Spring Boot JPA #Query and mapping problem" Unable to build Hibernate SessionFactory"

I have problem with my web application. I need to display in Listthings from 4 tables.
My main table is "umowienia" "appointment" and it have connection one to many with klienci AS "clients", pracownik AS "employee", usługi AS "services", and stanowiska AS "positions"
I want to connect this tables to display it on List on one of the application pages.
When I connect tables program say to me error like this
Error creating bean with name 'realizacjeRepository' defined in figura.zaklad_fryzjerski_v3.repository.RealizacjeRepository defined in #EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not determine type for: java.util.List, at table: klienci, for columns: [org.hibernate.mapping.Column(umowienia)]

If you need more code just write and I'll add it

You are using field access strategy (determined by #Id annotation). Put any JPA related annotation right above each field instead of getter property like this in your kilenci entity
#OneToMany(targetEntity = Umowienia.class, mappedBy = "klienci",cascade=CascadeType.ALL, fetch = FetchType.LAZY)
public List<Umowienia> umowienias;

Composite Key - Hibernate

I have a table GROCERY which has following structure:
CREATE TABLE grocery
(
gro_id NUMBER,
gro_name VARCHAR(32),
gro_dep_name VARCHAR(32),
gro_price NUMBER(16, 2),
gro_max_discount NUMBER(16, 2),
CONSTRAINT gro_pk PRIMARY KEY (gro_id, gro_dep_name)
)
My problem is that, when I am trying to fetch the data from the table (saved in my oracle data base) , I am getting the following error :
org.hibernate.id.IdentifierGenerationException: null id generated

I have generated following entity classes according to the structure of the table :

Please help me out, I am not able to figure out what is wrong in it.
Following is my service to take the data from database, which has GroceryRepository which extends CrudRepository :
#Service
public class GroceryService {
#Autowired
GroceryRepository groceryRepository;
public List<Grocery> getAllGrocery()
{
List<Grocery> groceries = new ArrayList<>();
groceryRepository.findAll().forEach(groceries::add);
return groceries;
}
public void addGrocery(Grocery grocery)
{
groceryRepository.save(grocery);
}
}

Missed #EmbeddedId annotation in Grocery.java. Update your code as below.
#EmbeddedId
private GroceryId id;

Just use #EmbeddedId.There must be only one EmbeddedId annotation and no Id annotation when the EmbeddedId annotation is used.
#EmbeddedId
private GroceryId id;

well, I'm new to spring. When I try to compile these codes, I'm getting the below-mentioned error. so please help me to sort out this problem. Thanks in advance!

It's not enough details in your question to help you resolve it right away, however you should
Google for LazyInitializationException - it's a common newbie problem. And it's a runtime exception, not compile time
Read the docs of the framework you're using (pure Spring or Spring Boot, JPA) how to open a transaction/session
Read about lazily initialized collections in JPA/Hibernate
Make sure you either open session/transaction in view (usually anti-pattern) or put a #Transactional annotation on your code.
Looking at your code, you're trying to serialize JPA entity rihght away to JSON so open-session-in-view will work for you, however you need to be VERY CAREFUL. This pattern is useful only in very simple applications.

LazyInitializationException is occurred while you getting #ManyToMany and #OneToMany objects
Hibernate is LAZY loading in case of(#ManyToMany and #OneToMany)
So while getting #ManyToMany or #OneToMany relation objects you should first iterate in DAO layer , and get the data other wise it shows LazyInitializationException

The image is format BASE64, but throws me the following error:
javax.servlet.ServletException: Exception [EclipseLink-6065] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.QueryException
Exception Description: Cannot add the object [activo.entities.Imagenes[ idImagenes=0 ]], of class [class activo.entities.Imagenes], to container [class activo.entities.Imagenes].
Internal Exception: java.lang.ClassCastException: activo.entities.Imagenes cannot be cast to java.util.Collection
as it should send the form? Thanks

I just needed to remove the brackets , remove the GlassFish default has netbeans , delete all records and install a new one.
So I stick to insert the image into base64 to database

how to set a pojo as a moxy?

I have this file:
#XmlRootElement(name="Projects")
public class Projects extends ResponseWrapper {
private ArrayList<Project> project;
#XmlElement(name="Project")
public ArrayList<Project> getProject() {
return project;
}
public void setProject(List<Project> list) {
this.project = (ArrayList<Project>)list;
}
}
Project has an #XMLInverseReference
System.out.println(JAXBContext.newInstance(Projects.class).getClass()); //error
Exception Description: The method [setProject] or [getProject] is not defined in the object [com.tps.www.data.Projects].
While printing out Project.class:

Note: I'm the EclipseLink JAXB (MOXy) lead and a member of the JAXB (JSR-22) expert group.
I have not been able to reproduce the issue you are seeing. Could you help provide more information so that I can reproduce the problem? Here is what I have tried:
Removed JPA & Hibernate annotations from Project class to get it to compile.
Created empty ResponseWrapper class for Project and Projects to extend.
Created classes for each class referenced by Project.
When a property is marked with #XmlInverseReference added the project property on the corresponding type:
public class Contract {
private Project project;
public Project getProject() {
return project;
}
public void setProject(Project project) {
this.project = project;
}
}
Ran the following demo code:
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Projects.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum19953731/input.xml");
Projects projects = (Projects) unmarshaller.unmarshal(xml);
}
}
