poi解析excel文件报错

getFileMagic() only operates on streams which support mark(int)

使用 bis 解决

        BufferedInputStream bis = new BufferedInputStream(new FileInputStream(new File(path)));
        XSSFWorkbook xssfWorkbook = new XSSFWorkbook(bis);

找不到类，一般是版本问题，可以把版本调整一致，3.15
java.lang.reflect.InvocationTargetException
org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException

Java.lang.NoClassDefFoundError :org/openxmlformats/schemas/spreadsheetml/x2006/main/ctextensionlist

pom配置，版本保持一致，3.15
