我想阅读一个由Power Builder应用程序生成的excel文件(Office的第4版)。 这是代码:
Users
|
+--UserID
| |
| +--UserInfo
| | |
| | +--Name
| | +--Phone
| | +--etc..
| |
| +--Records
| | |
| | +--RecordName
| | | |
| | | +--recordValue
| | | +--recordType
| | +--RecordName
| | | |
| | | +--recordValue
| | | +--recordType
当我尝试使用POI库v3.17读取excel文件时,它会抛出此异常:
File xls = new File("D:/excel.xls");
InputStream fis = new FileInputStream(xls);
HSSFWorkbook book = new HSSFWorkbook(fis);
由于excel文件是一个非常旧的版本,我尝试使用POI v3.0-FINAL(我找不到旧版本)读取它并抛出此异常:
org.apache.poi.poifs.filesystem.NotOLE2FileException: Invalid header signature; read 0x0010000200040009, expected 0xE11AB1A1E011CFD0 - Your file appears not to be a valid OLE2 document
at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:144)
我尝试用odbc
读取excel文件java.io.IOException: Invalid header signature; read 4503608217567241, expected -2226271756974174256
at org.apache.poi.poifs.storage.HeaderBlockReader.<init>(HeaderBlockReader.java:100)
但它引发了异常:
String myDB = "jdbc: odbc: Driver = {Microsoft Excel Driver (*.xls)}; DBQ = d: /excel.xls;" + "DriverID = 22; READONLY = false";
Connection with = DriverManager.getConnection (myDB, "", "");
我还尝试使用jxl库
读取excel文件java.sql.SQLException: [Microsoft] [ODBC Driver Manager] The name of
the data source is not found and no default drivers were specified
但抛出这个例外:
Workbook workbook = Workbook.getWorkbook (new File ("d:/excel.xls"));
任何人都可以帮我阅读任何Java库的excel文件版本4(1994)吗? 提前致谢
我正在使用jdk 1.7
答案 0 :(得分:0)
Apache POI HSSF格式适用于.xls文件。您尝试读取的文件是.xml。尝试使用XSSF类。
XSSFWorkbook book = new XSSFWorkbook(fis);
