javapoiword读取

❶ java 利用poi 可以直接读取word中的表格保持样式生成新的word么

1.读取word
2003及word
2007需要的jar包
读取
2003
版本(.doc)的word文件相对来说比较简单，只需要
poi-3.5-beta6-20090622.jar
和
poi-scratchpad-3.5-beta6-20090622.jar
两个
jar
包即可，
而
2007
版本(.docx)就麻烦多，我说的这个麻烦不是我们写代码的时候麻烦，是要导入的
jar
包比较的多，有如下
7
个之多：
1.
openxml4j-bin-beta.jar
2.
poi-3.5-beta6-20090622.jar
3.
poi-ooxml-3.5-beta6-20090622.jar
4
.dom4j-1.6.1.jar
5.
geronimo-stax-api_1.0_spec-1.0.jar
6.
ooxml-schemas-1.0.jar
7.
xmlbeans-2.3.0.jar
其中
4-7
是
poi-ooxml-3.5-beta6-20090622.jar
所依赖的
jar
包（在
poi-bin-3.5-beta6-20090622.tar.gz
中的
ooxml-lib
目录下可以找到）。
2.换行符号
硬换行：文件中换行，如果是键盘中使用了"enter"的换行。
软换行：文件中一行的字符数容量有限，当字符数量超过一定值时，会自动切到下行显示。
对程序来说，硬换行才是可以识别的、确定的换行，软换行与字体大小、缩进有关。
3.读取的注意事项
值得注意的是：
POI
在读取不会读取
word
文件中的图片信息；
还有就是对于
2007
版的
word(.docx),
如果
word
文件中有表格，所有表格中的数据都会在读取出来的字符串的最后。
4.读取word文本内容代码

❷ java 中用poi读取word和用docx4j读取word

不知道你是具体读取Word里面的什么元素，下面以读取文字和图片为例吧，两个代码示例，你参考看看:

1. 读取文本
   

import com.spire.doc.Document;

import java.io.FileWriter;

import java.io.IOException;

public class ExtractText {

public static void main(String[] args) throws IOException {

//加载Word文档
Document document = new Document();
document.loadFromFile("C:\Users\Administrator\Desktop\sample.docx");

//获取文档中的文本保存为String
String text=document.getText();

//将String写入Txt文件
writeStringToTxt(text,"ExtractedText.txt");
}

public static void writeStringToTxt(String content, String txtFileName) throws IOException {

FileWriter fWriter= new FileWriter(txtFileName,true);
try {
fWriter.write(content);
}catch(IOException ex){
ex.printStackTrace();
}finally{
try{
fWriter.flush();
fWriter.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}

}

2. 读取图片

import com.spire.doc.Document;

import com.spire.doc.documents.DocumentObjectType;

import com.spire.doc.fields.DocPicture;

import com.spire.doc.interfaces.ICompositeObject;

import com.spire.doc.interfaces.IDocumentObject;

import javax.imageio.ImageIO;

import java.awt.image.BufferedImage;

import java.io.File;

import java.io.IOException;

import java.util.ArrayList;

import java.util.LinkedList;

import java.util.List;

import java.util.Queue;

public class ExtractImages {

public static void main(String[] args) throws IOException {

//加载Word文档

Document document = new Document();

document.loadFromFile("C:\Users\Administrator\Desktop\sample.docx");

//创建Queue对象

Queue nodes = new LinkedList();

nodes.add(document);

//创建List对象

List images = new ArrayList();

//遍历文档中的子对象

while (nodes.size() > 0) {

ICompositeObject node = nodes.poll();

for (int i = 0; i < node.getChildObjects().getCount(); i++) {

IDocumentObject child = node.getChildObjects().get(i);

if (child instanceof ICompositeObject) {

nodes.add((ICompositeObject) child);

//获取图片并添加到List

if (child.getDocumentObjectType() == DocumentObjectType.Picture) {

DocPicture picture = (DocPicture) child;

images.add(picture.getImage());

}

}

}

}

//将图片保存为PNG格式文件

for (int i = 0; i < images.size(); i++) {

File file = new File(String.format("output/图片-%d.png", i));

ImageIO.write(images.get(i), "PNG", file);

}

}

}

注意这里使用的jar包是spire.doc.jar，需要在java程序中先导入jar文件。

❸ JAVA使用POI读写word 乱码

写

public static void main(String args[])
throws Exception
{
XWPFDocument doc = new XWPFDocument();
XWPFParagraph p1 = doc.createParagraph();
p1.setAlignment(ParagraphAlignment.CENTER);
p1.setBorderBottom(Borders.DOUBLE);
p1.setBorderTop(Borders.DOUBLE);
p1.setBorderRight(Borders.DOUBLE);
p1.setBorderLeft(Borders.DOUBLE);
p1.setBorderBetween(Borders.SINGLE);
p1.setVerticalAlignment(TextAlignment.TOP);
XWPFRun r1 = p1.createRun();
r1.setBold(true);
r1.setText("The quick brown fox");
r1.setBold(true);
r1.setFontFamily("Courier");
r1.setUnderline(UnderlinePatterns.DOT_DOT_DASH);
r1.setTextPosition(100);
XWPFParagraph p2 = doc.createParagraph();
p2.setAlignment(ParagraphAlignment.RIGHT);
p2.setBorderBottom(Borders.DOUBLE);
p2.setBorderTop(Borders.DOUBLE);
p2.setBorderRight(Borders.DOUBLE);
p2.setBorderLeft(Borders.DOUBLE);
p2.setBorderBetween(Borders.SINGLE);
XWPFRun r2 = p2.createRun();
r2.setText("jumped over the lazy dog");
r2.setStrike(true);
r2.setFontSize(20);
XWPFRun r3 = p2.createRun();
r3.setText("and went away");
r3.setStrike(true);
r3.setFontSize(20);
r3.setSubscript(VerticalAlign.SUPERSCRIPT);
XWPFParagraph p3 = doc.createParagraph();
p3.setWordWrap(true);
p3.setPageBreak(true);
p3.setAlignment(ParagraphAlignment.BOTH);
p3.setSpacingLineRule(LineSpacingRule.EXACT);
p3.setIndentationFirstLine(600);
XWPFRun r4 = p3.createRun();
r4.setTextPosition(20);
r4.setText("To be, or not to be: that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And by opposing end them? To die: to sleep; ");
r4.addBreak(BreakType.PAGE);
r4.setText("No more; and by a sleep to say we end The heart-ache and the thousand natural shocks That flesh is heir to, 'tis a consummation Devoutly to be wish'd. To die, to sleep; To sleep: perchance to dream: ay, there's the rub; .......");
r4.setItalic(true);
XWPFRun r5 = p3.createRun();
r5.setTextPosition(-10);
r5.setText("For in that sleep of death what dreams may come");
r5.addCarriageReturn();
r5.setText("When we have shuffled off this mortal coil,Must give us pause: there's the respectThat makes calamity of so long life;");
r5.addBreak();
r5.setText("For who would bear the whips and scorns of time,The oppressor's wrong, the proud man's contumely,");
r5.addBreak(BreakClear.ALL);
r5.setText("The pangs of despised love, the law's delay,The insolence of office and the spurns.......");
FileOutputStream out = new FileOutputStream("simple.docx");
doc.write(out);
out.close();
}

❹ java用POI第三方API操作word的时候，读取最终状态

java读取word文档时，虽然网上介绍了很多插件poi、java2Word、jacob、itext等等，poi无法读取格式(新的API估计行好像还在处于研发阶段，不太稳定，做项目不太敢用)；java2Word、jacob容易报错找不到注册，比较诡异，我曾经在不同的机器上试过，操作方法完全一致，有的机器不报错，有的报错，去他们论坛找高人解决也说不出原因，项目部署用它有点玄；itxt好像写很方便但是我查了好久资料没有见到过关于读的好办法。经过一番选择还是折中点采用rtf最好，毕竟rtf是开源格式，不需要借助任何插件，只需基本IO操作外加编码转换即可。rtf格式文件表面看来和doc没啥区别，都可以用word打开，各种格式都可以设定。
