My entity:
#Entity
#Table(name = "eh_portal")
public class PortalEntity {
#Id
#Column(name = "id", columnDefinition = "CHAR(36)")
private UUID id; //java.util.UUID;
#Column(name = "name")
private String name;
#Column(name = "url")
private String url;
// -- Constructor for Hibernate --
protected PortalEntity() {
}
// -- Constructor for new entity in service code --
public PortalEntity(final UUID id) {
this.id = id;
}
.... getters and setters ommited
}
Respository is Spring DATA JPA:
public interface PortalRepository extends CrudRepository<PortalEntity, UUID> {
}
MYSQL 5 Database table definition:
CREATE TABLE `eh_portal` (
`id` char(36) NOT NULL COMMENT 'UUID',
`name` varchar(255) NOT NULL,
`url` varchar(255) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `url_UNIQUE` (`url`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
The problem is, Hibernate is returning obviously wrong data - see screenshots below
Mysql workbench:
Actual web page where I get entities thru Spring Data JPA:
You can see that UUIDs are obviously differrent, while other columns are correct.
What is wrong here? (Spring 4, Hibernate 4, Spring DATA JPA, Mysql 5)
Try using #Type(type="uuid-char").
I am using Apache CXF (version 2.5.2) to implement REST services that do add, update, delete, query single and list of records on database tables. I am using OpenJPA (version 2.2.0) in the persistence layer.
As an example, I have a table named Complaint, mapped to an entity class of the same name. The complaint entity is similar to this:
import java.io.Serializable;
import java.sql.Timestamp;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
/**
* The persistent class for the "Complaint" database table.
*
*/
#Entity
#Table(name = "Complaint")
#NamedQueries({
#NamedQuery(name = "cmplById", query = "SELECT c FROM Complaint c WHERE c.id = ?1"),
#NamedQuery(name = "cmplBySearchCriteria", query = "SELECT c FROM Complaint c WHERE c.status = ?1 AND c.category = ?2 AND c.location = ?3 AND "
+ "c.reportDate BETWEEN ?4 AND ?5 ORDER BY c.id DESC")
})
public class Complaint implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String description;
private String location;
private Timestamp reportDate;
private String reportedBy;
private String status;
private String category;
public Complaint() {
}
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "Id", nullable = false)
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
#Column(name = "Description")
public String getDescription() {
return this.description;
}
public void setDescription(String description) {
this.description = description;
}
#Column(name = "Location")
public String getLocation() {
return this.location;
}
public void setLocation(String location) {
this.location = location;
}
#Column(name = "ReportDate", nullable = false)
public Timestamp getReportDate() {
return this.reportDate;
}
public void setReportDate(Timestamp reportDate) {
this.reportDate = reportDate;
}
#Column(name = "ReportedBy", nullable = false)
public String getReportedBy() {
return this.reportedBy;
}
public void setReportedBy(String reportedBy) {
this.reportedBy = reportedBy;
}
#Column(name = "Status", nullable = false)
public String getStatus() {
return this.status;
}
public void setStatus(String status) {
this.status = status;
}
#Column(name = "Category", nullable = false)
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
}
All the services are working fine, except for an issue related to two query operations which return data.
The operations getComplaintById and getAllComplaint currently return the entity(s) with all the fields that have values available in database, but with the id field returning as null. I tried structuring the queries in these methods in three ways - using named queries, using native sql and using the find method on entity manager - all of these give the same result.
Just to test, if I try to set the value of id field based on null checking, it is not allowing me, saying the id field has value which is final.
I found same result running the code against both MySQL and Postgres database. Here is code for one of the query method.
public Complaint getComplaintById(Integer id) {
Complaint cmpl;
//case-1: The NamedQueries as defined in the entity class Complaint --> #NamedQuery(name="cmplById", query="SELECT c FROM Complaint c WHERE c.id = ?1")
//Query query = em.createNamedQuery("cmplById");
//case-2: using NativeQuery
//Query query = em.createNativeQuery("SELECT * FROM COMPLAINT WHERE ID=?1", Complaint.class);
//query.setParameter(1, id);
//cmpl = (Complaint) query.getSingleResult();
//case-3: using find method on entity manager
cmpl = em.find(Complaint.class, id);
System.out.println("id = " + cmpl.getId());//returning null, but get method on all other fields returning their values as expected.
return cmpl;
}
In the log I see that the query statement which OpenJPA is executing includes all other fields but not the id field in the select clause as below.
1720 ramsjpa TRACE ["http-bio-8080"-exec-3] openjpa.jdbc.SQL - executing prepstmnt 14227847 SELECT t0.Category, t0.Description, t0.Location, t0.ReportDate, t0.ReportedBy, t0.Status FROM Complaint t0 WHERE t0.Id = ? [params=?]
I am working with CXF and OpenJPA for the first time, and I may be making a basic mistake, all help appreciated.
Are you possibly calling getComplaintById right after inserting it into your database? If so, then your issue might be related to using GenerationType.IDENTITY for your Id field. With GenerationType.IDENTITY, since the id is not assigned by the database until the row is inserted, the id cannot be obtained in the object until after commit or after a flush call. (Reference: http://en.wikibooks.org/wiki/Java_Persistence/Identity_and_Sequencing#Identity_sequencing)
So I think you'd need to do the following before trying to find your Complaint by Id:
Complaint complaint = new Complaint();
// Fill in your complaint fields...
em.persist(complaint);
em.flush();
em.getTransaction().commit();
I have a column in my DB that is set with Identity(1,1) and I can't get hibernate annotations to work for it. I get errors when I try to create a new record.
In my entity I have the following.
#Entity
#Table(schema="dbo", name="MemberSelectedOptions")
public class MemberSelectedOption extends BampiEntity implements Serializable {
#Embeddable
public static class MSOPK implements Serializable {
private static final long serialVersionUID = 1L;
#Column(name="SourceApplication")
String sourceApplication;
#Column(name="GroupId")
String groupId;
#Column(name="MemberId")
String memberId;
#Column(name="OptionId")
int optionId;
#GeneratedValue(strategy=GenerationType.IDENTITY, generator="native")
#Column(name="SeqNo", unique=true, nullable=false)
BigDecimal seqNo;
//Getters and setters here...
}
private static final long serialVersionUID = 1L;
#EmbeddedId
MSOPK pk = new MSOPK();
#Column(name="OptionStatusCd")
String optionStatusCd;
#Column(name="EffectiveDate")
Date effectiveDate;
#Column(name="TermDate")
Date termDate;
#Column(name="SelectionStatusDate")
Date selectionStatusDate;
#Column(name="SysLstUpdtUserId")
String sysLstUpdtUserId = Globals.WS_USER_ID;;
#Column(name="SysLstTrxDtm")
Date sysLstTrxDtm = new Date();
#OneToMany(mappedBy="option")
List<MemberSelectedVariable> variables =
new ArrayList<MemberSelectedVariable>();
//More Getters and setters here...
}
But when I try to add a new record I get the following error.
Cannot insert explicit value for identity column in table 'MemberSelectedOptions' when IDENTITY_INSERT is set to OFF. I don't want to set IDENTIY_INSERT to ON because I want the identity column in the db to manage the values.
The SQL that is run is the following; where you can clearly see the insert.
insert into dbo.MemberSelectedOptions
(OptionStatusCd,
EffectiveDate,
TermDate,
SelectionStatusDate,
SysLstUpdtUserId,
SysLstTrxDtm,
SourceApplication,
GroupId,
MemberId,
OptionId,
SeqNo)
values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
What am I missing?
When you use #Embeddable or #EmbeddedId, the primary key values are supposed to be provided by the application (i.e. made up of non generated values). Your #GeneratedValue annotation is just ignored.
this combination works great for me:
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
Here is the example to do it
#Id
#Column(name = "col_id")
#GeneratedValue(strategy = GenerationType.AUTO)
private Long colId;
Possible you need to mark your field with #id and not specify generator property.
As showed in Hibernate Annotation - 2.2.3.1. Generating the identifier property, the next example uses the identity generator:
#Id #GeneratedValue(strategy=GenerationType.IDENTITY)
public Long getId() { ... }
You can't use Generators on composite keys
You can't do it with

I'm facing what I think is a simple problem with Hibernate, but can't solve it (Hibernate forums being unreachable certainly doesn't help).
I have a simple class I'd like to persist, but keep getting:
SEVERE: Field 'id' doesn't have a default value
Exception in thread "main" org.hibernate.exception.GenericJDBCException: could not insert: [hibtest.model.Mensagem]
at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103)
at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91)
[ a bunch more ]
Caused by: java.sql.SQLException: Field 'id' doesn't have a default value
[ a bunch more ]
The relevant code for the persisted class is:
package hibtest.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
#Entity
#Inheritance(strategy = InheritanceType.JOINED)
public class Mensagem {
protected Long id;
protected Mensagem() { }
#Id
#GeneratedValue
public Long getId() {
return id;
}
public Mensagem setId(Long id) {
this.id = id;
return this;
}
}
And the actual running code is just plain:
SessionFactory factory = new AnnotationConfiguration()
.configure()
.buildSessionFactory();
{
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
Mensagem msg = new Mensagem("YARR!");
session.save(msg);
tx.commit();
session.close();
}
I tried some "strategies" within the GeneratedValue annotation but it just doesn't seem to work. Initializing id doesn't help either! (eg Long id = 20L).
Could anyone shed some light?
EDIT 2: confirmed: messing with#GeneratedValue(strategy = GenerationType.XXX) doesn't solve it
SOLVED: recreating the database solved the problem
Sometimes changes made to the model or to the ORM may not reflect accurately on the database even after an execution of SchemaUpdate.
If the error actually seems to lack a sensible explanation, try recreating the database (or at least creating a new one) and scaffolding it with SchemaExport.
If you want MySQL to automatically produce primary keys then you have to tell it when creating the table. You don't have to do this in Oracle.
On the Primary Key you have to include AUTO_INCREMENT. See the example below.
CREATE TABLE `supplier`
(
`ID` int(11) NOT NULL **AUTO_INCREMENT**,
`FIRSTNAME` varchar(60) NOT NULL,
`SECONDNAME` varchar(100) NOT NULL,
`PROPERTYNUM` varchar(50) DEFAULT NULL,
`STREETNAME` varchar(50) DEFAULT NULL,
`CITY` varchar(50) DEFAULT NULL,
`COUNTY` varchar(50) DEFAULT NULL,
`COUNTRY` varchar(50) DEFAULT NULL,
`POSTCODE` varchar(50) DEFAULT NULL,
`HomePHONENUM` bigint(20) DEFAULT NULL,
`WorkPHONENUM` bigint(20) DEFAULT NULL,
`MobilePHONENUM` bigint(20) DEFAULT NULL,
`EMAIL` varchar(100) DEFAULT NULL,
PRIMARY KEY (`ID`)
)

Take a look at GeneratedValue's strategy. It typically looks something like:
#GeneratedValue(strategy=GenerationType.IDENTITY)
you must be using update in your hbm2ddl property. make the changes and update it to Create so that it can create the table.
<property name="hbm2ddl.auto">create</property>
It worked for me.
Dropping the table from the database manually and then re-running the application worked for me. In my case table was not created properly(with constraints) I guess.
I had this issue. My mistake was i had set the insertable and updatable fileds as false and was trying to set the field in the request. This field is set as NON NULL in DB.
#ManyToOne
#JoinColumn(name="roles_id", referencedColumnName = "id", insertable = false, updatable = false, nullable=false)
#JsonBackReference
private Role role;
Later I changed it to - insertable = true, updatable = true
#ManyToOne
#JoinColumn(name="roles_id", referencedColumnName = "id", insertable = true, updatable = true, nullable=false)
#JsonBackReference
//#JsonIgnore
private Role role;
It worked perfectly later.
I came here because of the error message, turns out I had two tables with the same name.
I had the same problem. I found the tutorial Hibernate One-To-One Mapping Example using Foreign key Annotation and followed it step by step like below:
Create database table with this script:
create table ADDRESS (
id INT(11) NOT NULL AUTO_INCREMENT,
street VARCHAR(250) NOT NULL,
city VARCHAR(100) NOT NULL,
country VARCHAR(100) NOT NULL,
PRIMARY KEY (id)
);
create table STUDENT (
id INT(11) NOT NULL AUTO_INCREMENT,
name VARCHAR(100) NOT NULL,
entering_date DATE NOT NULL,
nationality TEXT NOT NULL,
code VARCHAR(30) NOT NULL,
address_id INT(11) NOT NULL,
PRIMARY KEY (id),
CONSTRAINT student_address FOREIGN KEY (address_id) REFERENCES ADDRESS (id)
);
Here is the entities with the above tables
#Entity
#Table(name = "STUDENT")
public class Student implements Serializable {
private static final long serialVersionUID = 6832006422622219737L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
}
#Entity
#Table(name = "ADDRESS")
public class Address {
#Id #GeneratedValue
#Column(name = "ID")
private long id;
}
The problem was resolved.
Notice: The primary key must be set to AUTO_INCREMENT
Another suggestion is to check that you use a valid type for the auto-generated field. Remember that it doesn't work with String, but it works with Long:
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
public Long id;
#Constraints.Required
public String contents;
The above syntax worked for generating tables in MySQL using Hibernate as a JPA 2.0 provider.
Just add not-null constraint
I had the same problem. I just added not-null constraint in xml mapping. It worked
<set name="phone" cascade="all" lazy="false" >
<key column="id" not-null="true" />
<one-to-many class="com.practice.phone"/>
</set>
Maybe that is the problem with the table schema. drop the table and rerun the application.
In addition to what is mentioned above, do not forget while creating sql table to make the AUTO INCREMENT as in this example
CREATE TABLE MY_SQL_TABLE (
USER_ID INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
FNAME VARCHAR(50) NOT NULL,
LNAME VARCHAR(20) NOT NULL,
EMAIL VARCHAR(50) NOT NULL
);
When your field is not nullable it requires a default value to be specified on table creation. Recreate a table with AUTO_INCREMENT properly initialized so DB will not require default value since it will generate it by itself and never put NULL there.
CREATE TABLE Persons (
Personid int NOT NULL AUTO_INCREMENT,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
PRIMARY KEY (Personid)
);
https://www.w3schools.com/sql/sql_autoincrement.asp
I solved it changuing #GeneratedValue(strategy = GenerationType.IDENTITY) by #GeneratedValue(strategy = GenerationType.AUTO)
By the way i didn't need to put it to create, just:
spring.jpa.hibernate.ddl-auto: update
Please check whether the Default value for the column id in particular table.if not make it as default
I had the same problem. I was using a join table and all I had with a row id field and two foreign keys. I don't know the exact caused but I did the following
Upgraded MySQL to community 5.5.13
Rename the class and table
Make sure I had hashcode and equals methods
#Entity
#Table(name = "USERGROUP")
public class UserGroupBean implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name = "USERGROUP_ID")
private Long usergroup_id;
#Column(name = "USER_ID")
private Long user_id;
#Column(name = "GROUP_ID")
private Long group_id;
The same exception was thrown if a DB table had an old unremoved column.
For example:
attribute_id NOT NULL BIGINT(20), and attributeId NOT NULL BIGINT(20),
After removing the not used attribute, in my case contractId, the problem was resolved.
This happened to me with a #ManyToMany relationship. I had annotated one of the fields in the relationship with #JoinTable, I removed that and used the mappedBy attribute on #ManyToMany instead.
I tried the code and in my case the code below solve the issue. I had not settled the schema properly
#Entity
#Table(name="table"
,catalog="databasename"
)
Please try to add ,catalog="databasename" the same as I did.
,catalog="databasename"
In my case,
I altered that offending tables and the field "id" in question I made it AUTO_INCREMENT, I still need to figure out why on deployment time it was not making it "AUTO_INCREMENT" so that I have to do it by myself!
What about this:
<set name="fieldName" cascade="all">
<key column="id" not-null="true" />
<one-to-many class="com.yourClass"/>
</set>
I hope it helps you.
Try to change Long object type to long primitive type (if using primitives is ok for you).
I had the same problem and changing type helped me.
I had this issue, by mistake I had placed #Transient annotation above that particular attribute. In my case this error make sense.
"Field 'id' doesn't have a default value" because you didn't declare GenerationType.IDENTITY in GeneratedValue Annotation.
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
This issue is because sometimes you need to again update/create the database or sometimes if you have added the field in db table but not not entity class then it can not insert any null value or zero so this error came.
So check both side.Db and Entity class.
i have got such error in GCP cloud sql when model field didn't match correct table field in db.
Example:
when in model field is fieldName
table in db should have field field_name
Fixing table field name helped me.
I solved similar problem, when I altered the database column type , and did not add auto_increment. After adding back auto_increment in the alter table command (as in my original table creation) it worked
In my case I have not added the below property in my application.properties file:
spring.jpa.database-platform = org.hibernate.dialect.MySQL5InnoDBDialect
And added the following annotation to my entity class's Id column:
#GeneratedValue(strategy = GenerationType.IDENTITY)
And after adding this I have also drop my table manually from datatbase and run my project again that creates a new table with all default constraints for the table.
To delete just delete your schema is a really bad suggestion. There is a problem and it's best to find and fix it.
In my case I was using Envers this creates an Audit table for when entries are updated. But this audit table does not get updated itself it seems when the schema updates (At least not ID and it's relationships)
I just eddited the audit tables offending property and done. Everything back to normal.
To find what the issue is turn the following properties on in application.properties file
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
This will show you what SQL it is trying to executing and hopefully it will provide clarity on real issue.
Add a method hashCode() to your Entity Bean Class and retry it
