Why my servicelaundry_id didn't insert on the table <Hibernate | Spring Boot>

I've created ManyToMany tables with extra column that's named reqserviceguest_details, then I've tested with filling on my jsp page form to insert the data. When the all data inserted, everything is fine except my servicelaundry_id. It's null and I have no idea why it happened.

How to find all accounts by a tenant_id? I can use native SQL query, but I want use Spring Data JPA API more than.

You can use Spring Data Repository query keywords on your composite key by find all accounts by following code.
#Repository
public interface AccountRepository extends JpaRepository<Account, AccountId> {
List<Account> findAllByTenantId(Integer tenant_id);
}

why i can not convert JSON (GSON) date format to java object from retrofit request body?

I am sending request body to server (backed by JAVA/JERSEY/JACKSON) from Android (Retrofit). I im logging request body through interceptor and it looks like something
{"workId":"456655","workName":"some work","workOrderDate":"Jan 29, 2020 12:00:00 AM"}
On server side My Project object is able to parse every field except "workOrderDate". I tried to change Gson date format of various type using
Gson gson = new GsonBuilder()
.setDateFormat("yyyy-MM-dd")
.create();
but still in JSON the format is unchanged (Jan 29, 2020 12:00:00 AM) and it is not assigning to "workOrderDate"field of Project object on server side.
Object on Servier side-

You should try with DateFormat.FULL. It works fine for me like this
Gson gson = new GsonBuilder().setDateFormat(DateFormat.FULL).create();

#ElementCollection does not getting detached

My goal is to clone entity 'Product' with all its filters.
For example, I have an entity (getters and setters omitted for simplicity):
#Entity
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#ElementCollection()
private List<Filter> filters = new ArrayList<Filter>();
}
And embeddable class:
#Embeddable
public class Filter {
#Column(length = 255, nullable = false)
private String name;
#Column(nullable = false)
private long variant = -1;
}
Now, if I do:
entityManager.detach(product);
product.setId(null);
productService.save(product);
I will get a copy of product entity but with filters from original product. In meanwhile original product will end up with no filters at all..
Thats how filter's table rows looks like:
Before:
product_id; name; variant
217; "f2"; 86
After:
product_id; name; variant
218; "f2"; 86
I tried detach each filter from the list but it gives me error.
How can I make it copy filters with an entity?
Edit: Added full Product and Filter code:

I made a mini project trying to replicate your issue.
It is a String Boot project with H2 database and JPA (Hibernate implementation).
On startup, Hibernate creates 2 tables:
create table product (
id bigint not null,
primary key (id)
)
and
create table product_filters (
product_id bigint not null,
name varchar(255) not null,
variant bigint not null
)
On product with filters creation, both tables get inserted:
insert
into
product
(id)
values
(1)
and
insert
into
product_filters
(product_id, name, variant)
values
(1, "f1", 1)
After:
entityManager.detach(product);
product.setId(null);
productService.save(product);
Hibernate issues:
delete
from
product_filters
where
product_id=1
which is normal, since filters is an ElementCollection therefore it is totally owned by the entity Product. On productService.save(product) Hibernate detects that filters collection is bound to another Product therefore deletes the old bound (from product_filter table) before creating a new one.
The only way to overcome the deletion is to recreate the collection:
List<Filter> filters = new ArrayList<Filter>();
filters.addAll(oldFilters);
product.setFilters(filters);
To sum up, here is the solution:
// To trigger the fetch
List<Filter> filters = new ArrayList<Filter>(product.getFilters());
entityManager.detach(product);
product.setId(null);
product.setFilters(filters);
productService.save(product);

You need to specify a property name, not a property type.
SELECT H.MetadataForHibernate FROM HasBooks as H
need to be corrected to
SELECT H.book FROM HasBooks H
And you need a join to check a book properties
SELECT book
FROM HasBooks H inner join H.book book
where book.title :=title

The query you have written is not valid Hibernate Query Language (HQL), check the documentation for hints, or you can always use a native query to get an Object[] list from the result set, keeping the query you already have.
