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 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());
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.

I have two entities, UploadEntity and UploadStoreEntity. These map to tables u_upload and us_upload_store. Table u_upload contains a foreign key reference to us_upload_store, called us_id.
I recently added a NOT NULL constraint to the us_id column, so I'm trying to ensure this field is populated in uploadEntity in the code below, before flushing to the database. However, it is failing as it is not populated upon flushing, even though uploadStoreEntity.getId() returns a non-null value. Please could somebody help me understand why?
public IUpload putUpload(final IUpload upload, final byte[] contents, final String contentType) {
final UploadEntity uploadEntity = this.mapperService.toEntity(upload);
this.uploadDao.save(uploadEntity);
final StoredUploadMetadata metadata = new StoredUploadMetadata();
metadata.setValue("u.id", String.valueOf(uploadEntity.getId()));
final IStoredUpload<?> storedUpload = this.UploadStoreManager.putUpload(contents, metadata);
// ContentLength populated during call to putUpload()
uploadEntity.setSize(storedUpload.getMetadata().getContentLength());
final UploadStoreEntity uploadStoreEntity = this.uploadStoreDao.save(new UploadStoreEntity());
uploadEntity.setUploadStoreId(uploadStoreEntity.getId());
final UploadEntity updatedUploadEntity = this.uploadDao.saveAndFlush(uploadEntity);
return this.mapperService.toDTO(updatedUploadEntity);
}

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]

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;
}
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 : ]
