在Liferay 6.1中上傳多個文件

Question

有沒有人嘗試過在Liferay 6.1中上傳多個文件。我試圖以與6.0版相同的方式來執行它，並且它的失敗很嚴重。我看到頁面左上角的開始鏈接，而不是portlet。當我點擊並選擇一些文件時，控件不會轉到我的portlet。我檢查了我的portlet.xml並驗證了portlet類是否正確。下面是在JSP

<liferay-portlet:actionURL doAsUserId="<%= user.getUserId() %>" windowState="pop_up" name="uploadFile" var="uploadFileURL" > 
    <portlet:param name="jspPage" value="/html/fileuploadportlet/view.jsp" /> 
</liferay-portlet:actionURL> 


<div class="lfr-dynamic-uploader"> 
     <div class="lfr-upload-container" id="<portlet:namespace />fileUpload"></div> 
    </div> 
<div id="<portlet:namespace/>fallback"></div> 
<aui:script use="liferay-upload"> 
    new Liferay.Upload({ 
     allowedFileTypes: '<%= StringUtil.merge(PrefsPropsUtil.getStringArray(PropsKeys.DL_FILE_EXTENSIONS, StringPool.COMMA)) %>', 
     container: '#<portlet:namespace />fileUpload', 
     maxFileSize: <%=Long.parseLong(PrefsPropsUtil.getString(PropsKeys.DL_FILE_MAX_SIZE)) %>/1024, 
     namespace:'<%=renderResponse.getNamespace()%>', 
     uploadFile: '<%=uploadFileURL.toString()%>', 
     buttonHeight: 100, 
     buttonText: 'BEGIN', 
     buttonWidth: 100, 
     onFileComplete: function(){alert('fileComplete');}, 
     onUploadError: function(){alert('error');} 
    }); 
</aui:script> 

片斷，這裏是我的Portlet的processAction方法

@Override 
    public void processAction(ActionRequest actionRequest, 
      ActionResponse actionResponse) throws IOException, PortletException { 
     System.out.println("Something"); 
     UploadPortletRequest uploadRequest=PortalUtil.getUploadPortletRequest(actionRequest); 
     File file =uploadRequest.getFile("file"); 
     System.out.println(file.getName()); 
     for(int i=0;i<50000;i++){ 
      System.out.println("Something"); 
     } 

    }

您可以檢查您的<aui:script>是正確的，下面就是在HTML/portlet中所示/document_library/upload_multiple_file_entries.jsp，我認爲你缺少屬性tempFileURL：

<aui:script use="liferay-upload"> 
     new Liferay.Upload(
      { 
       allowedFileTypes: '<%= allowedFileExtensions %>', 
       container: '#<portlet:namespace />fileUpload', 
       deleteFile: '<liferay-portlet:actionURL doAsUserId="<%= user.getUserId() %>"><portlet:param name="struts_action" value="/document_library/edit_file_entry" /><portlet:param name="<%= Constants.CMD %>" value="<%= Constants.DELETE_TEMP %>" /><portlet:param name="folderId" value="<%= String.valueOf(folderId) %>" /></liferay-portlet:actionURL>&ticketKey=<%= ticket.getKey() %><liferay-ui:input-permissions-params modelName="<%= DLFileEntryConstants.getClassName() %>" />', 
       fileDescription: '<%= StringUtil.merge(PrefsPropsUtil.getStringArray(PropsKeys.DL_FILE_EXTENSIONS, StringPool.COMMA)) %>', 
       maxFileSize: '<%= PrefsPropsUtil.getLong(PropsKeys.DL_FILE_MAX_SIZE) %> B', 
       metadataContainer: '#<portlet:namespace />commonFileMetadataContainer', 
       metadataExplanationContainer: '#<portlet:namespace />metadataExplanationContainer', 
       namespace: '<portlet:namespace />', 
       tempFileURL: { 
        method: Liferay.Service.DL.DLApp.getTempFileEntryNames, 
        params: { 
         groupId: <%= scopeGroupId %>, 
         folderId: <%= folderId %>, 
         tempFolderName: 'com.liferay.portlet.documentlibrary.action.EditFileEntryAction' 
        } 
       }, 
       uploadFile: '<liferay-portlet:actionURL doAsUserId="<%= user.getUserId() %>"><portlet:param name="struts_action" value="/document_library/edit_file_entry" /><portlet:param name="<%= Constants.CMD %>" value="<%= Constants.ADD_TEMP %>" /><portlet:param name="folderId" value="<%= String.valueOf(folderId) %>" /></liferay-portlet:actionURL>&ticketKey=<%= ticket.getKey() %><liferay-ui:input-permissions-params modelName="<%= DLFileEntryConstants.getClassName() %>" />' 
      } 
     ); 
    </aui:script> 

希望這會有所幫助。
