我已被編程在Whiich使用2個模型類JavaFX應用程序：EJB，JavaFX的PU java.lang.IllegalArgumentException異常：對象：[email protected]不是已知的實體類型
package model;
import java.io.Serializable;
import java.util.ArrayList;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
@Entity
public class Person implements Serializable{
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
@OneToMany(cascade={CascadeType.PERSIST,CascadeType.MERGE},
fetch=FetchType.EAGER, mappedBy="Person")
private ArrayList<Produkt> products= new ArrayList<Produkt>();
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
private String email;
private String firstName;
private String lastName;
private String tel;
private String kleurCode;
private String facebook;
public Person() {
super();
}
public Person(String firstName, String lastName, String email,String tel, String facebook, String kleurCode) {
setFirstName(firstName);
setLastName(lastName);
setEmail(email);
setFacebook(facebook);
setTel(tel);
setKleurCode(kleurCode);
}
public ArrayList<Produkt> getProducts() {
return products;
}
public void setProducts(ArrayList<Produkt> products) {
this.products = products;
}
public void setFacebook(String tel)
{
this.facebook=tel;
}
public String getFacebook() {
return facebook;
}
public void setKleurCode(String tel)
{
this.kleurCode=tel;
}
public String getKleurCode() {
return kleurCode;
}
public String getTel()
{
return tel;
}
public void setTel(String tel)
{
this.tel=tel;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String fName) {
firstName=fName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String fName) {
lastName=fName;
}
public String getPrimary() {
return getEmail();
}
public String getSecondary() {
return getEmail();
}
public String getEmail() {
return email;
}
public void setEmail(String fName) {
email=fName;
}
}
package model;
import java.io.Serializable;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
@Entity
public class Produkt implements Serializable {
String naam;
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
@ManyToOne(cascade={CascadeType.PERSIST,CascadeType.MERGE},
fetch=FetchType.EAGER)
private Person person;
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
public Produkt() {
super();
}
public Produkt(Person p, String naam){
p=p;
naam=naam;
};
public String getNaam() {
return naam;
}
public void setNaam(String naam) {
this.naam = naam;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
那麼我此門面類：
package facade;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import model.Person;
import model.Produkt;
public class Facade {
@PersistenceContext(unitName = "EJBModuleDAPU")
private EntityManager em;
public Facade()
{
em=getEntityManager();
}
public void createPerson(Person p) {
if(em!=null){
em.persist(p);
}
else
{
System.out.println("EM was null");
}
}
public void createProduct(Produkt p) {
em.persist(p);
}
public void editProduct(Produkt p) {
em.merge(p);
}
public void editPerson(Person p) {
em.merge(p);
}
public void removePerson(Person p) {
em.remove(em.merge(p));
}
public void removeProduct(Produkt p) {
em.remove(em.merge(p));
}
public Person findPerson(Object id) {
return em.find(Person.class, id);
}
public Produkt findProduct(Object id) {
return em.find(Produkt.class, id);
}
public List<Person> findAllPerson() {
Query query = em.createQuery("SELECT m from Person as m");
return query.getResultList();
/*System.out.println(em.toString());
javax.persistence.criteria.CriteriaQuery cq = em.getCriteriaBuilder().createQuery();
cq.select(cq.from(Person.class));
return em.createQuery(cq).getResultList();*/
}
public List<Person> findAllProdcut() {
javax.persistence.criteria.CriteriaQuery cq = em.getCriteriaBuilder().createQuery();
cq.select(cq.from(Produkt.class));
return em.createQuery(cq).getResultList();
}
protected EntityManager getEntityManager() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("EJBModuleDAPU");
EntityManager ecm = emf.createEntityManager();
return ecm;
}
}
這裏是我的執着單位：
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="EJBModuleDAPU" transaction-type="JTA">

<shared-cache-mode>NONE</shared-cache-mode>
<validation-mode>NONE</validation-mode>
<properties>
<property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
</properties>
</persistence-unit>
</persistence>
應用程序運行，但是當我做了LO okup（），並嘗試添加聯繫人或得到所有的列表：
