Unable to fetch child entity using #naturalId

Unable to fetch child entity using #naturalId - spring-boot

I am trying to fetch the parent entity using #NaturalId column, it is giving me the below exception.
java.lang.IllegalArgumentException: Can not set java.lang.String field com.example.demo.entities.Payment.referenceNo to java.lang.String
at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:167) ~[na:1.8.0_231]

at java.lang.reflect.Field.get(Field.java:393) ~[na:1.8.0_231]
The Entities are defined as
#Entity
public class Payment {
#Id
#GeneratedValue(generator = "uuid")
#GenericGenerator(name = "uuid", strategy = "uuid2")
public String id;
#NaturalId
public String referenceNo;
#Entity
public class Sender {
#Id
#GeneratedValue(generator = "uuid")
#GenericGenerator(name = "uuid", strategy = "uuid2")
private String id;
#Column
private String senderName;
#Column
private String senderMobile;
#OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
#JoinColumn(name = "PAYMENT_ID", referencedColumnName = "referenceNo")
#JsonBackReference
public Payment payment;
In service class I am using repo.findByReferenceNo(refNo);
And if I use EnitityManager Session session = entityManager.unwrap(Session.class);
Payment b = session.bySimpleNaturalId(Payment.class).load(refNo);
I am getting below exception
org.hibernate.property.access.spi.PropertyAccessException: Error accessing field [public java.lang.String com.example.demo.entities.Payment.referenceNo] by reflection for persistent property [com.example.demo.entities.Payment#referenceNo] : 442056d5-2c2e-43be-91a9-f827c612e6d7

Extend Entity to add functionality Spring JPA with Kotlin

Let's say i have a simple entity:
#Entity
open class NumberEntity(
#Id
#GeneratedValue(generator = "UUID")
#Type(type = "uuid-char")
#Column(name = "id")
open var id: UUID,
open var anInt: Int
)
And now i want to extend the entity class to add some functionality like this:
class Number(id: UUID, anInt: Int) : NumberEntity(id, anInt) {
constructor(entity: NumberEntity) : this(entity.id, entity.anInt)
fun increment() = anInt++
}
So in the service i can use the functional programming like this:
#Service
class NumberService {
#Autowired
lateinit var numberRepository
fun incrementById(id: UUID) =
numberRepository.findById(id)
.orElseThrow( throw ResponseStatusException(HttpStatus.NOT_FOUND))
.run { Number(this) }
.increment()
.let { numberRepository.save(it) }
}
but i get an error when trying to save the Number (The stack trace is from my actual code not from the sampe above):

What can i do to fix it? Is The aproach im taking with extending the Entity to add methods right in the first place?

java.lang.IllegalArgumentException: Parameter value [232cb466-6af9-4d7e-85ec-cc72c310d7fd] did not match expected type [java.util.UUID

I'm using Spring boot, RSQL
Below is my repo
#Repository
public interface SomeRepository extends JpaRepository<NonConfig, UUID>, JpaSpecificationExecutor<NonConfig>{
}
below is my entity
#Entity
#Table(name = "NON_CONFIG")
public class NonConfig {
#Id
#Type(type = "uuid-char")
#GeneratedValue(generator = "UUID")
#GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
#Column(name = "NON_CONFIG_ID", updatable = false, nullable = false)
private UUID id;
private String frameWork;
private String versionId;
i do have setters and getters for id
}
#Service
public class NonConfigServiceImpl implements NonConfigService {
#Autowired
SomeRepository someDao;
#Override
public Page<NonConfig> getNonConfigDetails(Integer pageNo, Integer pageSize, String search, String sortBy, String sortingOrder) {
Node rootNode = new RSQLParser().parse(search);
Specification<NonConfig> spec2 = rootNode.accept(new RapRsqlVisitor<NonConfig>());
Pageable pageable = null;
//Pageable pageable = PageRequest.of(pageNo, pageSize, Sort.by(sortBy));
if(sortingOrder.equalsIgnoreCase("ASC")) {
pageable = PageRequest.of(pageNo, pageSize, Sort.Direction.ASC, sortBy);
}else {
pageable = PageRequest.of(pageNo, pageSize, Sort.Direction.DESC, sortBy);
}
Page<ModelConfig> pagedResult = configDao.findAll(spec2, pageable);
}
}
below is my controller code snippet
#Override
#GetMapping()
public Page<NonConfig> NonConfigDetails(
#RequestParam(defaultValue = "0") Integer pageNo,
#RequestParam(defaultValue = "25") Integer pageSize, String search,
#RequestParam(defaultValue = "lastUpdatedDate") String sortBy,
#RequestParam(defaultValue = "ASC") String sortOrder) {
return configService.getNonConfigDetails(pageNo, pageSize, search, sortBy, sortOrder);
}
http://localhost:1010/XXXXXXX/YYYYYYYYYY?search=id==232cb466-6af9-4d7e-85ec-cc72c310d7fd
when i hit this URL, i ended up with below error.
after debugging i identified this below line of code is throwing exception
Page<ModelConfig> pagedResult = configDao.findAll(spec2, pageable);
So, Based on the logs, i understood that UUID is treated as string and henceforth the exception java.lang.IllegalArgumentException: Parameter value [232cb466-6af9-4d7e-85ec-cc72c310d7fd] did not match expected type [java.util.UUID
how can i correct this.? and
below are the complete logs

You have a String search which is a String. You need an UUID and looking at this specific class, you have fromString(String name) which is documented as Creates a UUID from the string standard representation as described in the toString() method.
I think you have all the steps to figure out what you need to do based on this answer =)

After saving the identifier must not be null error

I am trying to build a POC for one of our projects, and have been experimenting with spring data jpa module. I'm using h2 database, and the database has only one table. I have an entity object that is mapped to the table. I have a test controller that gets the json object. I created an entity object out of it, and the entity object is passed on to the repository. I have a service that is using the save( ) method to insert a new record in to the table. I see that proper id is generated, but the operation fails with an exception - "after saving the identifier must not be null".
I tried all the different combinations for the id here, but I guess the identifier the code is referring to is probably another identifier I am not aware of. There is a static class AbsentIdentifierAccessor in BasicPersistentEntity (spring class) that gets called for the identifier.
private static class AbsentIdentifierAccessor extends TargetAwareIdentifierAccessor {
public AbsentIdentifierAccessor(Object target) {
super(target);
}
/*
* (non-Javadoc)
* #see org.springframework.data.mapping.IdentifierAccessor#getIdentifier()
*/
#Override
#Nullable
public Object getIdentifier() {
return null;
}
}
Did anyone have a similar problem with using the repository methods? Any insights here will be helpful here.
#Repository
public interface TimeSheetRepository extends JpaRepository<Timesheet, Long> {
}
#Entity
#Table(name = "Timesheet")
public class Timesheet implements Serializable {
private static final long serialVersionUID = 7157684222538550301L;
#Id
#GeneratedValue
private Long timesheet_entry_id;
#Column(length = 100,nullable = false)
private String client;
#Column(length = 100,nullable = false)
private String project;
public Long getTimesheet_entry_id() {
return timesheet_entry_id;
}
public void setTimesheet_entry_id(Long timesheet_entry_id) {
this.timesheet_entry_id = timesheet_entry_id;
}
}

Use generation Type strategy and let Hibernate handle primary key generation.
If you want auto increment primary key then use below.
#GeneratedValue(strategy=GenerationType.AUTO)

Save Child entity with parent entity: java.sql.SQLException: Field 'post_id' doesn't have a default value

I have Post enetity as parent entity where I have one to many relationship with comment entity
#Data
#Entity
public class Post implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
#OneToMany(mappedBy = "post", cascade = CascadeType.ALL)
private Set<Comment> comments;
}
and here is my child entity:
#Data
#Entity
public class Comment implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String comment;
#ManyToOne
#MapsId("id")
#JoinColumn(name = "post_id")
private Post post;
}
but when I try to save child entities with parent entity, parent id is inserting null while I have Cascade type = all.
Post post = new Post();
post.setName("Post 1");
Comment comment = new Comment();
comment.setComment("comment 1");
Set<Comment> commentList = new HashSet<>();
commentList.add(comment);
post.setComments(commentList);
Post newPost = postRepository.save(post);
return new ResponseEntity<>(newPost, HttpStatus.OK);
am i missing something to insert all child records with parent.
here is error:

First of all you don't need to set #GeneratedValue for Id if yu use #MapsId. Secondly, you also need to set the post object of comment. Thirdly, you need to use #JsonManagedReference and #JsonBackReference if you want to serialize using jackson in order to avoid infinite loop or #JsonIgnore to avoid the field which can create infinite loop, which means your code will look like below:
#Data
#Entity
public class Post implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
// #JsonManagedReference
#OneToMany(mappedBy = "post", cascade = CascadeType.ALL)
private Set<Comment> comments;
}
and
#Data
#Entity
public class Comment implements Serializable {
#Id
private Long id;
private String comment;
// #JsonBackReference
#JsonIgnore
#ManyToOne
#MapsId
#JoinColumn(name = "post_id") // exact foreign key name on comments table
private Post post;
}
and your save method from the controller / service like below:
Post post = new Post();
post.setName("Post 1");
Comment comment = new Comment();
comment.setComment("comment 1");
comment.setPost(post);
Set<Comment> commentList = new HashSet<>();
commentList.add(comment);
post.setComments(commentList);
Post newPost = postRepository.save(post);
UPDATE
The problem might reside in your database. You need to set AUTO_INCREMENT to your primary key field. A shortcut is available for that. Always use SERIAL to your id while creating table as it is the shortcut to BIGINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY. Alter both the tables' id with SERIAL

A post may or may not have the comments so you make your field nullable like below.
#JoinColumn(name = "post_id", nullable = true)

Hibernate Field with Timestamp doesn't work. java.sql.SQLException: Field 'timestamp' doesn't have a default value

I have created a database and can fill it with Hibernate. There are no errors.
Now I've set Hibernate to automatically create tables if they do not exist. The Timestamp has a value when i try to save it.
The only difference I could see in the MySQL Workbench:
Original: DATETIME (6)
Hibernate DATETIME
Can this cause the error? According to MySQL Workbench, there is no error here.
With this option I get the following error:
