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.

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 : ]

I am using Hibernate version - 5.4.12.Final and mysql-connector-java driver version - 8.0.18.
My entities:
#Entity
public class Author {
#Id
private long id;
#OneToMany(mappedBy = "author", fetch = FetchType.LAZY)
private Set<Post> posts = new HashSet<>();
//Getters and setters...
}
#Entity
public class Post {
#Id
private long id;
#ManyToOne(cascade = {CascadeType.MERGE, CascadeType.PERSIST}, fetch = FetchType.LAZY)
#JoinColumn(name = "author_id")
private Author author;
#OneToMany(mappedBy = "post", fetch = FetchType.LAZY, cascade = {CascadeType.REMOVE, CascadeType.REFRESH, CascadeType.DETACH}, orphanRemoval = true)
private List<PostComment> postComments = new ArrayList<>();
//Getters and setters...
}
#Entity
public class PostComment {
#Id
private long id;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "post_id")
private Post post;
//Getters and setters...
}
When I run this JPQL query:
SELECT post FROM Post post
LEFT JOIN FETCH post.author author
LEFT JOIN FETCH post.postComments postComments
WHERE author.id = :authorId
Then this error appears:

But when I run this query then there is no errors:
SELECT post FROM Post post
LEFT JOIN FETCH post.author author
LEFT JOIN post.postComments postComments
WHERE author.id = :authorId
Questions:
Why am I not able to use FETCH JOIN?
Why does this error appear here?
How can I fix it?
The problem was in streaming result set. In order to fix it need to replace this code:
return query.getResultStream().collect(Collectors.toSet());
with such code:
return new HashSet<>(query.getResultList());
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;
}
I went through the URL: https://www.baeldung.com/spring-boot-mongodb-auto-generated-field and How can we create Auto generated field for mongodb using spring boot code and suggestions works very well.
But when I changed
#Id
private long id;
To
#Id
private Long id;
Then code doesn't works and give below error.

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:

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:

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;
}
I'm working on a academic project with Spring + MongoDB
I have three Document
User.java
#Document
public class User implements UserDetails, Serializable {
private static final long SerialVersionUID = 147147L;
#Id
private String id;
private String username;
private String password;
private String firstname;
private String lastname;
private String email;
private String phone;
private boolean enable = true;
private Set<UserRole> userRoles = new HashSet<>();
...
}
Role.java
#Document
public class Role implements Serializable {
private static final long SerialVersionUID = 456456L;
#Id
private String id;
private String name;
...
}
UserRole.java
#Document(collection = "user_roles")
public class UserRole implements Serializable {
private static final long SerialVersionUID = 789789L;
#Id
private String id;
#DBRef
private User user;
#DBRef
private Role role;
private String name;
...
}
And a UserServiceImpl.java
#Service
public class UserServiceImpl implements UserService {
private static final Logger LOG = LoggerFactory.getLogger(UserService.class);
#Autowired
UserRepository userRepository;
#Autowired
RoleRepository roleRepository;
#Autowired
UserRoleRepository userRoleRepository;
#Override
public User createUser(User user, Set<UserRole> userRoles) {
User localUser = userRepository.findByUsername(user.getUsername());
if(localUser != null) {
LOG.info("User with username {} already exist. Nothing will be done. ", user.getUsername());
} else {
for (UserRole ur : userRoles) {
roleRepository.save(ur.getRole());
//here is the problem: the userrole instance created cannot generate Id
userRoleRepository.save(ur);
}
user.getUserRoles().addAll(userRoles);
localUser = userRepository.save(user);
}
return localUser;
}
}
and the DemoApplication.java
#SpringBootApplication
public class DemoApplication implements CommandLineRunner {

Here I dont't know why roles and users instance can generate automatically but userrole cannot. The console return me an exception that the Id is NULL and cannot be reference.
I'm new for this, and I hope someone could give me an answer.
thanks.
It seems that you are calling userRoleRepository.save(ur) in case when the User with the provided username does not exist in the database and before actually storing this User in it.
I believe you should reorganise your code in a way to store the User first and then store the UserRole with this User set.
In other words (code?), in your UserServiceImpl you could try doing something like this:
#Override
public User createUser(User user, Set<UserRole> userRoles) {
User localUser = userRepository.findByUsername(user.getUsername());
if(localUser != null) {
LOG.info("User with username {} already exist. Nothing will be done. ", user.getUsername());
} else {
user.getUserRoles().addAll(userRoles);
localUser = userRepository.save(user);
for (UserRole ur : userRoles) {
roleRepository.save(ur.getRole());
userRoleRepository.save(ur);
}
}
return localUser;
}
As you can see, I have only reordered the calls - User is stored first, then go the userRoles for this User.
