标签: java jopendocument

我有.ods文件,我想阅读并通过java程序显示它 我用过这个程序:

import java.io.File;
import java.io.IOException;

import org.jopendocument.dom.spreadsheet.MutableCell;
import org.jopendocument.dom.spreadsheet.Sheet;
import org.jopendocument.dom.spreadsheet.SpreadSheet;

public class ODSReader {
  public void readODS(File file)
  {
    Sheet sheet;
    try {
         //Getting the 0th sheet for manipulation| pass sheet name as string
         sheet = SpreadSheet.createFromFile(file).getSheet(0);

         //Get row count and column count
         int nColCount = sheet.getColumnCount();
         int nRowCount = sheet.getRowCount();

         System.out.println("Rows :"+nRowCount);
         System.out.println("Cols :"+nColCount);
         //Iterating through each row of the selected sheet
         MutableCell cell = null;
         for(int nRowIndex = 0; nRowIndex < nRowCount; nRowIndex++)
         {
           //Iterating through each column
           int nColIndex = 0;
           for( ;nColIndex < nColCount; nColIndex++)
           {
             cell = sheet.getCellAt(nColIndex, nRowIndex);
             System.out.print(cell.getValue()+ " ");
            }
            System.out.println();
          }

        } catch (IOException e) {
          e.printStackTrace();
        }
  }
  public static void main(String[] args) {
        //Creating File object of .ods file
        File file = new File("D:\\TestData\\test.ods");
        ODSReader objODSReader = new ODSReader();
        objODSReader.readODS(file);
  }
}

和.ods文件是这样的: enter image description here

,输出显示如下:

> Date 
  Volume 
  Open 
  Low 
  High 
  Close 
  Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7
    at org.jopendocument.dom.spreadsheet.Row.getCellAt(Unknown Source)
    at org.jopendocument.dom.spreadsheet.Row.getValidCellAt(UnknownSource)
    at org.jopendocument.dom.spreadsheet.Row.getMutableCellAt(Unknown

    at com.spreadSheets.java.ODSReader.readODS(ODSReader.java:38)
    at com.spreadSheets.java.Main.main(Main.java:20)

**问题是我如何显示字符,数字和符号 使用这个jopendocument包并避免或解决这些异常? **

2 个答案:

答案 0 :(得分:0)

sheet.getRowCount()

这样可以在工作表中为您提供最大行数,例如19534667,因此您不应该将其用于此。在我的项目中,我手动添加行数和列数。

答案 1 :(得分:0)

我无法使用您的代码重现您的错误。我认为您应该更新到jOpenDocument的1.3版。我只制作了5行的电子表格来测试您的代码。尽管如此,它还是很棒的。

不过,在代码中只有一件事,您不需要将nColIndex带到“ for”循环声明之外。

您的代码非常适合仅包含1张纸的ods文件,但是如果您有多张纸,则可能会遇到问题。我只是将您的代码进行了一些修改,以使其将来可以轻松进行编辑,以使该程序能够处理具有多个设计相似的工作表的电子表格。

import java.io.File;
import java.io.IOException;

import org.jopendocument.dom.spreadsheet.MutableCell;
import org.jopendocument.dom.spreadsheet.Sheet;
import org.jopendocument.dom.spreadsheet.SpreadSheet;

public class ODSReader {
  public void readODS(File file)
  {
    SpreadSheet spreadsheet;
    try {
         //Getting the 0th sheet for manipulation| pass sheet name as string

         spreadsheet = SpreadSheet.createFromFile(file);

         //Get row count and column count
         int nColCount = spreadsheet.getSheet(0).getColumnCount();
         int nRowCount = spreadsheet.getSheet(0).getRowCount();

         System.out.println("Rows :"+nRowCount);
         System.out.println("Cols :"+nColCount);
         //Iterating through each row of the selected sheet
         MutableCell cell = null;
         for(int nRowIndex = 0; nRowIndex < nRowCount; nRowIndex++)
         {
           //Iterating through each column
           for(int nColIndex = 0; nColIndex < nColCount; nColIndex++)
           {
             cell = spreadsheet.getSheet(0).getCellAt(nColIndex, nRowIndex);
             System.out.print(cell.getValue()+ " ");
            }
            System.out.println();
          }

        } catch (IOException e) {
          e.printStackTrace();
        }
  }
  public static void main(String[] args) {
        //Creating File object of .ods file
        File file = new File("test.ods");
        ODSReader objODSReader = new ODSReader();
        objODSReader.readODS(file);
  }
}
