How to select referenced entities with Spring Data JDBC - java

How to select referenced entities in One-To-May relationship with Spring Data JDBC?
When I tried following code on this blog
class PurchaseOrder {
#Id
private Long id;
private String shippingAddress;
private Set<OrderItem> items;
}
class OrderItem {
#Id
private Long id;
private int quantity;
private String product;
}
#Test
void test() {
PurchaseOrder purchaseOrder = PurchaseOrder.of("Tokyo");
purchaseOrder.addItem(4, "Captain Future Comet Lego set");
purchaseOrder.addItem(2, "Cute blue angler fish plush toy");
orderRepository.save(purchaseOrder);
Iterable<PurchaseOrder> result = orderRepository.findAll(); //throw MappingException !!
result.forEach(System.out::println);
}
this throws an exception below:
org.springframework.data.mapping.MappingException: Could not read property #org.springframework.data.annotation.Id()private final java.lang.Long com.example.demo.OrderItem.id from result set!
at org.springframework.data.jdbc.core.EntityRowMapper.readFrom(EntityRowMapper.java:130)

at org.springframework.data.jdbc.core.EntityRowMapper.lambda$createInstance$0(EntityRowMapper.java:167)
......
Caused by: org.h2.jdbc.JdbcSQLException: Column "items_id" not found [42122-197]
at org.h2.message.DbException.getJdbcSQLException(DbException.java:357)
at org.h2.message.DbException.get(DbException.java:179)
at org.h2.message.DbException.get(DbException.java:155)
......
It looks that spring data jdbc add the parent entity's name as prefix to columns of child entities when retrieving values from ResultSet. But I couldn't this mapping rule on the document...
Is there any way to custom this mapping rule?
DDL:
create table purchase_order (
id bigint primary key auto_increment,
shipping_address varchar NOT NULL
);
create table order_item (
id bigint primary key auto_increment,
purchase_order bigint NOT NULL,
quantity int NOT NULL,
product varchar NOT NULL
);
[UPDATED]
The version of spring-data-jdbc is 1.0.4.RELEASE.
The SQL statements is here:
2019-01-29 23:49:16.932 DEBUG 80409 --- [ main] o.s.jdbc.core.JdbcTemplate : Executing prepared SQL statement [SELECT purchase_order.id AS id, purchase_order.shipping_address AS shipping_address FROM purchase_order]
And full stack trace is

Following copied from official docs.
To wrap it up: Spring Data JDBC does not support many-to-one or many-to-many relationships. In order to model these, use IDs. This encourages a clean modularization of the domain model. It also removes a whole type of questions that one would have to solve and learn to reason about if such a mapping were possible.
class PurchaseOrder {
#Id
private Long id;
private String shippingAddress;
private Set<OrderItem> items;
private OrderItemRef createOrderItem(OrderItem orderItem ) {
OrderItemRef orderItemRef = new OrderItemRef ();
orderItemRef.orderItem = orderItemRef.id;
return orderItemRef ;
}
}
#Table("Purchase_OrderItem ")
class OrderItemRef {
Long orderItem;
}
class OrderItem {
#Id
private Long id;
private int quantity;
private String product;
}

Springboot Data JPA 2.4.6 JUnit Test case Failing with Function "TOP" not found

I have the below code in my SpringBoot(2.4.6) and Java 11 project
public class EmployeeRepositoryImpl implements CustomEmployeeRepository {
private EntityManager entityManager;
private Querydsl querydsl;
private QEmployee queryEmployee;
public EmployeeRepositoryImpl(#Qualifier("tenantEntityManagerFactory") EntityManager entityManager) {
this.entityManager = entityManager;
this.querydsl = new Querydsl(entityManager, (new PathBuilderFactory()).create(Employee.class));
this.queryEmployee = QEmployee.Employee;
}
#Override
public Page<Employee> getEmployeesWithOrgs(Predicate predicate, Pageable pageable, List<UUID> orgIds) {
JPQLQuery<Employee> query = new JPAQuery<>(entityManager);
BooleanBuilder whereClause = new BooleanBuilder();
query.select(queryEmployee).from(queryEmployee);
query.leftJoin(QEmployeeOrganization.EmployeeOrganization)
.on(QEmployeeOrganization.EmployeeOrganization.Employee.eq(QEmployee.Employee));
whereClause.or(QEmployeeOrganization.EmployeeOrganization.id.organizationId.in(orgIds));
whereClause.or(QEmployeeOrganization.EmployeeOrganization.id.organizationId.isNull());
query.where(whereClause).distinct();
Long totalElements = query.fetchCount();
List<Employee> result = querydsl.applyPagination(pageable, query).fetch();
return new PageImpl<>(result, pageable, totalElements);
}
}
#Test
public void testGetEmployeesWithOrgs() {
UUID EmployeeGuid1 = UUID.randomUUID();
UUID EmployeeGuid2 = UUID.randomUUID();
UUID orgGuid1 = UUID.randomUUID();
UUID EmployeeGuid3 = UUID.randomUUID();
UUID orgGuid2 = UUID.randomUUID();
Employee org1Employee1 = EmployeeBuilder.aEmployee().withVersion(1L).withEmployeeStatus(EmployeeStatus.ACTIVE).withGuid(EmployeeGuid1).withOrganizations(Arrays.asList(orgGuid1)).build();
EmployeeRepository.save(org1Employee1);
Employee org1Employee2 = EmployeeBuilder.aEmployee().withVersion(1L).withEmployeeStatus(EmployeeStatus.ACTIVE).withGuid(EmployeeGuid2).withOrganizations(Arrays.asList(orgGuid1)).build();
EmployeeRepository.save(org1Employee2);
Employee org2Employee1 = EmployeeBuilder.aEmployee().withVersion(1L).withEmployeeStatus(EmployeeStatus.ACTIVE).withGuid(EmployeeGuid3).withOrganizations(Arrays.asList(orgGuid2)).build();
EmployeeRepository.save(org2Employee1);
Page<Employee> latestVersionOfAllEmployees = employeeRepository.getEmployeesWithOrgs(null, PageRequest.of(0, 10), Arrays.asList(orgGuid1));
Assert.assertNotNull(latestVersionOfAllEmployees);
Assert.assertEquals(2,latestVersionOfAllEmployees.getContent().size());
}
Above code is wokring fine in my application but when I run the test case its failing with below error, seems like the issue is generated Query has Top keyword which is not a valid function in H2(1.4.196) . If I remove .distinct() then the test case is passed. Is this a bug? or is there any workaround for this?

What is causing this issue? What is mean by Fail to convert to internal representation ?
How to overcome this?

Your problem must be related to Fail to convert to internal representation. You must be making some mistake in the mapping between your entity and DB table. Refer the following link java.sql.SQLException: Fail to convert to internal representation

Populating database with test data during integration tests with Spring Boot

I'm trying to build simple CRUD with Spring Boot. Spring Data Jpa is used to deal with persistence.
Here are my entities
#Entity(name = "meal")
#Table(name = "meals")
public class Meal extends AbstractBaseEntity {
#Column(name = "name", nullable = false)
private String name;
#Column(name = "cost", nullable = false)
private BigDecimal cost;
#Column(name = "cooking_time", nullable = false)
private Duration cookingTime;
...
getters, setters and constructors omitted
#Entity(name = "order")
#Table(name = "orders")
public class Order extends AbstractBaseEntity {
#Column(name = "total_cooking_time", nullable = false)
private Duration totalCookingTime;
#Column(name = "total_cost", nullable = false)
private BigDecimal totalCost;
...
superclass, which contains generated id looks like this
#MappedSuperclass
public abstract class AbstractBaseEntity {
#Id
#GeneratedValue
protected Long id;
...
Also i'm using JPA 2.1 scheme auto generation with H2 in memory database.
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:restaurant
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
spring.h2.console.enabled=true
And i have data.sql file in my project resources folder to populate db with test data. Here how it looks.
INSERT INTO meals VALUES (1, 900000000000, 122.5, 'Soup');
INSERT INTO meals VALUES (2, 1800000000000, 155.5, 'Stake');
Everything works fine when i run it with SpringApplication class. Tables gets created and populated. But when i'm trying to run tests - all modifying methods, fails with DataIntegrityViolationException due to primary key uniqueness constraint violation. It looks like it is trying to populate database with test data twice. I'm using Spring Data repositories to acces data.
#Repository
public interface MealJpaRepository
extends JpaRepository<Meal, Long> {
}
My test class looks like this.
#SpringBootTest
#DirtiesContext(classMode = DirtiesContext.ClassMode.BEFORE_EACH_TEST_METHOD)
public class RestaurantApplicationTest {
#Autowired
MealJpaRepository repository;
#Test
void getAll() {
assertEquals(repository.findAll().size(), 2);
}
#Test
void getById() {
assertNotNull(repository.findById(1L));
}
#Test
void create() {
Meal fish = new Meal("Fish", new BigDecimal("250.0"), Duration.ofMinutes(13));
repository.save(fish);
assertTrue(repository.findAll().stream()
.anyMatch(meal -> meal.getName().equals("Fish") && meal.getCost().equals(new BigDecimal("250.0"))));
}

As i have already mentioned - get methods succeed, speaking of create method - here is my stacktrace.

Caused by: org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Unique index or primary key violation: "PRIMARY KEY ON PUBLIC.MEALS(ID) [1, 900000000000, 122.50, 'Soup']"; SQL statement:
insert into meals (cooking_time, cost, name, id) values (?, ?, ?, ?) [23505-200]
Original idea was to reinitialize and repopulate database before every test method.
What am i doing wrong?

If you look at the logs:
Hibernate: create sequence hibernate_sequence start with 1 increment by 1
create table meals (id bigint not null, ...)
Hibernate: call next value for hibernate_sequence
Hibernate: insert into meals (cooking_time, cost, name, id) values (?, ?, ?, ?)
Since the next value for sequence is 1 and the record with id value 1 is already saved ((1, 900000000000, 122.5, 'Soup')), it throws DataIntegrityViolationException
To fix the issue, you don't need to change the sql script and use the id values 100, 200. You need to set the id generation strategy to GenerationType.IDENTITY.
If you use GenerationType.IDENTITY
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
protected Long id;
the logs generated:
Hibernate: create table meals (id bigint generated by default as identity, ...)
Hibernate: insert into meals (id, cooking_time, cost, name) values (null, ?, ?, ?)
Hibernate will use the automatically incremented value based on the id column. Since the last saved ids are 1 and 2, the next value will be 3.
You can see by simply adding a print statement:
repository.save(fish);
System.out.println("id of fish: " + fish.getId());
Output:
id of fish: 3
If you try with saving ids 100 and 200 on data.sql, then you'll see the output:
id of fish: 201
PS: #SpringBootTest loads the full application context. #DataJpaTest which loads only JPA related components, would be a better choice to test JPA repositories.

repopulate database before every test method
Did you drop all data, clean up after each test ? Cause it is saying
Unique index or primary key violation: "PRIMARY KEY ON PUBLIC.MEALS(ID) [1, 900000000000, 122.50, 'Soup']"
Also mind if you let the tests run sequential or parallel.

You can annotate your test suites with #Transactional. It means that every test method in your suite is surrounded by an overarching Spring transaction. This transaction will be rolled back at the end of the test method regardless of it's outcome.

Doing some debug i found out the problem was that database id generating sequence knew nothing about data i inserted. So, when hibernate was trying to get next value from the sequence - it was 1. And a row with such id already existed in database.
Hibernate: call next value for hibernate_sequence
Hibernate: insert into meals (cooking_time, cost, name, id) values (?, ?, ?, ?)
2021-02-27 15:17:02.998 WARN 10168 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: -104, SQLState: 23505

And this crude temporary solutions proves my guess.
I have changed sql script this way and it works like intended now. But, of course, i must investigate further and let database generate id's for test data automatically.
INSERT INTO meals (id, cooking_time, cost, name) VALUES (100, 900000000000, 122.5, 'Soup');
INSERT INTO meals (id, cooking_time, cost, name) VALUES (200, 1800000000000, 155.5, 'Stake');

Failing to persist data with spring JpaRepository

Ive created a simple 3 entities data model and when trying to persist data its not working.
Here are the entities and their id classes, server:
#Entity
#Data
public class Server {
#Id
private String name;
private String serverUrl;
#OneToMany(mappedBy = "server", fetch = FetchType.LAZY)
private List<Service> services;
}
Service:
#Entity
#IdClass(ServiceId.class)
public class Service {
#Id
private String name;
#Id
#ManyToOne(fetch = FetchType.LAZY)
private Server server;
#OneToMany(mappedBy = "service", fetch = FetchType.EAGER)
private List<Container> containers;
}
public class ServiceId implements Serializable {
private String name;
private Server server;
}
Container:
#Entity
#IdClass(ContainerId.class)
public class Container {
#Id
private String name;
#Id
#ManyToOne(fetch = FetchType.LAZY)
private Service service;
private String command;
private String state;
private String ports;
}
#Data
public class ContainerId implements Serializable {
private String name;
private Service service;
}
What im trying to do is using ServiceRepository:
public interface ServiceRepository extends JpaRepository<Service, ServiceId> {
}
to persist a service object:
public class SomeClass{
#Autowired
ServiceRepository serviceRepository;
#Transactional
public void insertServices(Service service) {
serviceRepository.save(service); <- Exception HERE!
}
}
The service object contain a Server which is already in the DB at server table, the service itself which is not in the db yet and a list of containers which are not in the db yet(and should also be persistant now).
The error im getting when doing that is:
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'a.servers.Server' for property 'server'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'a.servers.Server' for property 'server': no matching editors or conversion strategy found

i have spring -> jpa -> show-sql set to true in application.yml so i do get this log before it fails:
Hibernate: select server0_.name as name1_1_, server0_.server_url as server_u2_1_ from server server0_
Created DB seems ok:

I also had problems with a similar composite key in my current project.
Maybe I'm wrong, but for me it seems that #IdClass only works if none of the #Id annotated properties are foreign keys.
I finally refactored my entities by using #EmbeddedId instead.
...
Actually I have one more idea: try adding the #ManyToOne annotation to server property in the ServiceId class too:
public class ServiceId implements Serializable {
private String name;
#OneToMany(mappedBy = "service", fetch = FetchType.EAGER)
private Server server;
}

Spring boot rest API - Querydsl, predicate must not be null

Is the Predicate supposed to be nullable using MongoRepository?
The standard JPA PagingAndSortingRepository always seems to return a valid Predicate, no matter which query parameters are provided.

Add an extra check
if (predicate == null) {
predicate = QNotification.notification.id.ne("");
}
return notificationRepository.findAll(predicate, pageable);

my problem was sorted out by a new compiler plugin block in pom.xml with lombok-mapstruct-binding, not to generate mapstruct before lombok getters setters have been done - special thx for my teacher # BME for the solution : ]
