尝试使用Apache POI打印xlsx内容

Question

我想阅读.xlsx文件并显示内容。为此，我添加了这些库：

• 的xmlbeans-2.6.0.jar
• POI-3.11-20141221.jar
• POI-例子-3.11-20141221.jar
• POI-excelant-3.11-20141221.jar
• POI-OOXML-3.11-20141221.jar
• POI-OOXML-架构 - 3.11-20141221.jar
• POI暂存器-3.11-20141221.jar

我收到此错误：

  

用法：BiffDrawingToXml [options] inputWorkbook选项：
  -exclude-workbook排除工作簿级别记录-sheet-indexes具有指定索引的输出表单-sheet-namek具有指定名称的输出表单

有人能告诉我发生了什么事吗？这是代码：
