fileUploadListener从未被调用(primefaces 5.0)

我试图使用PrimeFaces上传文件，但上传完成后没有调用fileUploadListener方法。我添加了jar common -io和commons-fileupload。

我使用

glassifish 3.1
primaespaces 5.0
eclipseLink
jsf 2。

我搜索了很多，但没有工作。这是我的代码。

管理Bean:

package image;
import java.io.IOException;
import java.io.InputStream;
import javax.ejb.EJB;
import javax.enterprise.context.SessionScoped;
import javax.faces.bean.ManagedBean;
import org.apache.commons.io.IOUtils;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.UploadedFile;

@ManagedBean(name="uploadBean")
@SessionScoped
public class UploadBean {
private UploadedFile file;
private Fichier fichier;
@EJB
private FichierDao fichierDao;
public UploadBean()
{
    fichier = new Fichier();
}
public void handleFileUpload(FileUploadEvent event) {
   file= event.getFile();
  // System.out.print("gfghfhgf"+file.getSize());
}
// Store file in the database
public void storeImage() {
    System.out.println("11111mamlamlmalmalmlkljkjkhkjhjhjghj");
    try {
        InputStream is =file.getInputstream() ;
        fichier.setKey(IOUtils.toByteArray(is));
        System.out.println("22222222mamlamlmalmalmlkljkjkhkjhjhjghj");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        System.out.println("33333333333mamlamlmalmalmlkljkjkhkjhjhjghj");
    }
    System.out.println("44444444444mamlamlmalmalmlkljkjkhkjhjhjghj");
    fichierDao.create(fichier);
    System.out.println("55555555555mamlamlmalmalmlkljkjkhkjhjhjghj");
}
public UploadedFile getFile() {
    return file;
}
public void setFile(UploadedFile file) {
    this.file = file;
}
public Fichier getFichier() {
    return fichier;

在任何提交文件上传或文件下载表单的命令组件上使用ajax="false"。

由于上传/下载是HTTP GET请求，不使用Ajax提交，这确实是POST请求。

<p:commandButton value="Submit" ajax="false"  action="#{uploadBean.storeImage}" />

下面是一个如何使用primefaces 5.0上传文件的示例;你不需要commons-fileupload-1.3.1.jar和commons-io-2.4.jar;而且你也不需要修改web.xml，并且在h:form中声明growl而不是在p:fileUpload中声明growl。更多信息请参见如何在primefaces中上传文件
