Изображение не обновляется
Свойство изображения не обновляется. Я использую this.user.setImage (a) для установки значения, но оно не работает. Мой управляемый bean-компонент является областью запроса.
1) Вот мой бин. Проблема в функции handleFileUpload.
package com.bean;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseId;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.servlet.http.HttpSession;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.UploadedFile;
import com.entity.User;
public class UserUpdateBean {
User user;
private EntityManager em;
private UploadedFile uploadedFile;
public UserUpdateBean(){
EntityManagerFactory emf=Persistence.createEntityManagerFactory("FreeBird");
em=emf.createEntityManager();
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
User s=(User) session.getAttribute("userdet");
user = em.find(User.class,s.getEmail());
}
public void handleFileUpload(FileUploadEvent e) {
System.out.println("file handler called");
uploadedFile = e.getFile();
String fileName=uploadedFile.getFileName();
fileName=fileName.substring(fileName.lastIndexOf("\\")+1);
System.out.println(fileName);
byte[] a = uploadedFile.getContents();
PhaseId currentPhaseId = FacesContext.getCurrentInstance().getCurrentPhaseId();
System.out.println("current phase id"+currentPhaseId);
user.setImage(a);
}
public String update(){
em.getTransaction().begin();
em.persist(user);
em.getTransaction().commit();
System.out.println("updated successful");
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
session.setAttribute("userdet", user);
return "success";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
2) Вот моя страница в формате xhml.
