Hibernate 4 Save not working

Hibernate 4 Save not working - java

I'm new to hibernate 4 and I'm having some problem while saving a object using save(Object) method. My mapping files generated using reverse engineering are give below.
Event.java
#Entity
#Table(name = "event")
public class Event implements java.io.Serializable {
private Integer eventId;
private Set<EventCategory> eventCategories = new HashSet<EventCategory>(0);
public Event() {
}
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "EVENT_ID", unique = true, nullable = false)
public Integer getEventId() {
return this.eventId;
}
public void setEventId(Integer eventId) {
this.eventId = eventId;
}
#OneToMany(fetch = FetchType.LAZY, mappedBy = "event")
public Set<EventCategory> getEventCategories() {
return this.eventCategories;
}
public void setEventCategories(Set<EventCategory> eventCategories) {
this.eventCategories = eventCategories;
}
}
category.java
#Entity
#Table(name = "category")
public class Category implements java.io.Serializable {
private Integer categoryId;
private Set<EventCategory> eventCategories = new HashSet<EventCategory>(0);
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "CATEGORY_ID", unique = true, nullable = false)
public Integer getCategoryId() {
return this.categoryId;
}
public void setCategoryId(Integer categoryId) {
this.categoryId = categoryId;
}
#OneToMany(fetch = FetchType.LAZY, mappedBy = "category")
public Set<EventCategory> getEventCategories() {
return this.eventCategories;
}
public void setEventCategories(Set<EventCategory> eventCategories) {
this.eventCategories = eventCategories;
}
}
EventCategory.java
#Entity
#Table(name = "event_category")
public class EventCategory implements java.io.Serializable {
private EventCategoryId id;
private Event event;
private Category category;
public EventCategory() {
}
public EventCategory(EventCategoryId id) {
this.id = id;
}
public EventCategory(EventCategoryId id, Event event, Category category) {
this.id = id;
this.event = event;
this.category = category;
}
#EmbeddedId
#AttributeOverrides({
#AttributeOverride(name = "eventId", column = #Column(name = "EVENT_ID")),
#AttributeOverride(name = "categoryId", column = #Column(name = "CATEGORY_ID")) })
public EventCategoryId getId() {
return this.id;
}
public void setId(EventCategoryId id) {
this.id = id;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "EVENT_ID", insertable = false, updatable = false)
public Event getEvent() {
return this.event;
}
public void setEvent(Event event) {
this.event = event;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "CATEGORY_ID", insertable = false, updatable = false)
public Category getCategory() {
return this.category;
}
public void setCategory(Category category) {
this.category = category;
}
}
All these files are generated using hbm2java (reverse engineering). But i couldn't able to save values using the below code. And also I'm not getting any exception while running this piece of code.
EventCategory eventCategory = new EventCategory();
eventCategory.setEvent(event);
eventCategory.setCategory(category);
eventCategory.setId(eventCategoryId);
getSession().save( eventCategory );
Please help me to resolve my problem

You need a transaction.
EventCategory eventCategory = new EventCategory();
eventCategory.setEvent(event);
eventCategory.setCategory(category);
eventCategory.setId(eventCategoryId);
Session session = getSession();
Transaction transaction = session.beginTransaction();
session.save( eventCategory );
transaction.commit();

How to join table with itself using another table in hibernate with annotations?

I have two tables - users and friends.
Any user may have any number of friends (another users). These relationships are stored in a table 'friends', so this is just service table.
Pricture of relationships
How should I code this in my entity classes? Should I use #ManyToMany?
My presumption is the next:
User.java:
#Entity
#Table(name = "users")
#NoArgsConstructor
public class User implements Serializable {
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Id
#Column(name = "id")
private Long id;
#Basic
#Column(name = "name", nullable = false, length = 45)
private String name;
#ManyToMany(cascade = { CascadeType.ALL })
#JoinTable(
name = "friends",
joinColumns = { #JoinColumn(name = "id") },
inverseJoinColumns = { #JoinColumn(name = "sender") }
)
private Set<User> friendsInviters = new HashSet<>();
#ManyToMany(mappedBy = "users")
private Set<User> friendsReceiver = new HashSet<>();
}
Friend.java:
#Entity
#Table(name = "friends")
#NoArgsConstructor
public class Friend implements Serializable {
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Id
#Column(name = "id")
private Long id;
#Basic
#Column(name = "sender")
private Long sender;
#Basic
#Column(name = "receiver")
private Long receiver;
}
P.S. - i just started to learn Hibernate:)

#Entity
#Table(name = "users")
public class User implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long userId;
#Column(name = "name", nullable = false, length = 45)
private String name;
#ManyToMany(cascade = { CascadeType.ALL })
#JoinTable(name="users_friends",
joinColumns = { #JoinColumn(name = "user_id") },
inverseJoinColumns = { #JoinColumn(name = "friend_id") }
)
private Set<User> friendsInviters = new HashSet<>();
#ManyToMany(mappedBy = "friendsInviters")
private Set<User> friendsReceiver = new HashSet<>();
public Long getUserId() {
return userId;
}
public void setUserId(Long userId) {
this.userId = userId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Set<User> getFriendsInviters() {
return friendsInviters;
}
public void setFriendsInviters(Set<User> friendsInviters) {
this.friendsInviters = friendsInviters;
}
public Set<User> getFriendsReceiver() {
return friendsReceiver;
}
public void setFriendsReceiver(Set<User> friendsReceiver) {
this.friendsReceiver = friendsReceiver;
}
}

Why CriteriaQuery is putting dot in hibernate string?

I have a problem with my multiselect. I'm using it as an Specification with multiple joins. I don't know why hibernate decides to put a dot in the query. the error is shown below in the query. this is the constructor I'm using
public HelperOutput(Long id,
String personName,
Long helperTypeId,
String helperTypeTitle,
String agencyTitle,
String regionalOfficeTitle,
String basketPartTitle,
YesNo allowedToOperate,
YesNo hasFlatTirePack,
Long fleetRescueId,
Long cityId,
String cityName,
Long skillLevel,
String helperRankTitle,
Long personId,
Long helperRate,
String personelId,
Long regionalOfficeId,
Long basketPartId,
String mobile,
String fleetName,
ExpertType expertType,
Long maxConcurrentWork,
Set<Long> dutyCityIds
) {
this.id = id;
this.helperTypeId = helperTypeId;
this.helperTypeTitle = helperTypeTitle;
this.agencyTitle = agencyTitle;
this.regionalOfficeId = regionalOfficeId;
this.regionalOfficeTitle = regionalOfficeTitle;
this.basketPartTitle = basketPartTitle;
this.fleetRescueId = fleetRescueId;
this.cityId = cityId;
this.helperRankTitle = helperRankTitle;
this.personId = personId;
this.basketPartId = basketPartId;
this.mobile = mobile;
this.fleetName = fleetName;
this.cityName = cityName;
this.personName = personName;
this.allowedToOperate = allowedToOperate;
this.hasFlatTirePack = hasFlatTirePack;
this.skillLevel = skillLevel;
this.helperRate = helperRate;
this.personelId = personelId;
this.expertType = expertType;
this.maxConcurrentWork = maxConcurrentWork;
this.dutyCityIds = dutyCityIds;
}
this is the multiselect which is similar to the constructor.
cq.multiselect(root.get(Helper_.ID),
personName,
helperHelperTypeJoin.get(HelperType_.ID),
helperHelperTypeJoin.get(HelperType_.TITLE),
helperAgencyJoin.get(Agency_.TITLE),
helperRegionalOfficeJoin.get(RegionalOffice_.TITLE)
, helperBasketPartJoin.get(Basket_.TITLE),
root.get(Helper_.ALLOWED_TO_OPERATE),
root.get(Helper_.HAS_FLAT_TIRE_PACK),
fleetRescueJoin.get(HelperFleet_.ID),
helperCityJoin.get(City_.ID) ,
helperCityJoin.get(City_.NAME),
root.get(Helper_.SKILL_LEVEL),
helperRankJoin.get(HelperRank_.NAME),
helperPersonJoin.get(Person_.ID),
root.get(Helper_.helperRate),
root.get(Helper_.personelId),
helperRegionalOfficeJoin.get(RegionalOffice_.ID),
helperBasketPartJoin.get(Basket_.ID),
helperPersonJoin.get(Person_.MOBILE),
HelperFleetJoin.get(Fleet_.NAME),
root.get(Helper_.EXPERT_TYPE),
root.get(Helper_.MAX_CONCURRENT_WORK),
root.get(Helper_.DUTY_CITIES)
);
this is the hibernate query which I don't know why it has a dot.

I answered it in a comment in Helper entity. the answer is you shouldn't make a mistake in mappedBy attribute in #OneToMany annotation. so I changed dutyCityId to helper now it's working.
before it was joining with another condition helper.ID = helperDutyCity.dutyCityId which was wrong now it joins with this condition helper.ID = helperDutyCity.helperId which is correct.

Spring boot JPA save manytomany relationship

I am trying to store a manytomany relationship but it not stores the relationship.
The following code has generated 3 tables.
Soldier, medal and soldier_medals.
The service just make a call to a CRUD Interface with save(soldier).
It stores correctly the soldier, but it not fill any row at the soldier_medals table.
This is the JSON I send to the server:
{
"abbreviatedSequence": "XDF",
"medals": [
{
"name": "Purple",
"id": 1
},
{
"name": "Red",
"id": 2
}
],
"sequence": "XDFREE",
"name": "Savier"
}
Employee.java
#Entity(name="employees")
#Inheritance(strategy=InheritanceType.SINGLE_TABLE)
public class Employee {
#Id
#GeneratedValue(generator="increment")
#GenericGenerator(name="increment", strategy = "increment")
private Long id;
private String 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;
}
}
Soldier.java
#Entity(name="soldier")
public class Soldier extends Employee{
private String sequence;
private String abbreviatedSequence;
#ManyToMany(fetch = FetchType.LAZY, mappedBy = "soldiers")
private List<Medal> medals;
public List<Medal> getMedals() {
return medals;
}
public void setMedals(List<Medal> medals) {
this.medals = medals;
}
public String getSequence() {
return sequence;
}
public void setSequence(String sequence) {
this.sequence = sequence;
}
public String getAbbreviatedSequence() {
return abbreviatedSequence;
}
public void setAbbreviatedSequence(String abbreviatedSequence) {
this.abbreviatedSequence = abbreviatedSequence;
}
}

SoldierController.java
#RestController
public class SoldierController {
#Autowired
private SoldierService soldierService;
#RequestMapping(value="/api/contextsource/soldier",method= RequestMethod.POST)
public Soldier addSoldier(#RequestBody Soldier soldier) {
return soldierService.addSoldier(soldier);
}
}

I was persisting the entity with in the wrong order. This is how I solved it.
#RequestMapping(value="/api/contextsource/soldier",method= RequestMethod.POST)
public Soldier addPeptide(#RequestBody Soldier soldier) {
for(Medal s: soldier.getMedals()) {
Medal ss = medalService.getMedalById(s.getId());
ss.getMedals().add(soldier);
medalService.addMedal(ss);
}
return null;
}

Did you try this in Soldier entity class like medal entity class:
#ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinTable(name = "soldier_medals", joinColumns = {
#JoinColumn(name = "soldier_id", nullable = false, updatable = false) },
inverseJoinColumns = { #JoinColumn(name = "medal_id",
nullable = false, updatable = false) })
private List<Medal> medals;
instead of this :
#ManyToMany(fetch = FetchType.LAZY, mappedBy = "soldiers")
private List<Medal> medals;

Error :- org.hibernate.PropertyAccessException: could not get a field value by reflection getter

I have Class Customer ,User , Customer has property manager of user class
Class Customer {
/** The manager. */
#ManyToOne(optional = false, cascade = {CascadeType.PERSIST, CascadeType.REFRESH, CascadeType.MERGE})
#JoinColumn(name = "MANAGER")
#JsonSerialize(using = EntitySerializer.class)
#JsonDeserialize(using = UserDeserializer.class)
private User manager;
}
-------------------------------------
Class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO, generator = User.TABLE_NAME + "_SEQUENCE")
#SequenceGenerator(name = User.TABLE_NAME + "_SEQUENCE", sequenceName = User.TABLE_NAME + "_SEQ")
#Column(name = FIELD_ID, nullable = false)
#SuppressWarnings("PMD.ShortVariable")
private Integer id;
#Override
public Integer getId() {
return id;
}
#Override
public void setId(final Integer newId) {
//System.out.println("setID");
id = newId;
}
}
Now when i am trying to create criteria
final Criteria criteria = getSession().createCriteria(Customer.class);
criteria.add(Restrictions.ilike("manager", "%"+searchTerm+"%"))
It throwing Error :-
org.hibernate.PropertyAccessException: could not get a field value by reflection getter of com.User.id
Caused by:
java.lang.IllegalArgumentException: Can not set java.lang.Integer field com.User.id to java.lang.String
**Id field is integer **

Could you please change the following:
final Criteria criteria = getSession().createCriteria(Customer.class); criteria.add(Restrictions.ilike("manager", "%"+searchTerm+"%"))
by the following:
final Criteria criteria = getSession().createCriteria(Customer.class); criteria.add(Restrictions.ilike("manager.name", "%"+searchTerm+"%"))
LIKE clause is applicable to text column only.

this code to used
return this.sessionFactory.getCurrentSession()
.createCriteria(UserTraining.class)
.add(Restrictions.eq("userProfile.userId", userId))
.list();

You used this annotation to error remove
#Table(name="user_training")
#Entity
public class UserTraining {
#Id
#GeneratedValue
#Column(name="id")
private int id;
//Generate getter setter of id
/*
#Column(name="user_id")

private UserProfile userProfile;
public UserProfile getUserProfile() {

public void setUserProfile(UserProfile userProfile) {
this.userProfile = userProfile;
}

how to write delete query in hibernate for many to many relationship

I have two beans user and virtualdomain
#Entity
#Table(name = "tblUser")
public class User implements Serializable {
private Long id;
private String username;
private String deleteflag;
private Set<VirtualDomain> virtualdomainset;
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.AUTO)
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Column(name = "username", length = 50, nullable = false)
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
#Column(name = "deleteflag")
public String getDeleteflag() {
return deleteflag;
}
public void setDeleteflag(String deleteflag) {
this.deleteflag = deleteflag;
}
#ManyToMany(targetEntity = VirtualDomain.class, cascade = {CascadeType.PERSIST},fetch=FetchType.EAGER)
#JoinTable(name = "tblUserDomainRel", joinColumns = #JoinColumn(name = "userid"), inverseJoinColumns = #JoinColumn(name = "domainid"))
public Set<VirtualDomain> getVirtualdomainset() {
return virtualdomainset;
}
public void setVirtualdomainset(Set<VirtualDomain> virtualdomainset) {
this.virtualdomainset = virtualdomainset;
}
}
#Entity
#Table(name = "tblVirtualDomain")
public class VirtualDomain {
private Long id;
private String domainname;
private String deleteflag;
private Set<User> userset;
#Id
#JoinColumn(name = "id")
#GeneratedValue(strategy = GenerationType.AUTO)
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Column(name = "domain_name")
public String getDomainname() {
return domainname;
}
public void setDomainname(String domainname) {
this.domainname = domainname;
}
#Column(name = "deleteflag")
public String getDeleteflag() {
return deleteflag;
}
public void setDeleteflag(String deleteflag) {
this.deleteflag = deleteflag;
}
#ManyToMany(cascade = {CascadeType.ALL},fetch=FetchType.EAGER, mappedBy = "virtualdomainset", targetEntity = User.class)
public Set<User> getUserset() {
return userset;
}
public void setUserset(Set<User> userset) {
this.userset = userset;
}
}
Now when I delete some user i use to set the deleteflag which means that the data remains in the database.
My requirement is that the user whose delete flag is set must be removed from the tblUserDomainRel table so how to write that delete query.

just remove the virtualDomain from the collection on the User and remove the other side for completeness
// on User
public void removeVirtualDomain(VirtualDomain vd){
virtualDomainset.remove(vd);
vd.getUserset().remove(this)
}
this will remove the relationship record. Or to remove a user from all virtual Domains:
// on User
public void removeFromAllVirtualDomains(){
for( VirtualDomain vd : virtualdomainset ){
vd.getUserset().remove(this);
}
virtualDomainset.clear();
}
