我用过的jars:dom4j poi-3.8.jar
poi-ooxml-3.8.jar

xbean.jar
代码:

错误::
org.apache.poi.hssf.dev.BiffViewer$CommandParseException: Biff viewer needs a filename at org.apache.poi.hssf.dev.BiffViewer$CommandArgs.parse(BiffViewer.java:333) at org.apache.poi.hssf.dev.BiffViewer.main(BiffViewer.java:386)
答案 0 :(得分:0)
BiffViewer是HSSF的一部分,它只适用于较旧的.xls文件(基于OLE2)。您正在使用XSSF生成.xlsx文件,这是一种不同的低级格式。
如果你真的想使用BiffViewer(不知道为什么,它通常只用于调试,但仍然),那么你需要将你的XSSF代码更改为HSSF代码。否则,如果您的意思是使用XSSF生成.xlsx文件,则无法使用HSSF调试工具。如果您想知道.xlsx文件中的内容,请将其解压缩(.xlsx是xml文件的zip文件)并查看XML。
