if got a language table and a system table with a many-to-many relationship:
Language:
#JsonAutoDetect
#Entity
#Table(name = "language")
public class Language implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "language_id", nullable = false)
private int languageId;
#Column(name = "language_name", nullable = false)
private String languageName;
#Column(name = "language_isocode", nullable = false)
private String languageIsoCode;
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "system_language", joinColumns = {#JoinColumn(name = "language_id", updatable = false)},
inverseJoinColumns = {
#JoinColumn(name = "system_id", updatable = false)}, uniqueConstraints = {
#UniqueConstraint(columnNames = {
"language_id",
"system_id"
})})
private List<System> systems;
public Language() {
}
// GETTER & SETTERS
// ....
}
System
#JsonAutoDetect
#Entity
#Table(name = "system")
public class System implements Serializable {
#Id
#Column(name = "system_id", nullable = false)
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer systemId;
#Column(name = "system_name", nullable = false, unique = true)
private String systemName;
#OneToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "university_id", nullable = false)
private University university;
#JoinColumn(name = "calender_id", nullable = false)
#OneToOne(fetch = FetchType.EAGER)
private Calendar calender;
#OneToMany(mappedBy = "system")
#LazyCollection(LazyCollectionOption.FALSE)
private List<SystemUserRole> systemUserRoleList;
#OneToMany(mappedBy = "system")
#LazyCollection(LazyCollectionOption.FALSE)
private List<Role> roleList;
#OneToOne(mappedBy = "system")
#LazyCollection(LazyCollectionOption.FALSE)
private CsmUserEntity csmUserEntity;
#ManyToMany(mappedBy = "systems")
#LazyCollection(LazyCollectionOption.FALSE)
private List<Language> languages;
public System() {
}
// GETTER & SETTERS
// ....
}
When im writing a first dataset (systemId=1, language_id=20) into the table, everything works fine. But when i try to write a second dataset with the same language_id but with other system_id (systemId=2, language_id=20), then the existing dataset gets updated. But i want to have a new dataset instead. What can i do?
Thanks in advance!

During Purchase Insert, everything works fine. However, if I update the Purchase record in the database and add new PurchaseItem entry, I encounter the issue below:
org.springframework.dao.DataIntegrityViolationException: not-null property references a null or transient value : com.be.entity.PurchaseItem.product; nested
I have debugged my application and I see that there is a Product instance inside all of the PurchaseItem. When I commented out the PurchaseProductBatch inside PurchaseItem, everything works fine so I conclude that it is the causing the issue. However, I don't understand how and why JPA seems to create phantom PurchaseItem Records with no value.
Also, if I only update an existing PurchaseItem entry in Purchase, I don't encounter any issues.
Anyone have any ideas on how I could do postmapping for the Many-to-Many relationship? Getting the data works, but this is what I'm having trouble with
I tried using the "guide" but unfortunately I don't understand it very well yet

I am seeing this below error.
ORA-01407: cannot update ("PAYMENTS"."MATCH_RESULT"."ORDER_ID") to NULL
This endpoing is not exposed to user. There is a batch job which invokes this endpoint.
This code has been there for atleast a year and this is the first time i am seeing this.
This happened only once and for only one call. I am seeing both the logs printed. I am puzzled why I am seeing above error complaining about NULL order id. From the logs, we can confirm that the order id is definitely not null.
Any idea why this is happening? What can be done to fix this?
Two foreign keys act as primary key in entity for OneToOne, I'm getting error "Provided id of the wrong type for class ....."
When I tried to POST data, It's getting inserted correctly but GET is not working.
If I change OneToOne to OneToMany it is working for POST & GET both.
Request:

Here is the code.
I'm an entity Story:

#Table(name = "story", schema = "")

public class Story implements Serializable {
private static final long serialVersionUID = 1L;

#Column(name = "sID", unique = true, nullable = false)
private Long sID;
#Column(name = "vnName", nullable = false)

#ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
#JoinTable(name = "_scategory",
joinColumns = {#JoinColumn(name = "sID", nullable = false)},
inverseJoinColumns = {#JoinColumn(name = "cID", nullable = false)})
private List<Category> categoryList;
}
And Entity Category:
#Entity
#Table(name = "category", schema = "", uniqueConstraints = {#UniqueConstraint(columnNames = {"cMetatitle"}),
#UniqueConstraint(columnNames = {"cName"})})
#Data
public class Category implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "cID", unique = true, nullable = false)
private Integer cID;
#Column(name = "cName", unique = true, nullable = false, length = 150)
private String cName;
#ManyToMany(mappedBy = "categoryList")
private List<Story> storyList;
}
But when I grab the Story in RestController, I get the following error message:

to resolve exception
[org.springframework.http.converter.HttpMessageNotWritableException]
java.lang.IllegalStateException: Cannot call sendError() after the

Can anybody show me how to fix it? Thank you!
