How to update an item in one to many relationship - java

I am trying to update a one to many relationship but getting a
insert into sw_standard_standard (sw_standard_id, standard_id) values
(?, ?) [23505-192]]; nested exception is
org.hibernate.exception.ConstraintViolationException
Here is my code:
SwStandard
#Entity
public class SwStandard implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
#OneToOne
private DeviceType deviceType;
#ElementCollection
#OneToMany
private List<Image> standard;
#ElementCollection
#OneToMany
private List<Image> limited;
#ElementCollection
#OneToMany
private List<Image> exception;
public SwStandard() {}
public SwStandard(DeviceType deviceType, List<Image> standard, List<Image> limited, List<Image> exception) {
this.deviceType = deviceType;
this.standard = standard;
this.limited = limited;
this.exception = exception;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public DeviceType getDeviceType() {
return deviceType;
}
public void setDeviceType(DeviceType deviceType) {
this.deviceType = deviceType;
}
public List<Image> getStandard() {
return standard;
}
public void setStandard(List<Image> standard) {
this.standard = standard;
}
public List<Image> getLimited() {
return limited;
}
public void setLimited(List<Image> limited) {
this.limited = limited;
}
public List<Image> getException() {
return exception;
}
public void setException(List<Image> exception) {
this.exception = exception;
}
}
Image
#Entity
public class Image implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
private String name;
public Image() {}
public Image(String name) {
this.name = name;
}
public Image(Long id, String name) {
this.id = id;
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Update code:
#RequestMapping(value = "/swstandard/update", method = RequestMethod.POST)
public SwStandard updateSwStandard(#RequestBody SwStandard request) {
return swService.save(request);
}
SwService:
#Autowired
private SwStandardRepository swService;
SwStandardRepository:
public interface SwStandardRepository extends CrudRepository<SwStandard, Long> {
SwStandard findByDeviceTypeId(Long id);
}
First I save a SwStandard with 1 standard item. Then I save want to replace the standard item with something else. When I do this it returns the error above.
Edit
Alan Hay help partially helped.
Now I cannot save the same image across a SwStandard for example here is a SwStandard I'll save:
{
"id": 1,
"deviceType": { "id": 1 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
and here is another SwStandard I'll save which will fail with the error above:
{
"id": 2,
"deviceType": { "id": 2 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
As you can see both SwStandards have the same standard item.
Here is the log output:

Hibernate JPA - Wrongly generated insert statement

Hibernate is generating wrong insert statement - wrong column binding - for the following entity model with single table inheritance and composite primary key using #IdClass.
Wondering if this is a Hibernate bug.
Stack: Spring Boot 2.7 / H2
Superclass base entity - AbstractMemberEvent:
#Entity
#Table(name = "MEMBER_EVENTS")
#Getter
#FieldDefaults(level = AccessLevel.PRIVATE)
#Inheritance(strategy = InheritanceType.SINGLE_TABLE)
#DiscriminatorColumn(name = "EVENT_TYPE")
#NoArgsConstructor
#IdClass(MemberEventId.class)
public abstract class AbstractMemberEvent {
#Id
#Column(name = "USID")
String usid;
#Id
#Column(name = "UPDATED")
Long eventTime;
#Id
#Column(name = "EVENT_TYPE", insertable = false, updatable = false )
String eventType;
Subclass entity - NewMemberJoined
#Entity
#Getter
#Setter
#FieldDefaults(level = AccessLevel.PRIVATE)
#DiscriminatorValue("NEWMEMBERJOINED")
#NoArgsConstructor
public class NewMemberJoined extends AbstractMemberEvent{
#Column(name="PAYLOAD")
NewMemberJoinedInfo newMemberJoinedInfo;
The IdClass
#Getter
#FieldDefaults(level = AccessLevel.PRIVATE)
#NoArgsConstructor
#EqualsAndHashCode
public class MemberEventId implements Serializable {
String usid;
Long eventTime;
String eventType;
}
From the logs I see that the wrong values are bound to the parameters
Hibernate:
create table member_events (
event_type varchar(31) not null,
updated bigint not null,
usid varchar(255) not null,
payload varchar(255),
primary key (updated, event_type, usid)
)
...
Hibernate:
insert
into
member_events
(payload, event_type, updated, usid)
values
(?, ?, ?, ?)

Instead of update query , calling insert query in spring jpa

I am trying to update multiple table in spring jpa.
Consumer table update is happening perfectl but provider table is not able to update. Instead of it , its trying for insert which causes violation of primary key which is expected because it is trying for insert instead of update.
Although my code flow for both the table is same but there is issue only with producer.
This is my Consumer entity
import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
#Data
#Entity
#Table(name = "consumer_table")
#IdClass(ConsumerId.class)
public class Consumer implements Serializable {
#Id
#Column(name = "consumer_cmdb")
private String consumerCMDB;
#Id
#Column(name = "api_name")
private String apiName;
#Column(name = "consumer_app_vp")
private String consumerAppVp;
#Column(name = "consumer_app_director")
private String consumerAppDirector;
#Column(name = "consumer_app_manager")
private String consumerAppManager;
#Column(name = "consumer_tps")
private String consumerTps;
#Column(name = "consumer_hosted_on")
private String consumerHost;
#Column(name = "consumer_system_type")
private String consumerSystemType;
#Column(name = "carbon_namespace_ownership")
private String consumerCarbonNamespaceOwnership;
#Column(name = "hosted_vm_ownership")
private String consumerHostedVmOwnership;
#Column(name = "consumer_status")
private String consumerStatus;
#Column(name = "comments")
private String ConsumerComments;
#Column(name = "consumer_auth_type")
private String ConsumerAuthType;
}
This is my Consumer repository
import java.util.List;
#Repository
public interface ConsumerRepository extends JpaRepository<Consumer, ConsumerId> {
List<Consumer> findByConsumerCMDB(String CMDB);
#Query(nativeQuery = true,value = "select count(*) from consumer_table where api_name IS NOT NULL AND consumer_cmdb=:cmdbId")
Integer getTotalApisOwned(#Param("cmdbId") String cmdbId);
List<Consumer> findByApiName(String apiName);
Consumer findByApiNameAndConsumerCMDB(String apiName,String consumerCMDB);
}
This is my Provider entity
import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
#Data
#Entity
#Table(name = "provider_table")
#IdClass(Provider.class)
public class Provider implements Serializable {
#Id
#Column(name = "api_name")

#Id
#Column(name = "provider_cmdb")
private String providerCMDB;
#Column(name = "provider_app_vp")
private String providerAppVp;
#Column(name = "provider_app_director")
private String providerAppDirector;
#Column(name = "upstream_service_hosted_on")

#Column(name = "hosted_vm_ownership")
private String providerHostedVmOwnership;
#Column(name = "provider_status")
private String providerStatus;
#Column(name = "comments")
private String providerComments;
}
This is my Provider Repository
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository

As the service layer isn't given based on the question i would like to answer,considering providerRepository object is present
Provider provider=providerRepository.findByUpstreamServiceUrl("xyz"); //Assuming using this method
provider.setXYZ(..);///set the values needed to be updated
providerRepository.save(provider); // As JPA works on state of an object this would update the object instead in inserting in DB
As ID of Object is present in DB instead of inserting new it will merge by calling save method
Refer:How do I update an entity using spring-data-jpa?

#Modifying annotation is used to enhance the #Query annotation so that we can execute not only SELECT queries, also insert, update, delete, and even DDL queries.
For more detail go through this link.
You can also use #Modifying and #Query to write your custom JPA query
to update the Provider table.
#Modifying
#Query("your custom JPQL update query")
What you can also do is get the previous provider entity/data you want to update and do the changes in the same data and again save it.

I got the issue.Actually in Provider class , I was annotating with wrong class. I have made the changes and now It's working fine :)
Here is the latest Provider entity class
#Data
#Entity
#Table(name = "provider_table")
#IdClass(ProviderId.class)

#Column(name = "api_name")

Error of "Duplicate entry '14' for key 'dishes.PRIMARY'" When saving a value in DB via Json file

I have a problem saving a row in the "Orders" table. Each order includes a list of dishes.
When I saved through the code everything was fine. But when I send a JSON file, I see that Spring sends an update command to the DISH table. And I do not understand why, how can he be made not to update the value obtained?
this is the orders class:
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Entity
#Table(name="Orders")
public class Orders {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int orderId;
#Column(name="customer_name")
private String customerName;
#ElementCollection
#ManyToMany(mappedBy ="Orders",cascade = CascadeType.MERGE)
#JoinColumn(name = "id")
private List<Dish> dish;
#Column(name="order_date")
private Date orderDate;
#Enumerated(value = EnumType.ORDINAL)
#Column(name = "status_id")
private Status status;
#Enumerated(value = EnumType.ORDINAL)
#Column(name = "table_id")
private RTable table;
#ManyToOne
#JoinColumn(name = "waiter_id")
private Waiter waiter;
#Column(name="total_price")
private double totalPrice;
The Dish class:
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
#Entity
#Table(name="dishes")
public class Dish{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name;
#Column(name="preperation_Time_By_Minutes")
private double preperationTimeByMinutes;
private double price;
}
part from the trace: (including the unwanted update query)

HttpMessageNotWritableException: Could not write JSON: Could not initialize proxy AFTER adding data into DB

Here's my question. I am unable to write the JSON after I send a POST request from POSTMAN to create/add a row into my SQL database. I need the server to send back a response of the added entry in order to retrieve the ID that SQL generates.
I face this issue when the new Case entry is a child of two entities(User and Application) and a grandchild of one entity(Owner).
*User(Owner)
|\
| *Application
|/
*Case
I'm new and currently using the Spring Boot JPA package.
I'm aware that many have asked questions related to the error above. There is none regarding my case to my knowledge. All of them refer to fixes over a HTTP GET method. If you found some please guide me to them. Or please help to answer my query. Any help is appreciated!

There are as many problems with your code as i really don't know how to help to solve it.
but as a quick fix try to create a new entity class for user object.

Solved it with this workaround.
Since fooService.save(foo); also updates the foo object with the ID, I can simply return foo.getId() to achieve what I want without sending another find method.
i.e. Case Service
public Integer updateCase(Case aCase) {
caseRepository.save(aCase);
return aCase.getId();
}

Hibernate and postgresql. Errors while exporting schema

I'm getting around 10 errors when I start my Spring Boot app using Hibernate and postgresql. How can I fix them? WHat's the problem?
Here are my entities:
Customer.java
#Entity

public class Customer {

user is a reserved keyword in postgresql. I would suggest renaming your entity class to some other name, or just use hibernate annotations #Table to specify postgresql friendly table name, like this:
#Entity
#Table(name = "library_user")
public class User {...}

User is reserved word in most if not all of the databases. Use some other name for this purpose.
Words
