java 导出word_Java使用word模板导出word

xmltoken.factory

1.创建一个空的springboot工程,引入jar包

org.apache.poi

poi-ooxml

3.17

org.apache.poi

poi

3.17

2.工具类一

package com.example.demo.util;

import org.apache.poi.openxml4j.opc.OPCPackage;

import org.apache.poi.xwpf.usermodel.XWPFDocument;

import org.apache.poi.xwpf.usermodel.XWPFParagraph;

import java.io.IOException;

import java.io.InputStream;

public class CustomXWPFDocument extends XWPFDocument {

public CustomXWPFDocument(InputStream in) throws IOException {

super(in);

}

super(pkg);

}

public void createPicture(String blipId,int id, int width, int height, XWPFParagraph paragraph)

{

final int EMU = 9525;

width *= EMU;

height *= EMU;

//给段落插入图片

CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();

String picXml = "" +

XmlToken xmlToken = null;

try

}

}

inline.set(xmlToken);

inline.setDistT(0);

import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

import java.text.SimpleDateFormat;

import java.util.Date;

import java.util.HashMap;

import java.util.Map;

@RestController

public class ExportWordController {

@RequestMapping(value = "/export")

public void export(HttpServletRequest request,HttpServletResponse response) throws Exception {

Map params = new HashMap<>();

params.put("${Name}", "Fisher3652");

params.put("${Sex}", "男");

params.put("${Desc}", "18岁\tJAVA开发\r熟悉JVM基本原理");

params.put("${@Pic}", "C:\\Users\\111\\Pictures\\123.jpg");

//spring项目使用此方法获取文件路径

// String fileNameInResource = request.getSession().getServletContext().getRealPath("Demo.docx");

InputStream is;

CustomXWPFDocument doc;

//spring项目使用此方法获取创建文件

// is = new FileInputStream(new File(fileNameInResource));

//springboot项目使用次方法

is = FileUtil.class.getClassLoader().getResourceAsStream("static/Demo.docx");

doc = new CustomXWPFDocument(is);

WordUtil xwpfTUtil = new WordUtil();

xwpfTUtil.replaceInPara(doc, params);

xwpfTUtil.replaceInTable(doc, params);

OutputStream os = response.getOutputStream();

response.setContentType("application/vnd.ms-excel");

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");

String fileName = sdf.format(new Date());

response.setHeader("Content-type", "text/html;charset=UTF-8");

response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".doc");

doc.write(os);

xwpfTUtil.close(os);

xwpfTUtil.close(is);

os.flush();

os.close();

System.out.println("word成功生成");

}
