使用Primefaces 4.0上传文件无法正常工作

时间：2014-04-03 12:11:48

标签： spring jsf file-upload primefaces

我有一个申请。这是一个简单的应用程序，其中一个功能是文件上传（仅限txt）。所以我使用了PrimeFaces的文件上传组件，但它不起作用。我尝试了很多东西，但我无法解决这个问题。我在WildFly 8.0上运行应用程序，我使用Spring和JPA。

依赖项（pom.xml）

声明了更多依赖项，但我认为只有这些依赖项被PrimeFaces使用。如果您需要查看我的整个pom.xml，请与我们联系。

同样，只有与primefaces相关的部分。

XHTML文件。

这是我尝试上传的文件。

<h:form id="uplFileForm" enctype="multipart/form-data">
    <p:fileUpload id="uplFile"
                  fileUploadListener="#{myManagedBean.save}"
                  mode="advanced"
                  auto="true"
                  label="Select the file"
                  uploadLabel="Upload"
                  cancelLabel="Cancel"
                  invalidSizeMessage="File is too big"
                  invalidFileMessage="Format not supported"

                  sizeLimit="614572800"
                  allowTypes="/(\.|\/)(txt|TXT)$/" />
</h:form>

我的托管Bean

嗯，这里我有接收文件并保存的方法，但是当我调试应用程序时，方法save(FileUploadEvent)永远不会被调用。我认为问题不在这里，因为，就像我说的那样，方法save(FileUploadEvent)没有被调用。

@ManagedBean
@ViewScoped
public class MyManagedBean extends AbstractMB implements Serializable {
    public void save(FileUploadEvent event) {
        try {
            String fileName = event.getFile().getFileName();

            MyFileUpload myFile = new MyFileUpload();
            byte[] content = event.getFile().getContents();

            myFile.setFilename(event.getFile().getFileName());
            myFile.setContent(conteudo);
            myFile.setChecksum(getHelperService().getCheckSum(content));
            save(myFile);
        }
        catch (ServiceException ex) {
            logger.error("Error, ex);
         }
    }
}

例外

<强>解决！

WildFly在执行请求时具有10mb的默认限制。我不得不增加这个限制。所以我打开文件<WILDFLY_HOME>/standalone/conf/standalone.xml并找到以下行：

<http-listener name="default" socket-binding="http"/>

我已经添加了属性max-post-size：

<http-listener name="default" socket-binding="http" max-post-size="51200000"/>

它有效！

尝试我在我的项目中使用它并且它已经工作了。

将Bean保留在@SessionScoped。

如果Bean用于上传图像，那么：

public class ImageController extends BaseWebController implements Serializable{ 

private static final long serialVersionUID = -3975946403680318499L; 
private StreamedContent image;

/**
 * @return the image
 */
public StreamedContent getImage() {

    PeopleDTO people = getCurrentUser();
    byte[] img = people.getUserPhoto();
    if(img != null){
        image = new DefaultStreamedContent(new ByteArrayInputStream(img));
    }else{
        image = null;
    }
    return image;
}

/**
 * @param image the image to set
 */
public void setImage(StreamedContent image) {
    this.image = image;
}

@PostConstruct
public void init() throws FileNotFoundException, IOException{
    image = getImage();
}

/**
 * @author NeelanjanaG
 * @param event
 */
public void handleFileUpload(FileUploadEvent event) {
    UploadedFile uploadedFile = event.getFile();

    byte[] img = uploadedFile.getContents();
    PeopleDTO peopleDTO = getCurrentUser();
    peopleDTO.setUserPhoto(img);
    try {
             new PeopleDAOManager().saveOrUpdate(peopleDTO);
        } catch (Exception e) {
            e.printStackTrace();
        }        
   }
}

然后在* .xhtml文件中（在我的情况下）写如：

<h:form prependId="false" id="myProfileForm" enctype="multipart/form-data">
    <h:panelGrid>
        <h:panelGroup layout="block" styleClass="moreInformation">
           <p:fileUpload id="fileUpload" 
                         styleClass="imageStyle" 
                         mode="advanced" dragDropSupport="false" 
                         update="myProfileForm:growl myProfileForm:profileImage" 
                         multiple="false" widgetVar="upload" 
                         sizeLimit="1000000" 
                         fileUploadListener="#{imageController.handleFileUpload}" 
                         allowTypes="/(\.|\/)(gif|jpe?g|png|tiff|exif)$/"/>
        <h:panelGroup>
    </h:panelGrid>
 </h:form>

在web.xml文件中，请添加以下内容：

<mime-mapping>
    <extension>png</extension>
    <mime-type>image/png</mime-type>
</mime-mapping>
<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>

对我来说很好！ 试试这个让我知道！

我和jsf 2.2有同样的问题。以下上下文参数解决了我的问题：

<context-param>
    <param-name>primefaces.UPLOADER</param-name>
    <param-value>commons</param-value>
</context-param>

答案 3 :(得分：-2)

尝试在web.xml中添加类似的内容：

<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>
