В моем приложении (Primefaces + Hibernate + Oracle DB) Я пытаюсь сохранить сущность, которая имеет список массивов целых чисел (manageesIds) для двух таблиц (arraylist будет зайдите в таблицу «details»).Сохранение списка массивов из целых чисел в Hibernate вызывает исключение
Он выдает исключение ClassCastException при попытке сохранить объект с помощью веб-приложения. Однако он отлично работает, когда я вызываю метод updateJobDescription из основного метода, а не из веб-приложения.
Entity:
@SuppressWarnings("serial")
@Entity
@Table(name = "EMP_JOB_DESCRIPTION")
public class EmployeeInfo
{
public EmployeeInfo()
{
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
manageesIds.add(new Integer(1));
}
@Id
@Column(name = "emp_no")
private Integer empNo;
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public String getEmail()
{
return email;
}
public void setEmail(String email)
{
this.email = email;
}
public String getOfficialPosition()
{
return officialPosition;
}
public void setOfficialPosition(String officialPosition)
{
this.officialPosition = officialPosition;
}
@Column(name = "emp_national_id_no")
private String nationalIdNo;
@Column(name = "emp_jawal_phone")
private String mobile;
@Column(name = "emp_phone_ext")
private String extension;
@Column(name = "emp_onreal_job_type")
private Integer actualPositionId;
@Column(name = "emp_st_old_dest")
private Integer workDestination;
@Column(name = "emp_city")
private Integer cityId;
@Column(name = "emp_specialty_desc")
private String specialtyDesc;
@Column(name = "emp_duties_desc")
private String dutiesDesc;
@Column(name = "emp_mng_job_desc")
private Integer managerPositionId;
@Column(name = "emp_qualification")
private Integer qualificationId;
@Column(name = "emp_last_qualification")
private Integer lastQualificationId;
@Column(name = "emp_experience")
private String experience;
@Column(name = "emp_training")
private String training;
@Transient
private String name;
@Transient
private String email;
@Transient
private String officialPosition;
@ElementCollection
@CollectionTable(name = "emp_job_description_detail", joinColumns = @JoinColumn(name = "EMP_NO"))
@Column(name = "EMP_MNG_CHAIRED_JOB_DESC")
private List<Integer> manageesIds = new ArrayList<Integer>();
Сохранить метод:
public static synchronized void updateJobDescription(EmployeeInfo jobDesc)
{
Session session = getNewSession(true);
session.saveOrUpdate(jobDesc);
closeSession(session, true);
}

Update:
Здесь как я называю это из главного метода:
public static void main(String[] args)
{
EmployeeInfo empInfo = new EmployeeInfo();
empInfo.setEmail("[email protected]");
empInfo.setEmpNo(7);
empInfo.setMobile("5698535");
empInfo.setName("Sary");
empInfo.setOfficialPosition("Dev Manager");
empInfo.setNationalIdNo("123456789");
List<Integer> ids = new ArrayList<Integer>();
ids.add(1);
empInfo.setManageesIds(ids);
updateJobDescription(empInfo);
}
Что касается веб-приложения, кнопка команды вызывает метод управляемой компоненты.
кнопку Commnad в Xhtml файле:
<p:commandButton value="#{msg.fourth_save}" ajax="false" actionListener="#{updateBean.updateJobDescription}" />
Управляемый боб:
public void updateJobDescription()
{
// save all entered info
PersistenceManager.updateJobDescription(empInfo);
// return navigation to first page
wizard.setStep(FIRST_STEP);
}
Как вы называете его от основного метода и как из веб-приложения? – user1983983
@ user1983983 Вопрос обновлен, чтобы включить вызов метода. – SaryAssad
