使用POI解析Excel时，出现org.xml.sax.SAXParseException: duplicate attribute 'o:relid'的解决办法

1.使用org.apache.poi解析excle，.xlsx类型文件
InputStream is = new FileInputStream(strFileName);
XSSFWorkbook wb = new XSSFWorkbook(is);
出现异常如下：

org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException

解决办法有点复杂，请大家尝试；

 InputStream is = new FileInputStream(strFileName);

 OPCPackage pkg = OPCPackage.open(is);

 PackagePart p = null;

 for(PackagePart part:pkg.getParts()){

 　　if(part.getPartName().getName().equals("/xl/drawings/vmlDrawing1.vml")){

 　　　　p = part;

 　　}

 }

 if(p != null){

 　　pkg.removePart(p);

 }
12 XSSFWorkbook wb = new XSSFWorkbook(pkg);

1.使用OPCPackage解压读入的excel流，然后找到出错的那个part，例如/xl/drawings/vmlDrawing1.vml。
2.使用pkg.removePart(p)方法，remove掉就出错的part可以解决了。
3.不过目前只解决了自己遇到的问题，如果大家是其他的part有问题，需要测试一下remove掉后，XSSFWorkbook是否能够正确解析。
