POI操作WORD

POI操作WORD

 

POI操作word有很多局限性并不完善，所以用它的一个扩展包

1、环境支持

    1.1 添加poi支持：包下载地址http://www.apache.org/dyn/closer.cgi/poi/release/

     1.2 POI对Excel文件的读取操作比较方便，POI还提供对Word的DOC格式文件的读取。但在它的发行版本中没有发布对Word支持的模块，需要另外下载一个POI的扩展的Jar包。下载地址为http://www.ibiblio.org/maven2/org/textmining/tm-extractors/0.4/ 下载extractors-0.4_zip这个文件

下面给几个例子看看

写的不好还希望大家多提意见

测试

package com.ray.poi.util;

import junit.framework.TestCase;

public class POIUtilTest extends TestCase {

 public void testReadDoc() {
  try{
            String text = POIWordUtil.readDoc("E:/work_space/poi/com/ray/poi/util/demo.doc");
            System.out.println(text);
         }catch(Exception e){
             e.printStackTrace();
         }

 }

 public void testWriteDoc() {
     String wr;
  try {
   wr = POIWordUtil.readDoc("E:/work_space/poi/com/ray/poi/util/demo.doc");

    boolean b = POIWordUtil.writeDoc("c://demo.doc",wr);
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
