我使用JSF,我有这个问题,当表单有te attibute enctype =“multipart / form-data”时h:commandButton没有从托管bean一侧触发任何操作,当我删除该属性是工作精细。但这不是我做的,因为我使用fileupload。
这是我的表格:
<h:form enctype="multipart/form-data" class="form-horizontal" id="form-catastrofe">
<p:growl id="messages" showDetail="true" />
<div class="form-group">
<div class="col-sm-12">
<p:fileUpload fileUploadListener="#{catastrofeBean.handleFileUploadImagen}" mode="advanced" dragDropSupport="false"
multiple="false" allowTypes="/(\.|\/)(gif|jpe?g|png)$/"
label="Elegir Icono"
cancelLabel="Cancelar"
update="messages" />
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<p:inputText id="inputname" value="#{catastrofeBean.catastrofe.nombre}" required="true" label="Name" styleClass="form-control">
<f:validateLength minimum="2" />
</p:inputText>
<p:watermark for="inputname" value="Nombre de Evento" id="watermarkName" />
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<p:inputText id="inputdescripcion" value="#{catastrofeBean.catastrofe.descripcion}" required="true" label="Name" styleClass="form-control"/>
<p:watermark for="inputdescripcion" value="Descripcion" id="watermarkDesc" />
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<p:inputText id="inputdireccion" value="#{catastrofeBean.catastrofe.direccion}" required="true" label="Name" styleClass="form-control"/>
<p:watermark for="inputdireccion" value="Direccion" id="watermarkDireccion" />
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<p:fileUpload fileUploadListener="#{catastrofes.handleFileUpload}" mode="advanced" dragDropSupport="false"
multiple="true" allowTypes="/(\.|\/)(pdf)$/"
label="Elegir Plan"
cancelLabel="Cancelar"
update="messages" />
</div>
</div>
<h:commandButton value="Ingresar Catástrofe" action="#{catastrofeBean.update}" class="pull-right btn btn-success"></h:commandButton>
</h:form>
这是我的web.xml:

有什么想法吗?我试图将bean更改为@ViewScoped,更改为@RequestScoped而没有。
这是我的托管bean:
@Named
@Stateful
@ConversationScoped
public class CatastrofeBean implements Serializable
{
private static final long serialVersionUID = 1L;
/*
* Support creating and retrieving Catastrofe entities
*/
private Long id;
public Long getId()
{
return this.id;
}
public void setId(Long id)
{
this.id = id;
}
private Catastrofe catastrofe;
public Catastrofe getCatastrofe()
{
return this.catastrofe;
}
@Inject
private Conversation conversation;
@Inject
private CatastrofeDao catastofeDao;
public String create()
{
this.conversation.begin();
return "create?faces-redirect=true";
}
/*
* Support updating and deleting Catastrofe entities
*/
public String update()
{
this.conversation.end();
try
{
if (this.id == null)
{
this.catastofeDao.create(this.catastrofe);
return "search?faces-redirect=true";
}
else
{
this.catastofeDao.update(this.catastrofe);
return "view?faces-redirect=true&id=" + this.catastrofe.getId();
}
}
catch (Exception e)
{
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(e.getMessage()));
return null;
}
}
public void handleFileUploadImagen(FileUploadEvent event) {
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);
}
public void handleFileUpload(FileUploadEvent event) {
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);
}
}
感谢。

我终于明白了问题所在,我错过了在web.xml中定义Faces Servlet。
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>

您没有显示为JSF
注释导入的软件包。你可能导入错误的。见this
