet<>();
#OneToMany(mappedBy = "user")
private Set<Post> posts = new HashSet<Post>();
#OneToMany(mappedBy = "user")
private Set<Comment> comments = new HashSet<Comment>();
#OneToOne
#JoinColumn(name = "role_id")
private Role role;
}
Here is my Role class.
#NoArgsConstructor
#Getter
#Setter
#Entity
public class Role {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#Enumerated(EnumType.STRING)
private Position position;
#OneToOne(mappedBy = "role")
private User user;
}
Block of code where excpetion occurs.
#Override
public Set<Role> getAllRoles() {
Iterable<Role> source = roleRepositorium.findAll(); // exception is thrown here
Set<Role> roles = new HashSet<>();
source.forEach(r -> roleToRoleCommand.convert(r));
source.forEach(roles::add);
return roles;
}
Error message.

You should use #ManyToOne and #OneToMany annotations instead if an user has a single role but one role can belong to one or more users
Check this tutorial:
https://www.baeldung.com/hibernate-one-to-many
Also, here are some useful thoughts on thinkins these relations between entities:
https://thoughts-on-java.org/best-practices-many-one-one-many-associations-mappings/
The problem is that you have mapped Role and User as one to one when in reality there can be many users who have the same role and in fact, contrary to the above answer, usually many roles that a single user can have.
In your case Role is mapped one to one to User so when hibernate loads that entity from the DB, it sees that there are more than 1 result associated with it and finds an exception. That's the exception you're seeing.
You actually want to be using #ManyToMany if a User can have multiple Roles and of course the same Role can belong to many users.
I am trying to persist a category into a category table however i get this error : ERROR: subquery in FROM must have an alias . This error only happens when i am using Postgres , when i used H2 in memory database it worked fine.
This is my code :
AbstractEntity
#MappedSuperclass
public class AbstractEntity {
#Id
#GeneratedValue
private Long id;
#Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null || this.getClass() != obj.getClass()) {
return false;
}
return Objects.equals(this.id, AbstractEntity.class.cast(obj).id);
}
#Override
public int hashCode() {
return Objects.hashCode(id);
}
// getters and setter ommitted for brevity
}
Category Entity
#Entity
#Table(name = "app_category")
public class Category extends AbstractEntity {
#Column(name = "name", nullable = false)
private String name;
#ManyToOne
#JoinColumn(name = "parentid")
private Category parent;
#ManyToMany(fetch = FetchType.LAZY, mappedBy = "categories")
private Set<Product> products;
#OneToMany(mappedBy = "parent")
private Set<Category> childCategories;
// getters and setter ommitted for brevity
}
CategoryRepository
#Repository
public interface CategoryRepository extends JpaRepository<Category, Long> {
String GET_RECURSIVELY_ALL_SUBCATEGORIES_SQL =
"WITH RECURSIVE ALL_SUBCATEGORIES(ID, PARENTID)
AS
(select c.id, c.parentid
from app_category c where c.parentid is null
union all select c.id, c.parentid
from ALL_SUBCATEGORIES
inner join app_category c on ALL_SUBCATEGORIES.id = c.parentid) select id, parentid
from ALL_SUBCATEGORIES";
}
CategoryService
#Transactional
#Override
public Category createCategory(String name) {
Category category = new Category();
category.setName(name);
return categoryRepository.save(category);
}
CategoryController
#RequestMapping(method = RequestMethod.POST)
#ApiOperation(value = "", authorizations = { #Authorization(value="apiKey") })
public ResponseEntity<?> createCategory(#RequestBody #Valid CategoryDto request) {
final Category category = categoryService.createCategory(request.getName());
return ResponseEntity.status(HttpStatus.CREATED).body(categoryResourceAssembler.toResource(category));
}
When i try to create a category i get this error on swagger :
could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
The stacktrace also prints the following:

H2 isn't Postgres, even in compatibility mode. It's a great little system, but it still only implements a subset of the stuff that Postgres does.
Off-hand, I suspect this is exactly what the error message says - lack of an alias on the subquery, which the SQL standard does not allow. Postgres tends to be pretty strict about following the standard.
More specifically, there is no alias on SUB_CATEGORIES inside the WITH which is (probably) your problem.
WITH RECURSIVE all_subcategories(id, parentid) AS (
SELECT c.id, c.parentid
FROM app_category c
WHERE c.parentid is null
UNION ALL
SELECT c.id, c.parentid
FROM all_subcategories sc
INNER JOIN app_category c ON sc.id = c.parentid
)
SELECT id, parentid
FROM all_subcategories;
I suspect the above should work (assuming I didn't add any typos).
Trying to create a simple SpringBoot application - Api with DataBase, using Gradle. When trying to get data from the Table, using api call, getting an exception in a Postman:
{
"timestamp": "2018-04-01T12:45:40.218+0000",
"status": 500,
"error": "Internal Server Error",
"message": "could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet",
"path": "/api/demo/towns"
}
In the Idea having next exception:

I see that problem is with the CountryCode column, but don't understand, what is with it.
Using MySql DB, one table. It's structure:
Main entity:
#Entity
#Table(name="city")
public class City implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name="Name")
private String name;
#Column(name="CountryCode")
private String countryCode;
#Column(name="District")
private String district;
#Column(name="Population")
private int population;
public int getId(){
return id;
}
public void setId(int id){
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCountryCode() {
return countryCode;
}
public void setCountryCode(String countryCode) {
this.countryCode = countryCode;
}
public String getDistrict() {
return district;
}
public void setDistrict(String district) {
this.district = district;
}
public int getPopulation() {
return population;
}
public void setPopulation(int population) {
this.population = population;
}
public City(String name, String countryCode, String district, int population){
this.name = name;
this.countryCode = countryCode;
this.district = district;
this.population = population;
}
public City(){
}
}
Repository:
#Repository("cityRepository")
public interface CityRepository extends CrudRepository<City, Integer> {
}
Controller:
#RestController
#RequestMapping("/api/demo")
public class DemoController {
#Autowired
#Qualifier("cityRepository")
private CityRepository cityRepository;
#RequestMapping(value = "towns",
method = RequestMethod.GET,
produces = {MimeTypeUtils.APPLICATION_JSON_VALUE},
headers = "Accept=application/json")
public ResponseEntity<Iterable<City>> getTowns() {
Iterable<City> list = cityRepository.findAll();
return new ResponseEntity<Iterable<City>>(list, HttpStatus.OK);
}
}
Thanks to #JB Nizet answer, after I added property: spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl into application.property file, all is working. Thanks.
