JAVA用POI解析EXCEL

所需jar包：

dom4j-1.6.1.jar

poi-3.6-2009114.jar

poi-ooxml-3.6-20091214.jar

poi-ooxml-schemas-3.6-20091214.jar

poi-scratchpad-3.6-20091214.jar

xmlbeans-2.3.0.jar

geronimo-stax-api-1.0_spec-1.0.jar

 

jar见附件

 

 代码如下：

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Iterator;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ExcelUtil {

	/**
	 * 读取Excel文件的内容
	 * 
	 * @param file
	 *            待读取的文件
	 * @return 封装进集合的公文信息实体
	 */
	public static void parseExcel(String fileName) {
		boolean isE2007 = false; // 判断是否是excel2007格式
		if (fileName.endsWith("xlsx"))
			isE2007 = true;
		try {
			InputStream input = new FileInputStream(fileName); // 建立输入流
			Workbook wb = null;
			// 根据文件格式(2003或者2007)来初始化
			if (isE2007)
				wb = new XSSFWorkbook(input);
			else
				wb = new HSSFWorkbook(input);
			Sheet sheet = wb.getSheetAt(0); // 获得第一个表单
			Iterator<Row> rows = sheet.rowIterator(); // 获得第一个表单的迭代器
			while (rows.hasNext()) {
				Row row = rows.next(); // 获得行数据
				System.out.println("Row #" + row.getRowNum()); // 获得行号从0开始
				Iterator<Cell> cells = row.cellIterator(); // 获得第一行的迭代器
				while (cells.hasNext()) {
					Cell cell = cells.next();
					System.out.println("Cell #" + cell.getColumnIndex());
					switch (cell.getCellType()) { // 根据cell中的类型来输出数据
					case HSSFCell.CELL_TYPE_NUMERIC:
						System.out.println(cell.getNumericCellValue());
						break;
					case HSSFCell.CELL_TYPE_STRING:
						System.out.println(cell.getStringCellValue());
						break;
					case HSSFCell.CELL_TYPE_BOOLEAN:
						System.out.println(cell.getBooleanCellValue());
						break;
					case HSSFCell.CELL_TYPE_FORMULA:
						System.out.println(cell.getCellFormula());
						break;
					default:
						System.out.println("unsuported sell type");
						break;
					}
				}
			}
		} catch (IOException ex) {
			ex.printStackTrace();
		}
	}
}  

 ps：期间有异常

org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException抛出，在网上查说是jar包冲突，加了

dom4j-1.6.1.jar

geronimo-stax-api_1.0_spec-1.0.jar

xmlbeans-2.3.0.jar这3个jar包后，终于正常，问题详细见http://blog.csdn.net/shaobinteng/article/details/7008016
