1.异常处理
Exception in thread "main" org.apache.poi.openxml4j.exceptions.OLE2NotOfficeXmlFileException: The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF)
原因是：
HSSFWorkbook:是操作Excel2003以前（包括2003）的版本，扩展名是.xls
XSSFWorkbook:是操作Excel2007的版本，扩展名是.xlsx
2.NoClassDefFoundError: org/openxmlformats/schemas/drawingml/x2006/main/ThemeDocument
解决方法：添加poi-ooxml-schemas-3.12-20150511.jar
3. javax.mail.NoSuchProviderException: smtp 报错
下了最新的mailapi 1.4.7 版本, 把原来的那两个jar(activation-1.1.1.jar 和 mailapi-1.4.3 jar)从classpath中去掉， 把1.4.7 中lib全部加到classpath， 然后就发送成功了。
