CRUD example problem
Hi ..I have an little problem .In my Example I want to edit my user detail .but every time when push Update button it creates new data like new user..but I want to update existing user. :( I think problem on updatePerson() action ..
here is my codes
This is person class
import java.util.HashSet;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import org.jboss.seam.annotations.Name;
@Entity
@Table(name = "PERSON")
public class Person {
private Long id;
public String firstname;
public String lastname;
public String phonenumber;
public String addres;
private Set<PersonLesson> personLessons = new HashSet<PersonLesson>(0);
@Id
@GeneratedValue
@Column(name = "PERSON_ID")
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Column(name = "FIRST_NAME")
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
@Column(name = "LAST_NAME")
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
@Column(name = "PHONE_NUMBER")
public String getPhonenumber() {
return phonenumber;
}
public void setPhonenumber(String phonenumber) {
this.phonenumber = phonenumber;
}
@Column(name = "ADDRES")
public String getAddres() {
return addres;
}
public void setAddres(String addres) {
this.addres = addres;
}
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "person")
public Set<PersonLesson> getPersonLessons() {
return personLessons;
}
public void setPersonLessons(Set<PersonLesson> personLessons) {
this.personLessons = personLessons;
}
}
This is PersonUtil class
import java.util.ArrayList;
import java.util.List;
import javax.persistence.EntityManager;
import org.jboss.seam.Component;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
@Name("personutil")
@Scope(ScopeType.CONVERSATION)
public class PersonUtil {
private Person activePerson ;
private List<Person> persons = new ArrayList<Person>();
private Lesson newLesson ;
public PersonUtil() {
activePerson = new Person();
initPersonList();
}
public void activePerson(Person kisi){
this.activePerson = kisi ;
}
public Lesson getNewLesson() {
return newLesson;
}
public void setNewLesson(Lesson newLesson) {
this.newLesson = newLesson;
}
public Person getActivePerson() {
return activePerson;
}
public void setActivePerson(Person activePerson) {
this.activePerson = activePerson;
}
public void initPersonList() {
EntityManager em = (EntityManager) Component.getInstance("entityManager");
List<Person> result = em.createQuery("from Person")
.getResultList();
setPersons(result);
}
public List<Person> getPersons() {
return persons;
}
public void setPersons(List<Person> persons) {
this.persons = persons;
}
public void initPerson(Person person) {
this.activePerson = person;
}
public void savePerson() {
EntityManager em = (EntityManager) Component.getInstance("entityManager");
em.persist(activePerson);
em.flush();
}
public void removePerson(Person person) {
EntityManager em = (EntityManager) Component.getInstance("entityManager");
em.remove(person);
em.flush();
}
public void updatePerson(Person person) {
EntityManager em = (EntityManager) Component.getInstance("entityManager");
em.persist(person);
em.flush();
}
}
