"java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name", although attribute is set

Hibernate 5.6 with Spring 5.3 here.
When creating predicates to fetch data from a table with this code:
CriteriaBuilder cb = this.getSession().getCriteriaBuilder();
CriteriaQuery cq = cb.createQuery(aliasToBeanClass);
Root root = cq.from(aliasToBeanClass); // aliasToBeanClass is set to UmsUserRoleVOImpl
predicates.add(cb.equal(root.get(key), value)); // key is set to "userName" - this line is causing the exception
I get this error:
java.lang.IllegalArgumentException: Unable to locate Attribute with
the the given name [userName] on this ManagedType
[com.myapp.ums.business.impl.UmsUserRoleVOImpl]
But the attribute userName is included in my VO, as well as a public setter and it's mapped in my .hbm.xml file:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.myapp.ums.business.impl.UmsUserRoleVOImpl" table="ums_t_user_role"
proxy="com.myapp.ums.common.business.UmsUserRoleVO">
<composite-id>
<key-property name="userName" type="java.lang.String" column="fk_user_id"/>
<key-property name="roleName" type="java.lang.String" column="fk_role_id"/>
</composite-id>
</class>
</hibernate-mapping>
This is my VO:
public class UmsUserRoleVOImpl extends AbstractBasePropertiesImpl implements UmsUserRoleVO {
private static final long serialVersionUID = 2393634151578825216L;
private String roleName;
private String userName;
private List<PmPropertyVO> properties;
public UmsUserRoleVOImpl() {
}
#Get(AbstractBaseProperties.ROWGUID)
#Override
public Long getRowguid() {
return super.getRowguid();
}
#Set(AbstractBaseProperties.ROWGUID)
#Override
public void setRowguid(final Long rowguid) {
super.setRowguid(rowguid);
}
#Get(UmsUserRoleVO.ROLE_NAME)
public String getRoleName() {
return roleName;
}
#Set(UmsUserRoleVO.ROLE_NAME)
public void setRoleName(String roleName) {
this.roleName = roleName;
}
#GetCollection(value = UmsUserRoleVO.PROPERTIES, defaultObject = "com.myapp.pm.business.impl.PmPropertyVOImpl")
public List<PmPropertyVO> getProperties() {
return properties;
}
#SetCollection(value = UmsUserRoleVO.PROPERTIES, defaultObject = "com.myapp.pm.business.impl.PmPropertyVOImpl")
public void setProperties(List<PmPropertyVO> properties) {
this.properties = properties;
}
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof UmsUserRoleVOImpl)) {
return false;
}
UmsUserRoleVOImpl user = (UmsUserRoleVOImpl) o;
if (!(roleName.equals(user.getRoleName()))) {
return false;
}
return userName.equals(user.getUserName());
}
public int hashCode() {
int result = 17;
result = 29 * result + (roleName != null ? roleName.hashCode() : 0);
result = 29 * result + (userName != null ? userName.hashCode() : 0);
return result;
}
public String toString() {
return roleName + " " + userName;
}
#Get(UmsUserRoleVO.USER_NAME)
public String getUserName() {
return this.userName;
}
#Set(UmsUserRoleVO.USER_NAME)
public void setUserName(String userName) {
this.userName = userName;
}
There seems to be something wrong with the mapping, because Hibernate does not find any attribute of the UmsUserRoleVOImpl:
Any idea what could be causing this error?

Many-to-Many/Junction Table - Spring JPA Hibernate - could not set value by reflection

So,
I am trying to do a many to many implementation through Spring JPA.
I tried to do an embedded key implementation.
But I am getting this error
{
"message": "Internal server error",
"details": "Could not set field value [26] value by reflection : [class com.domain.configuredview.model.RelationshipViewPersonPK.personId] setter of com.domain.configuredview.model.RelationshipViewPersonPK.personId; nested exception is org.hibernate.PropertyAccessException: Could not set field value [26] value by reflection : [class com.domain.configuredview.model.RelationshipViewPersonPK.personId] setter of com.domain.configuredview.model.RelationshipViewPersonPK.personId"
}
I tried searching through all the answers but couldn't fix this.
My classes are
import com.domain.person.model.Person;
import java.io.Serializable;
import javax.persistence.*;
import lombok.Data;
import lombok.NoArgsConstructor;
#Data
#NoArgsConstructor
#Entity
#Table(name = "relationship_view_person")
public class RelationshipViewPerson implements Serializable {
#EmbeddedId
private RelationshipViewPersonPK entryId;
#ManyToOne(fetch = FetchType.LAZY)
#MapsId("viewId")
#JoinColumn(name = "view_id", nullable = false)
private ConfiguredView view;
#ManyToOne(fetch = FetchType.LAZY)
#MapsId("personId")
#JoinColumn(name = "person_id", nullable = false)
private Person person;
public RelationshipViewPerson(ConfiguredView view, Person person) {
this.view = view;
this.person = person;
this.entryId = new RelationshipViewPersonPK(view.getId(), person.getWsGlobalId());
}
public void setEntryId(Long viewId, String personId) {
this.entryId.setViewId(viewId);
this.entryId.setPersonId(personId);
}
public void setView(ConfiguredView view) {
this.view = view;
}
public void setPerson(Person person) {
this.person = person;
}
public Person getPerson() {
return this.person;
}
public ConfiguredView getView() {
return this.view;
}
}
The relationship key is
import java.io.Serializable;
import javax.persistence.*;
import lombok.NoArgsConstructor;
#Embeddable
#NoArgsConstructor
public class RelationshipViewPersonPK implements Serializable {
#Column(name = "view_id")
private Long viewId;
#Column(name = "person_id")
private String personId;
public RelationshipViewPersonPK(Long viewId, String personId) {
this.viewId = viewId;
this.personId = personId;
}
// setters & getters
public void setViewId(Long viewId) {
this.viewId = viewId;
}
public void setPersonId(String personId) {
this.personId = personId;
}
public String getPersonId() {
return this.personId;
}
public Long getViewId() {
return this.viewId;
}
// Override equals and hashCode
#Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (o == null || getClass() != o.getClass()) {
return false;
}
RelationshipViewPersonPK that = (RelationshipViewPersonPK) o;
return this.viewId.equals(that.viewId) && this.personId.equals(that.personId);
}
#Override
public int hashCode() {
return this.viewId.hashCode() + this.personId.hashCode();
}
}
The ConfiguredView model has PK as id and Person model has field as wsGlobalId . The key on the Person table is not a PK.
I have the setters, getters, constructors, and pretty much everyting in place. Not sure whats happening with Hibernate here, it cannot find the getter or something? Not sure whats happening with this.

You should have a setter like below:
public void setEntryId(RelationshipViewPersonPK entryId) {
this.entryId.setViewId(entryId.getViewId());
this.entryId.setPersonId(entryId.getPersonId());
}
instead of (or in addition to) this:
public void setEntryId(Long viewId, String personId) {
this.entryId.setViewId(viewId);
this.entryId.setPersonId(personId);
}

...extends JpaRepository
But, It doesn't solve the problem.
I don't have any mistakes. I only get null, but the requested row is in the table, that 's for sure.
does anyone have any ideas about this?
Why ?

Solution
The field we were working with had a data type CHAR(32 byte). We changed this type to VARCHAR(32 byte) into a table database of Oracle.
Now, Spring can build named query fine.
The project on older versions of Spring worked like this ...(CHAR(32 byte))
I don't understand why so.

Configuring JPA to handle HIBERNATE composite-id and key-property

I am trying to find the correct way to convert the below (Hibernate) XML to JPA annotations:
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<class name="TesTEntry" table="RAW_SCORE">
<composite-id mapped="false" unsaved-value="undefined">
<key-property column="SSN" name="ssn" type="string"/>
<key-property column="SUB_TEST_CD" name="subTestCd" type="string"/>
</composite-id>
<property column="TEST_QY" generated="never" lazy="false"
name="testQy" type="java.lang.Short"/>
<property column="SYS_REC" generated="never" lazy="false"
name="sysRec" type="java.util.Date"/>
<property column="SYS_ID" generated="never" lazy="false"
name="sysId" type="java.lang.String"/>
</class>
Since I have two <key-property> I am not sure if I use #Id, or #EmbeddedId

Since I have two I am not sure if I use #Id, or #EmbeddedId
You mean probably IdClass. And it doesn't matter which one you use.
Let us say, you want to use #IdClass:
Define a class for your ID.
Implement equals and hashCode methods
Implement public default constructor
Implement the Serializable interface
Here is an example implementation (equals & hashCode are generated from IDE):
public class TestEntityPK implements Serializable {
private static final long serialVersionUID = -3424067518791080014L;
private String ssn;
private String subTestCd;
public TestEntityPK() { // }
public TestEntityPK(String ssn, String subTestCd) {
this.ssn = ssn;
this.subTestCd;
}
public String getSsn() {
return ssn;
}
public String getSubTestCd() {
return subTestCd;
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((ssn == null) ? 0 : ssn.hashCode());
result = prime * result
+ ((subTestCd == null) ? 0 : subTestCd.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
TestEntityPK other = (TestEntityPK) obj;
if (ssn == null) {
if (other.ssn != null)
return false;
} else if (!ssn.equals(other.ssn))
return false;
if (subTestCd == null) {
if (other.subTestCd != null)
return false;
} else if (!subTestCd.equals(other.subTestCd))
return false;
return true;
}
}
And use it in the entity as follows:
#Entity
#Table(name="RAW_SCORE")
#IdClass(TestEntityPK.class)
public class TestEntity {
#Id private String ssn;
#Id
#Column(name="SUB_TEST_CD")
private String subTestCd;
#Column(name="TEST_QY")
private short testQy;
#Column(name="SYS_REC")
#Temporal(TemporalType.DATE)
private Date sysRec;
#Column(name="SYS_ID")
private String sysId;
// getters and setters
}

Spring Data JPA performnace issue with batch save

I have the following Entity
#Entity
#Table(name = "APP_ITEM")
public class AppItem implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
private AppItemPK AppItemPK;
public AppItemPK getAppItemPK() {
return appItemPK;
}
public void setAppItemPK(
AppItemPK appItemPK) {
this.appItemPK = appItemPK;
}
}
#Embeddable
public class AppItemPK implements Serializable {
private static final long serialVersionUID = 1L;
#Column(name = "app_id")
private Long appId;
#Column(name = "item_id")
private Long itemId;
public Long getAppId() {
return appId;
}
public void setAppId(Long appId) {
this.appId = appId;
}
public Long getItemId() {
return itemId;
}
public void setItemId(Long itemId) {
this.itemId = itemId;
}
public boolean equals(Object obj) {
if (obj instanceof AppItemPK) {
AppItemPK appItemPK = (AppItemPK) obj;
if (appItemPK.getItemId().equals(this.itemId)
&& appItemPK.getAppId().equals(
this.appId)) {
return true;
}
}
return false;
}
public int hashCode() {
return this.itemId.hashCode() + this.applicationId.hashCode();
}
}
Using below code to insert record into app_item table
#Transactional(readOnly = false)
public boolean saveItemSelection(PageHeaderViewData pageHeaderViewData, Map<Long, Boolean> selectedItems,String savedItems){
long millisSaveStart = Calendar.getInstance().getTimeInMillis();
log.debug("Inside saveItemSelection appId:"+pageHeaderData.getAppId());
boolean saveStatus = false;
List<AppItem> appItemInsList = new ArrayList<SavedApplicationItem>();
if (pageHeaderData.getAppId() != null) {
for (Entry<Long, Boolean> idEntry : selectedItems.entrySet() ) {
if (idEntry!= null){
if (idEntry.getValue() && !savedItems.contains(idEntry.getKey().toString())){
//log.debug("Inside saveItemSelection SAVED itemId:"+idEntry.getKey()+" , Value:"+idEntry.getValue());
AppItem appItem = new AppItem();
AppItemPK appItemPK = new AppItemPK();
appItemPK.setAppId(pageHeaderData.getAppId());
appItemPK.setItemId(idEntry.getKey());
appItem.setAppItemPK(appItemPK);
appItem.setUpdateInd(ToggleEnum.Y);
appItemInsList.add(appItem);
//appItemRepository.saveAndFlush(appItem);
}
}
}
}
if (appItemInsList.size() != 0){
long millisJPASaveStart = Calendar.getInstance().getTimeInMillis();
appItemRepository.save(appItemInsList);
long millisJPASaveEnd = Calendar.getInstance().getTimeInMillis();
log.debug("JPA save time:"+(millisJPASaveEnd-millisJPASaveStart));
}
saveStatus = true;
long millisSaveEnd = Calendar.getInstance().getTimeInMillis();
log.debug("Total save time:"+(millisSaveEnd-millisSaveStart));
}
return saveStatus;
}//end of saveItemSelection
For inserting 5000 records it is taking 13826 milliseconds.
Can someone please let me know, how to improve the performance in above JPA code. We are using hibernate for jpa implementation.

To improve the performance your inserts, you should implement batch insert using custom code. The method below will make sure that batches are flushed to the database. Tweak the batch size based on your performance tests. Generally 50 is a good number to start.
#Transactional
public void bulkPersist(List<Entity> entities) {
int i = 0;
for (Entity entity : entities) {
em.persist(entity);
i++;
if (i % batchSize == 0) {
flush();
clear();
}
}
}
Above change will create multiple insert statements. You can further optimize the insert query by setting up the hibernate configuration.
<prop key="hibernate.order_inserts">true</prop>
<prop key="hibernate.order_updates">true</prop>
Tip: Enable Debug log to see 1 insert query is being generated per batch.
