java uses POI tool to read word document and write to generate new word document and error sorting

First, read the word document and write to generate a new word document:

1. Use the toolkit: poi-version.jar poi-scratchpad-version-beta5.jar or poi-scratchpad-version.jar

2. Code:

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.model.FieldsDocumentPart;
import org.apache.poi.hwpf.usermodel.Field;
import org.apache.poi.hwpf.usermodel.Fields;
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;

public class WordTest
{

/**

public static void main(String[] args)
{
Map<String, String> map = new HashMap<String, String>();
map.put("${name}", "张三");
map.put("${age}", "20");
map.put("${province}", "山西");
map.put("${city}", "太原");
map.put("${district}", "迎泽区");
map.put("${school}", "test");
String srcPath = "C:\\Users\\Administrator\\Desktop\\test.doc";
readwriteWord(srcPath, map);
}

/**

public static void readwriteWord(String filePath, Map<String, String> map)
{
// read word template
// String fileDir = new
// File(base.getFile(),"http://www.cnblogs.com/http://www.cnblogs.com/../doc/").getCanonicalPath();
FileInputStream in = null;
try
{

}
catch (FileNotFoundException e1)
{
e1.printStackTrace();
}
HWPFDocument hdt = null;
try
{
hdt = new HWPFDocument(in);
}
catch (IOException e1)
{
e1.printStackTrace();
}
Fields fields = hdt.getFields();
Iterator<Field> it = fields.getFields(FieldsDocumentPart.MAIN)
.iterator();
while (it.hasNext())
{
System.out.println(it.next().getType());
}

//read word text content
Range range = hdt.getRange();
TableIterator tableIt = new TableIterator(range);
//Iterate the table in the document
int ii = 0;
while (tableIt.hasNext()) {
Table tb = (Table) tableIt. next();
ii++;
System.out.println("The "+ii+" table data.......");
//Iterate over rows, default from 0 starts
for (int i = 0; i < tb.numRows(); i++) {
TableRow tr = tb.getRow(i);
//read only the first 8 rows, header part
if(i >=8) break;
//iteration Column, starting from 0 by default
for (int j = 0; j < tr.numCells(); j++) {
TableCell td = tr.getCell(j);//Get the cell
//Get the content of the cell
for(int k =0;k<td.numParagraphs();k++){
Paragraph para =td.getParagraph(k);
String s = para.text();
System.out.println(s);
} //end for
} //end for
} //end for
} //end while
//System.out.println(range.text());

// 替换文本内容
for (Map.Entry<String, String> entry : map.entrySet())
{
range.replaceText(entry.getKey(), entry.getValue());
}
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
String fileName = "" + System.currentTimeMillis();
fileName += ".doc";
FileOutputStream out = null;
try
{
out = new FileOutputStream("F:/" + fileName, true);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
try
{
hdt.write(ostream);
}
catch (IOException e)
{
e.printStackTrace();
}
// 输出字节流
try
{
out.write(ostream.toByteArray());
}
catch (IOException e)
{
e.printStackTrace();
}
try
{
out.close();
}
catch (IOException e)
{
e.printStackTrace();
}
try
{
ostream.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}

2. Problem sorting:

Error content: org.apache.poi.poifs.filesystem.POIFSFileSystem.getRoot()

Lorg/apache/poi/poifs/filesystem/DirectoryNode error!

Solution: Upgrade the poi-version number.jar package
