Apache Poi 读写 word 文档

十二12

使用 Apache Poi 读写 word 文档

写操作:

package com.poi.word;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Date;
import java.util.List;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
/**
* 写入 word
* @author LGF 2015-01-03
*
*/
public class WriterWord {
public static void main(String[] args) throws IOException {
//创建文档对象
XWPFDocument doc = new XWPFDocument();
//创建 XWPFWordExtractor 传入 文档
XWPFWordExtractor we = new XWPFWordExtractor(doc);
//创建一个段落
XWPFParagraph paragraph = doc.createParagraph();
//一个XWPFRun代表具有相同属性的一个区域。  
XWPFRun run = paragraph.createRun();
//执行 10 遍写入 word 文档
for (int i = 0; i < 10; i++) {
run = doc.createParagraph().createRun();
run.setColor("ff0000");
run.setFontFamily("宋体");
run.setFontSize(15);
run.setText("第 "+i+" hello world ...  ");
}
//创建一个表格
XWPFTable table = doc.createTable(10, 3);
//    table.addNewCol(); //给表格增加一列
//    table.createRow(); //给表格新增一行
List<XWPFTableRow> rows = table.getRows();
for (XWPFTableRow r : rows) {
List<XWPFTableCell> cs = r.getTableCells();
for (int i = 0; i < cs.size(); i++) {
XWPFTableCell c = cs.get(i);
c.setText(i+" *_* " + new Date());
}
}
//写入
doc.write(new FileOutputStream("src/test.doc"));
//释放资源
we.close();
System.out.println("success");
}
}


读操作:
