Question

现在我正在使用Primefacs 3.3.1和JSF 2.0作为我的申请。现在我面临一个问题，即表面FileUploadEvent监听器即使表单提交也不起作用。我的日志文件中没有erorr和exception。但是，它不起作用。我缺少什么，lib或配置？顺便说一句，我使用JBoss 7.1.1应用程序服务器。

库

primefaces-3.3.1.jar
commons-io-1.4.jar
commons-fileupload-1.2.1.jar
poi-3.7.jar

mypages.xhtml

<h:form enctype="multipart/form-data">            
    <p:fileUpload fileUploadListener="#{FileUploadController.handleFileUpload}"  
            mode="advanced"  
            update="messages"   
            multiple="true"  
            sizeLimit="100000"   
            allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>  
    <p:commandButton value="Submit" ajax="false" actionListener="#{FileUploadController.upload}"/>  
    <!-- or -->
    <p:commandButton value="Submit" ajax="false" action="#{FileUploadController.upload}"/>  
</h:form>

FileUploadController.java

@Scope(ScopeType.CONVERSATION)
@Name("FileUploadController")
public class FileUploadController {
    private List<UploadedFile> uploadedFileList = new ArrayList<UploadedFile>();

    public void handleFileUpload(FileUploadEvent event) {
        System.out.println("handleFileUpload()....");
        UploadedFile file = event.getFile();
        uploadedFileList.add(file);
        FacesMessage msg = new FacesMessage("Succesful", file.getFileName() + " is uploaded.");  
        FacesContext.getCurrentInstance().addMessage(null, msg);  
    }  

    public void upload() {
        System.out.println("Number of Uploaded Files : " + uploadedFileList.size());
    }
}

Answer 1

你应该禁用缝多部分过滤器。你应该写

web：multipart-filter disabled =“true”/＆gt;在components.xml中。对我来说很好。
