Question

我试图阅读.xls，.xlsm和.xlsx表。如果尝试读取.xls工作表，代码可以正常工作，但如果尝试读取.xlsm和.xlsx工作表则显示异常。我在类路径中配置了必要的jar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

但是我也遇到了错误 -

Answer 1

Excel生成了错误的xml。可能是特别的。

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

由错误的xml引起。

这可以通过manully删除duplcate属性定义来解决。

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，看看以下fragemnt：

  <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打开为zip存档，找到此文件并进行修复。

Answer 2

您可能需要POI-XSSF才能阅读新格式的XLS文件（精心命名为.XLSX）。

使用POI读取.xlsm和.xlsx时出现异常
