我正在尝试读取xlsx格式的excel文件。但我得到的结果太大和无效的句柄异常。我将文件实例放在FileInputStream对象中，并尝试在XSSFWorkbook中设置该对象。但我得到了这个例外。
我在没有安装Microsoft Office并且有开放式办公室的环境中工作。我没有在开放式办公室中编辑我的xlsx文件。但是我在开放式办公室打开文件，然后尝试运行poi代码.Is这有什么问题吗？
我正在提供我的代码片段以及下面的例外我正在使用的罐子
commons-codec-1.10
commons-collections4-4.1
commons-io-2.5
commons-logging-1.2
curvesapi-1.04
ooxml-schemas-1.0
poi-3.17
poi-excelant-3.17
poi-ooxml-3.17
xmlbeans-2.3.0
这是我获得例外的代码，
private void openWorkbook(String fileName) throws IOException {
FileInputStream excelFile = new FileInputStream(new File(fileName));
try {
this.setWorkbook(new XSSFWorkbook(excelFile)); // here the exception is coccuring
} catch (Exception e) {
e.printStackTrace();
}finally{
excelFile.close();
}
}
我相信setWorkBook方法无法处理工作簿的大小。
我得到的例外是
