我正在尝试阅读.xls，.xlsm和.xlsx工作表。
如果尝试读取.xls工作表，代码将正常工作，但如果尝试读取.xlsm和.xlsx工作表，则显示异常。我已经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
但是我也低于错误-

最佳答案
Excel生成错误的xml。可能会特别。
阅读此内容：https://bz.apache.org/bugzilla/show_bug.cgi?id=53819
它是由错误的xml引起的。
可以通过手动删除属性的重复定义来解决此问题。
堆栈跟踪表明该文件包含无效的xml。我检查了附件，确实如此：
/xl/drawings/vmlDrawing1.vml包含不允许重复的属性，
看看下面的fragmentnt：
<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，找到此文件并进行修复。
