解析xlsx文件---Java读取Excel2007

关于Java读取Excel2007的文章在Google、百度上搜索一下，没有太好的例子，实现的也不算太好。查看了一下Poi，最新的 POI 3.5 beta 4 支持读写 Excel2007和PPT2007(XLSX and PPTX)，自己来实现Java读取Excel2007了。

年的poi.jar；下面案例只适用于与解析格式较小的文件，对于较大的文件会出现内存溢出情况。

1，下载 POI 3.5 beta 4 解压，把其中的jar包导入项目文件。以我的读取为例，导入了以下jar包。

没有配置 log4j，测试时报告警报信息，应该为加载顺序导致的初始化问题造成(暂时没有找原因)。

2，建立读取 Excel2007 方法

Java代码

// 构造 XSSFWorkbook 对象，strPath 传入文件路径

XSSFWorkbook xwb = new XSSFWorkbook(path);  //已过时，被废弃，使用会出错

XSSFWorkbook xwb = new XSSFWorkbook(new FileInputStream(file));

// 读取第一章表格内容

XSSFSheet sheet = xwb.getSheetAt(0);

// 定义 row、cell

XSSFRow row;

String cell;

// 循环输出表格中的内容

for (int i = sheet.getFirstRowNum(); i < sheet.getPhysicalNumberOfRows(); i++) {

row = sheet.getRow(i);

for (int j = row.getFirstCellNum(); j < row.getPhysicalNumberOfCells(); j++) {

// 通过 row.getCell(j).toString() 获取单元格内容，

cell = row.getCell(j).toString();

System.out.print(cell + "\t");

}

System.out.println("");

}

// 构造 XSSFWorkbook 对象，strPath 传入文件路径

XSSFWorkbook xwb = new XSSFWorkbook(strPath);

// 读取第一章表格内容

XSSFSheet sheet = xwb.getSheetAt(0);

// 定义 row、cell

XSSFRow row;

String cell;

// 循环输出表格中的内容

for (int i = sheet.getFirstRowNum(); i < sheet.getPhysicalNumberOfRows(); i++) {

row = sheet.getRow(i);

for (int j = row.getFirstCellNum(); j < row.getPhysicalNumberOfCells(); j++) {

// 通过 row.getCell(j).toString() 获取单元格内容，

cell = row.getCell(j).toString();

System.out.print(cell + "\t");

}

System.out.println("");

}

此过程直接传入文件所在路径，其他一些过程已经被自动实现。

3，测试，文件为8列3563行数据，以文本方式读取内容，

Java代码

public static void main(String[] args) {

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss:SS");

TimeZone t = sdf.getTimeZone();

t.setRawOffset(0);

sdf.setTimeZone(t);

Long startTime = System.currentTimeMillis();

String fileName = "F:\\我的文档\\学生缴费代码.xlsx";

// 检测代码

try {

PoiReadExcel er = new PoiReadExcel();

// 读取excel2007

er.testPoiExcel2007(fileName);

} catch (Exception ex) {

Logger.getLogger(FastexcelReadExcel.class.getName()).log(Level.SEVERE, null, ex);

}

Long endTime = System.currentTimeMillis();

System.out.println("用时：" + sdf.format(new Date(endTime - startTime)));

}

public static void main(String[] args) {

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss:SS");

TimeZone t = sdf.getTimeZone();

t.setRawOffset(0);

sdf.setTimeZone(t);

Long startTime = System.currentTimeMillis();

String fileName = "F:\\我的文档\\学生缴费代码.xlsx";

// 检测代码

try {

PoiReadExcel er = new PoiReadExcel();

// 读取excel2007

er.testPoiExcel2007(fileName);

} catch (Exception ex) {

Logger.getLogger(FastexcelReadExcel.class.getName()).log(Level.SEVERE, null, ex);

}

Long endTime = System.currentTimeMillis();

System.out.println("用时：" + sdf.format(new Date(endTime - startTime)));

}

读取所用时间为：4.172秒。

二、java解析大数据分析

一. Apache POI 简介（ http://poi.apache.org/）

使用Java程序读写Microsoft Office，提供了下面这几种类型：

HSSF－提供读写Microsoft Excel XLS格式档案的功能。

XSSF－提供读写Microsoft Excel OOXML XLSX格式档案的功能。

HWPF－提供读写Microsoft Word DOC格式档案的功能。

HSLF－供读写Microsoft PowerPoint格式档案的功能。

HDGF－提供读Microsoft Visio格式档案的功能。

HPBF－提供读Microsoft Publisher格式档案的功能。

三、java解析excel大数据；临时表的形式

此篇是紧接上篇《大数据量的excel文件读取——2003及之前版本》。

excel2007文件格式与之前版本不同，之前版本采用的是微软自己的存储格式。07版内容的存储采用XML格式，所以，理所当然的，对大数据量的xlsx文件的读取采用的也是XML的处理方式SAX。

同之前的版本一样，大数据量文件的读取采用的是事件模型eventusermodel。usermodel模式需要将文件一次性全部读到内存中，07版的既然采用的存储模式是xml，解析用的DOM方式也是如此，这种模式操作简单，容易上手，但是对于大量数据占用的内存也是相当可观，在Eclipse中经常出现内存溢出。

下面就是采用eventusermodel对07excel文件读取。

同上篇，我将当前行的单元格数据存储到List中，抽象出 optRows 方法，该方法会在每行末尾时调用，方法参数为当前行索引curRow(int型)及存有行内单元格数据的List。继承类只需实现该行级方法即可。

补充：今天发现读取2007的脚本存在存在一处问题，在遇到空单元格时会跳过该单元格，由于工作紧张没有时间去解决该问题，这里给出一个暂时的处理办法。打开文件，在开始菜单中选择"查找和选择"，"定位条件"，选择"空值"，确定，这时会找出所有的空单元格，直接按空格，然后Ctrl+enter，就会将所有空单元格填入一个空格，保存即可。

2010.6.10补充：空单元格的问题已经解决，在2007的文档中空单元格是不存储的，单元格的r属性是单元格位置信息，格式为[A-Z]+[0-9]+。字母部分是列索引，数字部分是行索引。

抽象类：XxlsAbstract ，作用：遍历excel文件，提供行级操作方法 optRows
