我正在尝试按照 primefaces 用户指南中记录的内容进行工作，以及在那里创建的一些帖子。
Upload file in JSF primefaces .
环境是:javaee full + jpa + jsf 2.2 + primefaces 4 + glassfish v4
我又发帖了，因为我已经尝试了我在网上找到的所有示例和建议，但都没有成功。
我可以通过:event.getFile.getFileName 获取文件上传名称，但内容始终为空
------------更新----------------------------
我的 xhtml 页面:
<h:form enctype="multipart/form-data">
<p:outputLabel value="La photo :"/>
<p:fileUpload fileUploadListener="#{personController.upload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
我的托管 bean:
@Named(value = "personController")
@SessionScoped
public class PersonController implements Serializable {
/**
* Creates a new instance of PersonController
*/
@Inject
private PersonneFacade personneService;
private Personne current;
private Personne newPerson;
private List<Personne> personnes;
public PersonController() {
}
public List<Personne> getAll(){
return personneService.findAll();
}
public void upload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage("Success! ", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
// Do what you want with the file
System.out.println(event.getFile().getFileName());
System.out.println("le fichier " + event.getFile().getContents());
newPerson.setPhoto(event.getFile().getContents());
}

确定我有我的 pom.xml :

当我尝试上传时，我看到了 glassfish 输出日志:
INFO: mdmx.jpg
INFO: le fichier null
有什么想法吗？？
