Hibernate mapping and query - java

The hibernate mapping of my hbm.xml is:
<class name="UserCalendar" table="user_calendar">
<id name="userCalendarId" column="user_calendar_id" type="long">
<generator class="native" />
</id>
<property name="userId" column="user_id" type="long" not-null="true"/>

<property name="deadline" column="deadline" type="date"/>
<property name="ticketType" column="ticket_type" type="integer"/>
<property name="isCurrentlyAssigned" column="is_currently_assigned" type="boolean"/>
</class>
The UserCalendar.java:
public class UserCalendar implements Serializable {
private static final long serialVersionUID = 10172L;
private long userCalendarId;
private long userId;
private String userLoginName;
private String userName;
private List<UserDate> userDates;
public UserCalendar() {
}
public long getUserCalendarId() {
return userCalendarId;
}
public void setUserCalendarId(long userCalendarId) {
this.userCalendarId = userCalendarId;
}
public long getUserId() {
return userId;
}
public void setUserId(long userId) {
this.userId = userId;
}
public String getUserLoginName() {
return userLoginName;
}
public void setUserLoginName(String userLoginName) {
this.userLoginName = userLoginName;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public List<UserDate> getUserDates() {
return userDates;
}
public void setUserDates(List<UserDate> userDates) {
this.userDates = userDates;
}
}
The UserDate.java:
public class UserDate implements Serializable {
private static final long serialVersionUID = 10173L;
private long userDateId;
private Date date;
private List<UserItem> userItems;
public UserDate() {
}
public long getUserDateId() {
return userDateId;
}
public void setUserDateId(long userDateId) {
this.userDateId = userDateId;
}
public void setDate(Date date) {
this.date = date;
}
public Date getDate() {
return date;
}
public List<UserItem> getUserItems() {
return userItems;
}
public void setUserItems(List<UserItem> userItems) {
this.userItems = userItems;
}
}
And the UserItem.java:
public class UserItem implements Serializable {
private static final long serialVersionUID = 10174L;
public static final int AUTO = 1;
public static final int EQUAL = 2;
public static final int CUSTOM = 3;
public static final int CUSTOM_EQUAL = 4;
public static final int GENERAL_TICKET = 5;
public static final int SPECIAL_TICKET_HALF = 6;
public static final int SPECIAL_TICKET_FULL = 7;
private long userItemId;
private long spaceId;
private String spaceName;
private long itemId;
private String itemRefId;
private double allocation;
private int scheduledStrategy;
private double utilization;
private Date deadline;
private int ticketType;
private boolean isCurrentlyAssigned;
public UserItem() {
}
public long getUserItemId() {
return userItemId;
}
public void setUserItemId(long userItemId) {
this.userItemId = userItemId;
}
public long getSpaceId() {
return spaceId;
}
public void setSpaceId(long spaceId) {
this.spaceId = spaceId;
}
public long getItemId() {
return itemId;
}
public void setItemId(long itemId) {
this.itemId = itemId;
}
public double getAllocation() {
return allocation;
}
public void setAllocation(double allocation) {
this.allocation = allocation;
}
public int getScheduledStrategy() {
return scheduledStrategy;
}
public void setScheduledStrategy(int scheduledStrategy) {
this.scheduledStrategy = scheduledStrategy;
}
public double getUtilization() {
return utilization;
}
public void setUtilization(double utilization) {
this.utilization = utilization;
}
public Date getDeadline() {
return deadline;
}
public void setDeadline(Date deadline) {
this.deadline = deadline;
}
public int getTicketType() {
return ticketType;
}
public void setTicketType(int ticketType) {
this.ticketType = ticketType;
}
public String getSpaceName() {
return spaceName;
}
public void setSpaceName(String spaceName) {
this.spaceName = spaceName;
}
public String getItemRefId() {
return itemRefId;
}
public void setItemRefId(String itemRefId) {
this.itemRefId = itemRefId;
}
public boolean isCurrentlyAssigned() {
return isCurrentlyAssigned;
}
public void setCurrentlyAssigned(boolean isCurrentlyAssigned) {
this.isCurrentlyAssigned = isCurrentlyAssigned;
}
}
Now I want to select those UserCalendar object which has a specific itemId. In my thought if I insert userCalendarId in UserItem and execute
SELECT USERCALENDAR
FROM USER_CALENDAR
WHERE USERCALENDAR.USERCALENDARID IN
(SELECT USERCALENDARID
FROM USERITEM
WHERE USERITEM.ITEMID=ID)
then it might be possible.
Am I right?
How can I insert userCalendarId in UserItem? What is the mapping needed for this?
Thanks and regards.


To have one-to-many you will need column in UserDate that refers to UserCalendar.userCalendarId and column in UserItem to refer to UserDate.userDateId. You will need to specify those columns via many-to-one in those classes.
Then you can use join
SELECT * FROM user_calendar uc
JOIN user_date ud ON ud.user_calendar_id=uc.user_calendar_id
JOIN user_item ui ON ui.user_date_id=ud.user_date_id
WHERE ui.user_item_id=<your value>
Assuming that you have those new columns user_calendar_id and user_date_id in user_date and user_item.
In HQL it will be simpler but I don't remember on top of my head. Check docs.
It could be something like
select ui.userDate.userCaledar from UserItem ui where ui.userItemId=:id
Provided that you added properties userDate and userCalendar via many-to-one

if yes how did you resolve it? Please help me with issue.
I appreciate your responses in advance. Thank you!!!!!!!!!!!!!!

In your java code, change a name of many to one relation, to anything but the current:
#ManyToOne
#JoinColumn(name="BATCH_JOB_CONFIG_ID", referencedColumnName="BATCH_JOB_CONFIG_ID")
private BatchJobConfigDetails batchJobConfigDtl;
something like
#ManyToOne
#JoinColumn(name="MY_NEW_NAME", referencedColumnName="BATCH_JOB_CONFIG_ID")
private BatchJobConfigDetails batchJobConfigDtl;
and also change it in your hbm.xml file appropriately.
UPDATE:
Also, change a name of columns in your hbl.xml file. One second.
from
<many-to-one name="BatchJobConfigDetails" column="BATCH_JOB_CONFIG_ID"
class="BatchJobConfigDetails" not-null="true" />
to
<many-to-one name="BatchJobConfigDetails" column="MY_NEW_NAME"
class="BatchJobConfigDetails" not-null="true" />

In your mapping, you have this
<set name="labJoin" fetch="join">
<key column="CODIGO_LAB" />
<one-to-many class="com.mycompany.mavenproject1.Laboratorio"/>
</set>
But property labJoin has type int. The type of this property has to be Set<Laboratorio>.

Perform two save("entity-name",object) in a single session of hibernate?

I have a POJO class NewUniversity.java. I've created a mapping file for it viz. RegisterAction.hbm.xml. Now the problem is when I try to call the save methods from DAO class, only the first one gets executed, the second one doesn't. I've two tables linked to one entity through 'entity-mapping' attribute in the xml file.
File: NewUniversity.java
public class NewUniversity implements Serializable {
// University fields
private String uCode;
private String uName;
private String uAddress;
private String uCity;
private String uState;
private long uContactNo;
private String uEmail;
// University director fields
private String name;
private String address;
private String city;
private String state;
private long contactNo;
private String email;
private String userName;
private String pwd;
public String getuCode() {
return uCode;
}
public void setuCode(String uCode) {
this.uCode = uCode;
}
public String getuName() {
return uName;
}
public void setuName(String uName) {
this.uName = uName;
}
public String getuAddress() {
return uAddress;
}
public void setuAddress(String uAddress) {
this.uAddress = uAddress;
}
public String getuCity() {
return uCity;
}
public void setuCity(String uCity) {
this.uCity = uCity;
}
public String getuState() {
return uState;
}
public void setuState(String uState) {
this.uState = uState;
}
public long getuContactNo() {
return uContactNo;
}
public void setuContactNo(long uContactNo) {
this.uContactNo = uContactNo;
}
public String getuEmail() {
return uEmail;
}
public void setuEmail(String uEmail) {
this.uEmail = uEmail;
}
// University directors setters/getters
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {

return contactNo;
}

this.contactNo = contactNo;

public String getEmail() {

this.email = email;

transaction.commit();
session.close();
} catch (Exception e) {
transaction.rollback();
e.printStackTrace();
session.close();
}
}
I've tried using persist() as well. But no luck!
The point is, when I perform it on two different sessions, it works perfectly. (All the objects value are coming through .jsp to struts). For some reasons I didn't use annotations.

Maybe it is because Session#save(entityName, object) method requires object to be a "transient" object (i.e. that has not already been persisted), and that, after the first call to session.save("university", user); then user is no more transient.
Persist the given transient instance, first assigning a generated
identifier. (Or using the current value of the identifier property if
the assigned generator is used.) This operation cascades to associated
instances if the association is mapped with cascade="save-update"
What happens when you make a get of your persisted "university" entity just after the first save, and then save it as "uniDirector" ?

hibernate dynamic component equivalent annotation

What is the equivalent way of defining dynamic component in hibernate by annotations?
public abstract class CustomizableEntity {
private Map customProperties;
public Map getCustomProperties() {
if (customProperties == null)
customProperties = new HashMap();
return customProperties;
}
public void setCustomProperties(Map customProperties) {
this.customProperties = customProperties;
}
public Object getValueOfCustomField(String name) {
return getCustomProperties().get(name);
}
public void setValueOfCustomField(String name, Object value) {
getCustomProperties().put(name, value);
}
}
my entity:
public class Contact extends CustomizableEntity {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
hibernate xml:
<hibernate-mapping auto-import="true" default-access="property" default-cascade="none" default-lazy="true">
<class abstract="false" name="com.enterra.customfieldsdemo.domain.Contact" table="tbl_contact">
<id column="fld_id" name="id">
<generator class="native"/>
</id>
<property name="name" column="fld_name" type="string"/>
<dynamic-component insert="true" name="customProperties" optimistic-lock="true" unique="false" update="true">
</dynamic-component>
</class>
</hibernate-mapping>
I want to use a dynamic-component by HashMap to create entities at runtime.

Read data from table where primary key is composite using hibernate

I have these POJO classes in my project.
public class MerchantChainUser extends com.avanza.ni.common.dto.AbstractDTO
implements java.io.Serializable {
private long chainId;
private CompositePK compositePK;
public MerchantChainUser() {
}
public void setChainId(long chainId) {
this.chainId = chainId;
}
public long getChainId() {
return chainId;
}
public void setCompositePK(CompositePK compositePK) {
this.compositePK = compositePK;
}
public CompositePK getCompositePK() {
return compositePK;
}
}
AND
public class CompositePK implements Serializable {
private long merchantId;
private long userId;
public void setMerchantId(long merchantId) {
this.merchantId = merchantId;
}
public long getMerchantId() {
return merchantId;
}
public void setUserId(long userId) {
this.userId = userId;
}
public long getUserId() {
return userId;
}
}
hbm.xml file for MerchantUserChain is
<hibernate-mapping>
<class name="com.avanza.ni.portal.dto.MerchantChainUser" table="MERCHANT_CHAIN_USER">
<composite-id name="compositePK">
<key-property name="merchantId" type="long" column="MERCHANT_ID"></key-property>
<key-property name="userId" type="long" column="MERCHANT_USER_ID"></key-property>
</composite-id>
<property name="chainId" type="long">
<column name="MERCHANT_CHAIN_ID" length="38" />
</property>
</class>
Now what i wanted is i have to read data from the table using just MERCHANT_USER_ID. I am able to retreive whole data from the table but now i want to set a criteria as Only give me those row that MERCHANT_USER_ID is specific. I didn't know how to write data criteria.

the answer that i put the comment has been deleted, so i post it here :D
Criteria crit = session.createCriteria(MerchantChainUser.class)
.add(Restrictions.eq("compositePK.userId", userId));
or with hql
session.createQuery("from MerchantChainUser where compositePK.userId = :userid").setParameter("userid",userid);

Can you try:
Criteria crit = session.createCriteria(MerchantChainUser.class);
crit.add(Restrictions.eq("compositePK.merchantId", 42));
crit.add(Restrictions.eq("compositePK.userId", 43));
crit.setMaxResults(10);
List result = crit.list();
