I have following entities:
public class MyEntity extends AuditableEntity {
#Column
private String name;
}
AuditableEntity class:
public class AuditableEntity {
#Id
#GenericGenerator(name = "uuid-gen", strategy = "uuid2")
#GeneratedValue(generator = "uuid-gen", strategy = GenerationType.IDENTITY)
private String id;
#CreatedBy
#JsonIgnore
#Embedded
#AttributeOverrides({
#AttributeOverride(name = "user", column = #Column(name = "created_by_id")),
#AttributeOverride(name = "clientId", column = #Column(name = "created_by_client_id"))
})
private AuditorDetails createdBy;
#LastModifiedBy
#JsonIgnore
#Embedded
#AttributeOverrides({
#AttributeOverride(name = "user", column = #Column(name = "last_modified_by_id")),
#AttributeOverride(name = "clientId", column = #Column(name = "last_modified_by_client_id"))
})
private AuditorDetails lastModifiedBy;
}
And my AuditorDetails class:
#Embeddable
public class AuditorDetails {
#Column(name = "auditor_client_id")
private String clientId;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn
private User user;
}
Also, I have AuditorAware that returns AuditorDetails object. When I try to run this, I have following exception:
org.hibernate.MappingException: Repeated column in mapping for entity:
com.aaa.MyEntity column: user_id (should be mapped with insert="false"
update="false")
But I can't make this column(s) not updatable and not insertable. The main goal is to have in MyEntity 4 columns - created_by_id, created_by_client_id, last_modified_by_id, last_modified_by_client_id that will contain all data about row modification and creation. How to fix this exception?
I have fixed this issue just adding annotations AssociationOverrides:
#CreatedBy
#JsonIgnore
#Embedded
#AssociationOverrides({
#AssociationOverride(name = "user", joinColumns = #JoinColumn(name = "created_by_id"))
})
#AttributeOverrides({
#AttributeOverride(name = "user", column = #Column(name = "created_by_id")),
#AttributeOverride(name = "clientId", column = #Column(name = "created_by_client_id"))
})
private AuditorDetails createdBy;
#LastModifiedBy
#JsonIgnore
#Embedded
#AssociationOverrides({
#AssociationOverride(name = "user", joinColumns = #JoinColumn(name = "last_modified_by_id"))
})
#AttributeOverrides({
#AttributeOverride(name = "user", column = #Column(name = "last_modified_by_id")),
#AttributeOverride(name = "clientId", column = #Column(name = "last_modified_by_client_id"))
})
private AuditorDetails lastModifiedBy;

I was able to get this ManyToOne relationship with a composite pk working for GET requests but I am having issues with saving new entries.
I have a parent entity with an embedded id.
#Embeddable
public class AnnualServiceHistoryPK implements Serializable {
#Column(name = "year", columnDefinition = "int(4)")
Integer year;
#Column(name = "month", columnDefinition = "char(3)")
String month;
#Column(name = "route", columnDefinition = "varchar(32)")
String route;
This is placed in the parent entity:
#Entity(name = "AnnualServiceHistory")
#Table(name = "annual_service_history")
public class AnnualServiceHistory extends Auditable<String> implements Serializable
{
#EmbeddedId
AnnualServiceHistoryPK annualServiceHistoryPK;
... other variables
#OneToMany(mappedBy = "annualServiceHistory", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
List<AnnualServiceHistoryNonMachine> annualServiceHistoryNonMachineList;
I have the child entity which maps the embedded id from the parent and adds and additional local PK.
public class AnnualServiceHistoryNonMachine extends Auditable<String> implements Serializable {
#Id
#MapsId
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "year", referencedColumnName = "year")
#JoinColumn(name = "month", referencedColumnName = "month")
#JoinColumn(name = "route", referencedColumnName = "route")
private AnnualServiceHistory annualServiceHistory;
#Id
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "toy_inventory", referencedColumnName = "id")
ToyInventory toyInventory;
... other variables
My issue is, when I save the parent with a list of children for some reason during the cascading processes, when it is generating the child key it is only creating the key from the MapsId parts and complains that the toyInventory key is null. I'm not sure why it loses this ID because prior to performing the repository save the child class has the toyInventory key in the object.
This is the error I am receiving:
"java.sql.SQLIntegrityConstraintViolationException: Column 'toy_inventory' cannot be null"
Solution found. - https://medium.com/#bhagyajayashani/composite-key-handling-using-idclass-annotation-in-spring-boot-java-26f40bbd38a2
Changed from using #embeddedId to using #classId. Then created a separate join object, and created join based off individual variables not the embeddedId.
#Embeddable

Integer year;

I'm trying to set simple entity with NamedEntityGraph on it. Unfortunately it won't work. Could you have any ideas how to fix it?
ServiceType entity has #ElementCollection of with Set of String which are simply ids of PictureModel associated with entity. On run I got:
Caused by: javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name [backgroundPicIds] on this ManagedType [pl.mihome.djcost.model.ServiceType]

public class ServiceType {

}
You simply do not have an attribute with the name backgroundPicIds in the entity ServiceType.
Try to correct your graph in this way:
#NamedEntityGraph(
name = "serviceType.with.backgroundPicIds",
attributeNodes = #NamedAttributeNode("backgroundPictureId")
)

}
In your TAbleAa you should have your OneToMany mapping as follows:
#OneToMany(mappedBy = "pk.tableAa", cascade = CascadeType.ALL)
private List<TableBb> tableBbList;
You reference through the embeddable which name is pk.
I think your problem in this entity
#Entity
#Table(name = "TABLE_BB")
public class TableBb {
#EmbeddedId
private TableBbPk pk;
#Column(name = "FIRST_NAME")
private String first_name;
#Column(name = "LAST_NAME")
private String last_name;
// I think the solution is to add the relation #ManyToOne which mapped by in the other side
#ManyToOne // because u refere to this name (tableAa) in #OneToMany(mappedBy = "tableAa"...) in TableAa entity
private TableAa tableAa;
}
I'm starting with hibernate and I having some difficulties to build a easy
relationship of tables
, hibernate throw nested exception is org.hibernate.MappingException: Unable to find column with logical name: USERNAME in org.hibernate.mapping.Table(USER_FILESYSTEM) and its related supertables and secondary tables
I have this model
USER--1---N-->USER_FILE_SYSTEM--1--N-->USER_FS_THUMBS
All column name on DB squema are OK the column username" exists on table USER_FILESYSTEM
and table user
Table Users
#Entity
#Table(name = "USERS")
public class Users implements Serializable {
#Id
#Column(name = "USERNAME", nullable = false, length = 15)
private String username;
#Column(name = "PASSWORD", nullable = false, length = 64)
private String password;
#Column(name = "FIRSTNAME", length = 32)
private String firstname;
#Column(name = "LASTNAME", length = 32)
private String lastname;
#Column(name = "EMAIL", nullable = false, length = 60)
private String email;
#Column(name = "TELEPHONE", length = 50)
private String telephone;
#OneToOne(cascade = CascadeType.ALL)
#JoinTable(name = "USER_ROLE",
joinColumns = {
#JoinColumn(name = "USERNAME_ID", referencedColumnName = "USERNAME")},
inverseJoinColumns = {
#JoinColumn(name = "ROL_ID", referencedColumnName = "ROL")}
)
private Rol role;
#OneToMany(
fetch = FetchType.EAGER, mappedBy = "username"
)
private Set<UserFileSystem> fileSystem;
Table UserFileSystem
#Entity
#Table(name = "USER_FILESYSTEM")
public class UserFileSystem implements Serializable {
#Id
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "USERNAME", nullable = false)
private Users username;
#Id
#Column(name = "SERVICE_ID", nullable = false, length = 10)
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer serviceId;
#Id
#Column(name = "SERVICE_FOLDER", nullable = false, length = 64)
private String serviceFolder;
#Column(name = "PROTOCOL", length = 20)

#Column(name = "PARAMS", length = 512)
private String params;
#OneToMany(

Table UserFileSystemThumbs
#Entity
#Table(name = "USER_FS_THUMBS")
public class UserFileSystemThumbs implements Serializable {
#EmbeddedId
private UserFileSystemThumbsPK userFileSystemThumbsPK;
#Column(name = "SERVICE_URL", nullable = false)
private String serviceUrl;
#Column(name = "CONTENT", nullable = false)
private byte[] content;
#Column(name = "MIME_TYPE", nullable = false)
private String mimeType;
Primary key entity UserFileSystemThumbs
#Embeddable
public class UserFileSystemThumbsPK implements Serializable {
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumns({
#JoinColumn(name = "USERNAME", nullable = false, referencedColumnName = "USERNAME"),
#JoinColumn(name = "SERVICE_ID", nullable = false, referencedColumnName = "SERVICE_ID")
})
private UserFileSystem userFileSystem;
#Column(name = "SERVICE_URL_HASH", nullable = false)
private String serviceUrlHash;
Constructor equals hash....
the problem I think that UserFileSystemThumbsPK USERNAME column do reference to UserFileSystem but in this table the column USERNAME is provided by users.
Solution by OP.
I changed
#Entity
#Table(name = "USER_FILESYSTEM")
public class UserFileSystem implements Serializable {
#Id
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "USERNAME", nullable = false)
private Users username;
#Id
#Column(name = "SERVICE_ID", nullable = false, length = 10)
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer serviceId;
}
for this
#Entity
#Table(name = "USER_FILESYSTEM")
public class UserFileSystem implements Serializable {
#EmbeddedId
private UserFileSystemID userFSID;
}
and I created the object UserFileSystemID with 2 values of PK
It's working like a champ!
