java - 使用 POI 读取 .xlsm 和 .xlsx 时出现异常

Question

我正在尝试阅读 .xls、.xlsm 和 .xlsx 表。如果尝试读取 .xls 表，代码可以正常工作，但如果尝试读取 .xlsm 和 .xlsx 表则显示异常。我已经在我的类路径中配置了必要的 jars 文件-

poi-3.8-20120326.jar,
poi-examples-3.8-20120326.jar,
poi-excelant-3.8-20120326.jar,
poi-ooxml-3.8-20120326.jar,
poi-ooxml-schemas-3.8-20120326.jar,
poi-scratchpad-3.8-20120326.jar,
ooxml-schemas-1.0.jar,
xmlbeans-2.3.0.jar,
dom4j-1.6.1.jar,
geronimo-stax-api_1.0_spec-1.0.1.jar

但后来我也得到了错误-

Answer 1

Excel 生成错误的 xml。可能是特别的。

阅读：https ://bz.apache.org/bugzilla/show_bug.cgi?id=53819

它是由错误的 xml 引起的。

这可以通过手动删除属性的重复定义来解决。

堆栈跟踪告诉该文件包含无效的 xml。我检查了附件，确实如此： /xl/drawings/vmlDrawing1.vml 包含不允许的重复属性，请查看以下片段：

  <v:fill o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1"
   o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1"
   o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1"
   o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1"
   o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1" o:relid="rId1"

您可以将 xslx 作为 zip 存档打开，找到此文件并修复它。

您可能需要POI-XSSF来读取新格式的 XLS 文件（亲切地命名为 .XLSX）。
