I have a 1-Many mapping for the Role-Policy table described and the POJO as follows
#Entity
#Table(name="policy")
public class AWSPolicy implements Serializable{
#Id
#GeneratedValue
#Column(name = "policyId")
private int policyId;
#Column(name = "policyName")
private String policyName;
#ManyToOne
#JoinColumn(name="roleId")
private Role role;
public AWSRole getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
public int getPolicyId() {
return policyId;
}
public void setPolicyId(int policyId) {
this.policyId = policyId;
}

}

}
}
#Entity
#Table(name="role")
public class Role implements Serializable{
#Column(name = "rolename")
private String rolename;
#Id
#GeneratedValue
#Column(name = "roleId")
private int roleId;
#Column(name = "roleDescription")
private String roleDescription;
#OneToMany(cascade=CascadeType.PERSIST, mappedBy = "role")
private Set<AWSPolicy> policies;
public Set<AWSPolicy> getPolicies() {
return policies;
}
public void setPolicies(Set<AWSPolicy> policyList) {
this.policies = policyList;
}
public int getRoleId() {
return roleId;
}
public void setRoleId(int roleId) {
this.roleId = roleId;
}
public String getRolename() {
return rolename;
}
public void setRolename(String rolename) {
this.rolename = rolename;
}
public String getRoleDescription() {
return roleDescription;
}
public void setRoleDescription(String roleDescription) {
this.roleDescription = roleDescription;
}
}
The issue is that when I try to insert into the table , it inserts only into the Role table but not the policy table. Can someone help me with this.
Role role = new Role();
Set<Policy> policyList = new HashSet<Policy>();
Policy policy = new Policy();
policy.setPolicyName("uberpolicy");
policyList.add(policy);
role.setRolename("uberrole");
role.setRoleDescription("uberrole");
role.setPolicies(policyList);
Session session = getSessionFactory().getCurrentSession();
session.save(role);
May be this example will help you
http://www.mkyong.com/hibernate/hibernate-one-to-many-relationship-example-annotation/
http://viralpatel.net/blogs/hibernate-one-to-many-annotation-tutorial/
Can you please remove cascade=CascadeType.PERSIST and try.
Can you please write output of you query so I can help you.
I tried the code that you post. I see the insert queries being executed on the ROLE and POLICY tables but the value in roleId column of the POLICY table is null. This is because you have set the role object in the policy instance. You have to set both ends of a relationship.
The below code should update the foreign key value
Role role = new Role();
Set<Policy> policyList = new HashSet<Policy>();
Policy policy = new Policy();
policy.setPolicyName("uberpolicy");
policy.setRole(role); //Set the role object in the policy through a setter.
policyList.add(policy);
role.setRolename("uberrole");
role.setRoleDescription("uberrole");
role.setPolicies(policyList);
Session session = getSessionFactory().getCurrentSession();
session.save(role);
Below is the fix
#Entity
#Table(name="cas_aws_role")
public class AWSRole implements Serializable{
#Column(name = "casAWSRolename")
private String casAWSRolename;
#Id
#GeneratedValue
#Column(name = "casAWSRoleId")

Debug SQL Query From Hibernate
Hibernate:

Why is Hibernate Selecting from the Product Table And not From the Book Table?
Is there a way how to solve this problem?

I've also tried to make this relationship bidirectional and it didn't work, so I may be missing something
Also before this I had achievement objects instead of achievementId on joinedUserAchievement, it worked but I think its not what I need, I don't need to get every achievement object always, with only the id is fine.
From the docs:
Relationship mappings defined within an embedded id class are not supported
You should put the ids only in JoinedUserAchievementId, and put User and Achievement associations in JoinedUserAchievement directly like so:
public class JoinedUserAchievementId {
private Long userId;
private Long achievementId;
...
}
public class JoinedUserAchievement {
#EmbeddedId
private JoinedUserAchievementId joinedUserAchievementId;
#ManyToOne
#MapsId("userId")
#JoinColumn(name = "USER_ID")
private User user;
#ManyToOne(optional = false, fetch = LAZY)
#MapsId("achievementId")
#JoinColumn(name = "ACHIEVEMENT_ID")
private Achievement achievement;
//if you absolutely need to map the achievement_id column here as well
//note that it will already be mapped to joinedUserAchievementId.achievementId
#Column(name = "ACHIEVEMENT_ID", insertable=false, updatable=false)
private Long achievementId;
...
}
Remember to update the User.joinedUserAchievementList mapping to mappedBy="user".
Hello I have just started learning hibernate. Please correct me where I am doing mistake. I want do a one-to-many relationship between two tables using a join table using hibernate annotations.
create table assembly
(
assembly_id serial primary key,
number text,
user_id int
);
create table assembly_properties
(
property_id serial primary key,
property_name text,
property_type text

assembly_id int,
property_id int,
property_value text,
CONSTRAINT FK_assembly_id FOREIGN KEY (assembly_id) REFERENCES assembly(assembly_id),

Hibernate can't handle when the annotations for public setters and private fields are mixed in one class.
A possible solution would be to make all of your annotations at the public setters instead of mixing it between the private fields and the public setters, that way you can avoid the case where there are annotations both at public and private access modifiers.
Your annotations are conflicting. this:
#Column
#ElementCollection(targetClass = AssemblyProperties.class)
private Set<AssemblyProperties> assembly_properties;
and this:
#OneToMany(targetEntity = AssemblyProperties.class, cascade = CascadeType.ALL)
#JoinTable(name = "assembly_properties_mapping", joinColumns = { #JoinColumn(name = "assembly_id") }, inverseJoinColumns = { #JoinColumn(name = "property_id") })
public Set<AssemblyProperties> getAssembly_properties() {
return assembly_properties;
}
just remove first annotaions over private field (assembly_properties).
in enthesaplasmaek entity, i made relationship as below with my two entities, EntHesaplasma and EntHesaplasmaek
#OneToOne(fetch=FetchType.LAZY)
#JoinColumn(name="hesaplasmaekid",referencedColumnName="carihareketid",insertable=false,updatable=false)
#Where(clause = "enthesaplasma.evraktip='EK'")
public EntHesaplasma getEnthesaplasma() {
return enthesaplasma;
}
when i run the below hql , hibernate makes a relationship between hesaplasmaekid and hesaplasmaid (primary key (#Id) of enthesaplasma entity). But the correct relationship should be between carihareketid in enthesaplasma entity and enthesaplasmaekid in the enthesaplasmaek entity.
select hs.hesaplasmaid,hs.carihareketid,ek.hesaplasmaekid,hs.hesaplasmano,ek.aciklama from EntHesaplasmaek ek left join ek.enthesaplasma hs

A bit late, but got into the same problem.
It's not a bug that you can't set up bidirectional relation, one side need to use JoinColumn, another map it via mappedBy. So yes..the solution here is correct!
I found the explanation here:
How do I join tables on non-primary key columns?
this seems a bug in hibernate. but i solved my problem with mappedby annotation.
i added a field to my enthesaplasma entity as below. i defined the relationship in this entity.
#OneToOne(fetch=FetchType.LAZY)
#JoinColumn(name="carihareketid",insertable=false,updatable=false)
public EntHesaplasmaek getEnthesaplasmaek() {
return enthesaplasmaek;
}
public void setEnthesaplasmaek(EntHesaplasmaek enthesaplasmaek) {
this.enthesaplasmaek = enthesaplasmaek;
}
i updated my other entity as below.
#OneToOne(fetch=FetchType.LAZY,mappedBy="enthesaplasmaek")
public EntHesaplasma getEnthesaplasma() {
return enthesaplasma;
}
public void setEnthesaplasma(EntHesaplasma enthesaplasma) {
this.enthesaplasma = enthesaplasma;
}
Addition info and question : in this link, it is said that referencedcolumnname is used, when there is a composite P.K in an entity. is this correct ?
(from What is referencedColumnName used for in JPA? )
Quoting API on referencedColumnName:
The name of the column referenced by this foreign key column.
Default (only applies if single join column is being used): The same name as the primary key column of the referenced table.
Q/A
Where this would be used?
When there is a "composite PK" in referenced table, then you need to
specify column name you are referencing.
I'm using Jersey + spring + hibernate4.17 to develop api system； The problem is if the cleaFields is called twice at same time, the 2nd call will throw an exception as below,

The clearFields method in the Controller,
#Transactional(isolation=Isolation.REPEATABLE_READ)
public void clearFields(Integer userId) {
User user = this.userDao.get(userId);
user.getFields().clear();
userDao.flush(); //call the current session.flush(); this line can throw exception.
}
User Entity class
#Entity
#Table(name="users")
#NamedQuery(name="User.findAll", query="SELECT u FROM User u")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name="id", unique = true, nullable = false)
private int userId;

public List<UserProfile> getFields() {

UserProfile class,
#Entity
#Table(name="user_profiles")
public class UserProfile implements Serializable {

#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
#Column(name="field_name")
private String fieldName;
#ManyToOne(targetEntity = User.class, fetch = FetchType.LAZY)
#JoinColumn(name="user_id")
private User user;
private String value;
public UserProfile() {
}
public Integer getId() {
return this.id;

public void setId(Integer id) {
this.id = id;
}
public String getFieldName() {
return this.fieldName;
}
public void setFieldName(String fieldName) {
this.fieldName = fieldName;
}
public String getValue() {
return this.value;
}
public void setValue(String value) {
this.value = value;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
I did some research, the root cause is if the 2nd calling get some fields, and before delete them, the 1st calling already delete all fields from database.
In another word, the 2nd calling try to delete some records which already were deleted by others.
How can I solve the problem?
