La imagen no se actualiza
La propiedad de la imagen no se está actualizando. Estoy usando this.user.setImage (a) para establecer el valor pero no funciona. Mi bean administrado está dentro del ámbito de solicitud.
1) Aquí está mi bean. El problema está en la función 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) Aquí está mi página xhml.
