我正在使用POI 3.9和SXSSF来创建电子表格。当行数较少时,创建超链接会起作用。但是,随着大小的增加,处理时间大大增加,链接也不起作用。它适用于700行但不是70,000行。尝试打开文件时,会发生此错误:
Excel在'out.xlsx'中找到了不可读的内容。你想恢复这个工作簿的内容吗?如果您信任此工作簿的来源,请单击“是”。
public static void main(String[] args) throws Throwable {
Workbook wb = new SXSSFWorkbook(100); // keep 100 rows in memory, exceeding rows will be flushed to disk
Sheet sh = wb.createSheet();
for(int rownum = 0; rownum < 70000; rownum++){
Row row = sh.createRow(rownum);
for(int cellnum = 0; cellnum < 10; cellnum++){
Cell cell = row.createCell(cellnum);
String address = new CellReference(cell).formatAsString();
cell.setCellValue(address);
if (address.contains("A"))
setHyperlink(cell, address);
}
}
FileOutputStream out = new FileOutputStream("C:/temp/sxssf.xlsx");
wb.write(out);
out.close();
}
protected static void setHyperlink(Cell cell, String address) {
Workbook workbook = cell.getSheet().getWorkbook();
Hyperlink hyperlink = workbook.getCreationHelper()
.createHyperlink(Hyperlink.LINK_URL);
String encoded = null;
try {
encoded = URLEncoder.encode(address, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
hyperlink.setAddress(encoded);
cell.setHyperlink(hyperlink);
}

看起来excel上的最大超链接数限制为66,530。 http://office.microsoft.com/en-in/excel-help/excel-specifications-and-limits-HP010073849.aspx
