primeface handleFileUpload不会触发 [英] primefaces handleFileUpload doesn't trigger

问题描述

我试图用primefaces fileUpload实现一个页面，但是我的handleUpload函数没有被触发。
My xhtml：

 < h：form enctype =multipart / form-data> 
< p：panel id =uploadFormPanelheader =文件上传> 
< h：panelGrid columns =2style =margin-bottom：10pxcellpadding =5> 
< h：outputText value =＃{criteriaTranslation.questionaireFile}：/> 
  fileUploadListener =＃{critereCSVImporter.handleFileUpload}
 mode =advanced
 allowTypes =/（\。| \ /）（CSV）$ //> 
< / h：panelGrid> 
< p：growl id =uploadMessagesshowDetail =true/> 
< / p：面板> 
< / h：表格> 
  

我的支持bean：

  @ManagedBean 
 @ViewScoped 
 public class CritereCSVImporter {
 
 @Inject 
 private CriteriaBL criteriaBL; 
 private String OCRMODE; 
 
 public void handleFileUpload（FileUploadEvent event）{
 System.out.println（handle）; 
 InputStream inputStream = event.getFile（）。getInputstream（）; 
 
  

我的web.xml：

 < filter> 
< filter-name> PrimeFaces FileUpload Filter< / filter-name> 
< filter-class> 
 org.primefaces.webapp.filter.FileUploadFilter 
< / filter-class> 
< / filter> 
< filter-mapping> 
< filter-name> PrimeFaces FileUpload Filter< / filter-name> 
< servlet-name> Faces Servlet< / servlet-name> 
< / filter-mapping> 
  

我错过了什么吗？

解决方案将commons-fileupload和commons-io jar放入你的lib文件夹中。 org / fileuploadrel =nofollow> Apache Commons FileUpload

Apache Commons IO

I'm trying to implement a page with primefaces fileUpload but my handleUpload function isn't triggered. My xhtml:

<h:form enctype="multipart/form-data">
  <p:panel id="uploadFormPanel" header="File upload">
     <h:panelGrid columns="2" style="margin-bottom:10px" cellpadding="5">  
         <h:outputText value="#{criteriaTranslation.questionaireFile}:" />
         <p:fileUpload update="uploadMessages"   
                       fileUploadListener="#{critereCSVImporter.handleFileUpload}"
                       mode="advanced"
                       allowTypes="/(\.|\/)(csv)$/"/>  
    </h:panelGrid>
    <p:growl id="uploadMessages" showDetail="true"/>
  </p:panel>
</h:form> 

My backing bean:

@ManagedBean
@ViewScoped
public class CritereCSVImporter {

@Inject
private CriteriaBL criteriaBL;
private String OCRMODE;

public void handleFileUpload(FileUploadEvent event) {
    System.out.println("handle");
    InputStream inputStream = event.getFile().getInputstream();
}

My web.xml:

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>
        org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

Am I missing something?

解决方案

Place commons-fileupload and commons-io jars in your lib folder

Apache Commons FileUpload
