如何導入用java

Question

我收到錯誤出類拔萃有超過10萬行的文件到MySQL數據庫：

Exception in thread "main" org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF) at org.apache.poi.poifs.storage.HeaderBlock.(HeaderBlock.java:128) at org.apache.poi.poifs.storage.HeaderBlock.(HeaderBlock.java:112) at org.apache.poi.poifs.filesystem.NPOIFSFileSystem.(NPOIFSFileSystem.java:300) at org.apache.poi.poifs.filesystem.POIFSFileSystem.(POIFSFileSystem.java:86) at importdata.Snomed10.main(Snomed10.java:28)

Answer 1

如果我們看一下這個片段在這裏：

FileInputStream input = new FileInputStream("D://icd10 to snomed.xlsx"); 
POIFSFileSystem fs = new POIFSFileSystem(input); 
//HSSFWorkbook wb = new HSSFWorkbook(fs); 
XSSFWorkbook wb = new XSSFWorkbook(input); 

我們看到了問題。那麼，兩個問題，但...

因爲explained in the JavaDocs, POIFSFileSystem是讀取OLE2文件，如.xls的低級代碼。它不能打開OOXML文件，如.xlsx，這正是異常告訴你的！

其次，如explained in the docs，如果您有文件，請勿使用流！

所以，你的代碼應該改爲類似：

File input = new File("D://icd10 to snomed.xlsx"); 
OPCPackage pkg = OPCPackage.open(input); 
XSSFWorkbook wb = new XSSFWorkbook(pkg);
