Question

我正在尝试使用richfaces文件上传，而fileUploadListener没有在我的backbean中调用监听器。

我的xthml中的代码

 <rich:fileUpload fileUploadListener="#{fileUploadBackingBean.uploadFile}"
                maxFilesQuantity="#{fileUploadBackingBean.uploadsAvailable}"
                id="uploadfls" 
                immediateUpload="#{fileUploadBackingBean.autoUpload}"
                acceptedTypes="pdf,vnd.ms-excel,msexcel,xls" allowFlash="#{fileUploadBackingBean.useFlash}">
</rich:fileUpload>

BackingBean代码

@ManagedBean(name = "fileUploadBean")
public class FileUploadBean {


public void listener(FileUploadEvent event) throws Exception {
    System.out.println("listener");
    }
}

如代码所示，绑定到文件上载组件的方法是“uploadFile”，但是您在fileUploadBean中提供的侦听器名称为“listener”。应该是的， fileUploadListener = “＃{fileUploadBean.listener}”

检查以下示例， http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=fileUpload
