如何使用Jexcel API编辑/修改Java中的现有Excel文件

我想用Java编辑现有的Excel文件，以便将更多数据添加到现有模板excel文件中。 所以我用Jexcel就是为了这个目的。

无处不在，我尝试了以下方法，

Workbook existingWorkbook = Workbook.getWorkbook(new File("H://"+file_name)); WritableWorkbook copy = Workbook.createWorkbook(new File("H://"+file_name+"_temp1.xls")); 

但它在第二行显示例外。

 jxl.common.AssertionFailed at jxl.common.Assert.verify(Assert.java:37) at jxl.read.biff.SheetReader.handleObjectRecord(SheetReader.java:1811) at jxl.read.biff.SheetReader.read(SheetReader.java:1059) at jxl.read.biff.SheetImpl.readSheet(SheetImpl.java:716) at jxl.read.biff.WorkbookParser.getSheet(WorkbookParser.java:257) at jxl.write.biff.WritableWorkbookImpl.copyWorkbook(WritableWorkbookImpl.java:969) at jxl.write.biff.WritableWorkbookImpl.(WritableWorkbookImpl.java:343) at jxl.Workbook.createWorkbook(Workbook.java:339) at jxl.Workbook.createWorkbook(Workbook.java:320) at run_book.process_input.(process_input.java:83) <--create workbook stt. ......... 

那么如何编辑已经存在的jexcel文件呢？ 我确实得到了另一个警告

警告：不支持工作表“sheet2”上的文本对象 – 省略

提前致谢 ：）

找出问题所在。

在写回（编辑）同一文件之前，我们必须关闭输入文件。

所以使用Jexcel编辑现有的Excel文件

 File inp = new File("H://"+file_name); File out = new File("H://"+file_name); Workbook existingWorkbook = Workbook.getWorkbook(inp);// This opens up a read-only copy of the workbook WritableWorkbook copy = Workbook.createWorkbook(out,existingWorkbook); // This opens up a writable workbook so that we can edit the copy //..........Some writes to excel workbook........... // Now before writing & closing the copy, first close the existing one existingWorkbook.close(); // Important: Close it before writing the copy with copy.write(); inp.close(); copy.write(); copy.close();

我遇到了同样的问题并解决了我通过maven更新到最新版本的jxl.jar的问题。 执行此操作后，运行destinationWorkbook = Workbook.createWorkbook(outputFile, sourceWorkbook);时出现了很长的延迟destinationWorkbook = Workbook.createWorkbook(outputFile, sourceWorkbook); 但它成功完成没有错误。
