POI生成word

关于POI生成word，有两种方式，一是新建文件写入内容，二十使用模版生成。

一、新建文件写入内容（以内容是个），代码如下：

package com.rn.wisdom.utils;import java.io.FileOutputStream;import java.io.IOException;import java.io.OutputStream;import java.math.BigInteger;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletResponse;import org.apache.commons.lang.ObjectUtils.Null;import org.apache.poi.sl.usermodel.VerticalAlignment;import org.apache.poi.ss.usermodel.Cell;import org.apache.poi.ss.usermodel.Row;import org.apache.poi.xwpf.usermodel.ParagraphAlignment;import org.apache.poi.xwpf.usermodel.VerticalAlign;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.XWPFVertAlign;import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTJc;import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl;import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblPr;import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblWidth;import org.openxmlformats.schemas.wordprocessingml.x2006.main.STJc;import org.openxmlformats.schemas.wordprocessingml.x2006.main.STTblWidth;/** * word 导出 * */public class WordExporter {private XWPFDocument document;private String title;//标题public WordExporter(String title) {document = new XWPFDocument();this.title = title;setTite();}//设置word标题public void setTite() {XWPFParagraph paragraph = document.createParagraph();paragraph.setAlignment(ParagraphAlignment.CENTER);XWPFRun run = paragraph.createRun();run.setText(title);run.setBold(true);run.setFontFamily("宋体");run.setFontSize(22);}    //设置表格public void setContent() {//写入内容XWPFParagraph paragraph = document.createParagraph();//段落XWPFTable table = document.createTable(）;//表格}//下载public void responseExport( String fileName) {try {FileOutputStream out = new FileOutputStream(fileName);document.write(out);out.close();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public static void main(String[] args) throws IOException {WordExporter wordExporter = new WordExporter("测试"); wordExporter.setContent();wordExporter.responseExport("D:\\测试.docx");} }

二、使用模版生成word，HWPFDocument只支持.doc格式的模版

package com.rn.wisdom.utils;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.util.HashMap;import java.util.Iterator;import java.util.List;import java.util.Map;import java.util.regex.Matcher;import java.util.regex.Pattern;import javax.servlet.http.HttpServletResponse;import org.apache.poi.hwpf.HWPFDocument;import org.apache.poi.hwpf.model.PropertyNode.EndComparator;import org.apache.poi.hwpf.usermodel.Range;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;/** * word 导出 使用模版导出 版本有限制模版只能是.doc * */public class WordExporter3 {private HWPFDocument document;private InputStream in;/** * 初始化文档 * */public WordExporter3(String filename) {try {in = new FileInputStream(filename);document = new HWPFDocument(in);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}/** * 替换数据 * @param params * */public void replaceData(Map<String, String> params) {Range range = document.getRange();for (Map.Entry<String, String> entry : params.entrySet()) {range.replaceText(entry.getKey(), entry.getValue());}}/** * 导出 * @param response * @param fileName 导出文档名 * */public void responseExport( String fileName) {try {FileOutputStream out = new FileOutputStream(fileName);document.write(out);out.close();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public static void main(String[] args) throws IOException {WordExporter3 wordExporter = new WordExporter3("D:\\测试.doc");Map<String, String> map = new HashMap<>();map.put("${title}", "你好");map.put("${column1}", "helloword");map.put("${column2}", "你好");map.put("${column3}", "你好");map.put("${column4}", "你好");map.put("${column5}", "你好");map.put("${column6}", "2行2列");map.put("${column7}", "2行3列");map.put("${column8}", "2行4列");map.put("${column9}", "3行2列");map.put("${column10}", "3行2列");wordExporter.replaceData(map);wordExporter.responseExport("D:\\测试2.docx");} }
