jsf-2 - Rich faces 4.2.3 文件上传不调用backing bean方法

Question

我正在尝试使用richfaces 文件上传，而fileUploadListener 没有在我的backingbean 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");
    }
}

Answer 1

如您的代码所示，您绑定到文件上传组件的方法是“uploadFile”，但您在 fileUploadBean 中提供的侦听器名称为“listener”。应该是，fileUploadListener="#{fileUploadBean.listener}"
