POI3.8读取word文档的表格数据！

package cn.ccb.boup.util.poi;import java.io.FileInputStream;import java.io.IOException;import java.util.ArrayList;import java.util.Iterator;import java.util.List;import org.apache.poi.hwpf.HWPFDocument;import org.apache.poi.hwpf.usermodel.Paragraph;import org.apache.poi.hwpf.usermodel.Range;import org.apache.poi.hwpf.usermodel.Table;import org.apache.poi.hwpf.usermodel.TableCell;import org.apache.poi.hwpf.usermodel.TableIterator;import org.apache.poi.hwpf.usermodel.TableRow;import org.apache.poi.poifs.filesystem.POIFSFileSystem;/** *  * @author guojigang *  */public class OperateWord {/** * 读取word文档的表格数据 *  * @param filePath * @return List */public static List readWordCell(String filePath) {FileInputStream in = null;POIFSFileSystem pfs = null;List<String> list = new ArrayList<String>();try {in = new FileInputStream(filePath);// 载入文档pfs = new POIFSFileSystem(in);HWPFDocument hwpf = new HWPFDocument(pfs);Range range = hwpf.getRange();// 得到文档的读取范围TableIterator it = new TableIterator(range);// 迭代文档中的表格if (it.hasNext()) {TableRow tr = null;TableCell td = null;Paragraph para = null;String lineString;String cellString;Table tb = (Table) it.next();// 迭代行，从第2行开始for (int i = 2; i < tb.numRows(); i++) {tr = tb.getRow(i);lineString = "";for (int j = 0; j < tr.numCells(); j++) {td = tr.getCell(j);// 取得单元格// 取得单元格的内容for (int k = 0; k < td.numParagraphs(); k++) {para = td.getParagraph(k);cellString = para.text();if (cellString != null&& cellString.compareTo("") != 0) {// 如果不trim，取出的内容后会有一个乱码字符cellString = cellString.trim() + "|";}lineString += cellString;}}// 去除字符串末尾的一个管道符if (lineString != null && lineString.compareTo("") != 0) {lineString = lineString.substring(0, lineString.length() - 1);}list.add(lineString);}}} catch (Exception e) {e.printStackTrace();} finally {if (null != in) {try {in.close();} catch (IOException e) {e.printStackTrace();}}}return list;}public static void main(String[] args) {List list = OperateWord.readWordCell("C:\\身份核查结果.doc");for (Iterator iter = list.iterator(); iter.hasNext();) {String str = (String) iter.next();System.err.println(str);}}}

 所需类库：

poi-3.8-beta5-20111217.jar
poi-scratchpad-3.8-beta5-20111217.jar

可以从http://poi.apache.org/下载。

单独测试没问题，但放到项目里，会报下面的错误，应该是由于类冲突引起的。

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.poi.POIDocument.<init>(Lorg/apache/poi/poifs/filesystem/DirectoryNode;)V
 at org.apache.poi.hwpf.HWPFDocumentCore.<init>(HWPFDocumentCore.java:146)
 at org.apache.poi.hwpf.HWPFDocument.<init>(HWPFDocument.java:218)
 at org.apache.poi.hwpf.HWPFDocument.<init>(HWPFDocument.java:186)
 at cn.ccb.boup.util.poi.OperateWord.readWordCell(OperateWord.java:37)
 at cn.ccb.boup.util.poi.OperateWord.main(OperateWord.java:87)

解决办法是：打开项目的properties->java build path->order and export，发现poi的2个jar包放到了最后，把poi的包移到最上面。问题解决！
